Lateness (same with non-compliance of a group and non-participation of a member) is not an option here anymore, for obvious reasons. Also, you are expected to email me ASAP your Documentary Clip’s URL or uniform resource locator so I can have an inventory of your internet addresses.<br /><br />Reminder: Note that your Debate Group is supposed to conceptualize, direct, design and upload your report on your power plant. The intention is to put whatever media, apps, information, style, and facilities that you have into a 15-20 minute movie clip convincing the cyber audience that your source of energy is necessary, beneficial and practical to be utilized in the Philippines. The process of hauling the raw materials, of generating power, and of transmitting the produced electricity must also be included in the report. This YouTube material is good for 100 points and must be participated in by ALL members of the group. <br /><br />Criteria: Content and Style Used, 40%, Number of YouTube likes, 20%, Organization of Ideas, 20%, Originality and Overall Impact, 20%. Same grading policy applies as the eventual triangulation based on the Group Leader’s Narrative Report, teacher’s observation, and members’ anecdotal reports will be given premium in the evaluation process.<br /><br />Consequently, this implies that the said Power Plant Documentary Clip in Physics will be included in the Fourth Quarter Grading.<br /><br />Should there be any clarification, kindly PM the teacher in his Herman M. Lagon Facebook Account.<br /><br />Please inform others.<br /><br />Enjoy your Christmas and New Year, mga anak! <br /><br />Magis! As always, never waste time and space!<br /><br />Lovingly yours,<br /><br />Engr. Herman M. Lagon, Ph.D.<br />Physics Teacher<br />Subject Area Coordinator<br /><br /><br />PS: For those who have already started or are just polishing their Documentary Clip, I give you my three-thumbs up! Saludo ako sa inyo for doing the Atenean Way. Please do not sigh, for the extension will give you more time to better your masterpiece. Who knows, you may get a perfect score and some extra credits for your work of science (and art). Please give my Seasons Greetings to your family and friends.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3988717207032365808-3814885695165526473?l=p6withsirh.blogspot.com' alt='' /></div>Engr.

Laptop must be secured by the owner at all times. It must not be left unattended. The school will not be liable to any damage or loss of the device.<br />2. Charging of laptop in school is prohibited. This is a form of stealing or power pilferage thus punishable by suspension.<br />3. Use of laptop is only allowed during breaks (recess, lunchtime, before or after classes), and never during class hours.<br />4. POD slip that allows the use of the laptop in school must be attached to the back portion of the laptop monitor when in use. This will right away give the school (teachers and staff) the idea that the laptop has POD permission.<br />5. Laptop use is only exclusive for physics chores. It will not be utilized anymore for other concerns (especially games, illicit sites, or other forms of entertainment).<br />6. Connection to the school’s wireless fidelity line is prohibited, unless allowed by the appropriate school authorities.<br /><br />We all are aware that any violation of the abovementioned rules and conditions may mean, to the least, confiscation of the laptop. <br /><br />Thank you so much.<br /><br />Respectfully yours,<br /><br /><br />___________________________ _________________________ _____________________ <br />Signature over Printed Name Signature over Printed Name Signature over Printed Name<br /> <br /><br />Year and Section: ________________________ <br />Debate Topic: _____________________________________<br /><br />Title of Investigative Project: _________________________________________________________________<br /><br /><br />Noted:<br /><br /><br />Engr.

Each group in the actual debate is given 20 minutes to briefly discuss its assigned topic and the succeeding 35 minutes for the debate (to defend it in a class that has its own energy source biases). Please see rubric for the criteria for judging<br /><br />► REPORTING. Each group will report on their assigned Source of Energy for 20 minutes. Here, the functions and processes of their energy source in terms of extraction, hauling, generation, transmission, and distribution should be equitably discussed by all the members coupled with visual illustrations (including videos and two-dimensional visuals), explanations, and skits (if necessary) before the class.<br />Reporters (all are required to do the reporting in English) should also show to class the reasons why their energy source must be used and how does it fare better compared to other sources. In this case, data (photocopies, books, posters, leaflets, manuals, or manuscripts) must be provided as evidence. Reporters may delve on the following concerns: necessity, beneficiality, practicability, socio-political acceptability, reliability, cost-efficiency, economic viability, independency, material availability, environmental sustainability, feasibility, aesthetic tolerability, technological adequacy, scientific integrity, and site specificity. Use of suitable visual aids is highly recommended. <br /><br />► DEBATE PROPER. 35-minute debate will follow after the 20-minute reporting where students from other groups are encouraged to throw questions, reactions, and clarifications concerning the report that must be answered by the group concerned. <br />During the debate and argumentation, the reporters are required to set their own rules so as not to sow confusion in the proceedings. No rule must be made to stop students from asking and arguing, or to bar anyone from giving at least a follow up question, if necessary. The subject teacher shall act as a semi-presiding officer and will only budge into the dialogue should the need arise. <br />It is the responsibility of the reporters concerned to ensure the decorum of the debate. Conversely, students are not allowed to use foul, vulgar, or non-sense words and actuations. Everybody must follow the ethical standards of argumentation and debate.<br /><br />► SEQUENCE OF REPORTING.<br /> <br />Group 1: Coal Fired Power Plant <br />Group 2: Oil Power Plant<br />Group 3: Natural Gas Power Plant<br />Group 4: Geothermal Power Plant<br />Group 5: Hydroelectric Power Plant<br />Group 6: Solar Power Plant<br />Group 7: Wind Power Plant<br />Group 8: Nuclear Power Plant <br /> <br /><br />► IMPORTANT NOTES. As a matter of procedure, the team leader of the report group shall ensure the flow of traffic during the debate and the equitable division of tasks among group members. Deliberations must not be monopolized by one person alone. To stress, the subject teacher may interfere anytime especially if the “conflicts” produced by the debate is “non-reconcilable,” off-tangent, or “absurd.”<br /><br />► ASSIGNMENT (PROBLEM SET 3). What must be done to alleviate the country’s energy concerns? How important are political will, sense of foresight, technology, environment, economics, scientific knowledge, research, and social responsibility in solving this problem? How important is energy to mankind as a whole? (This must be written in science notebook as a homework, but must be re-written in a yellow pad as Problem Set 4 to be passed December 15.)<br />► QUIZ WEIGHT. Students will be evaluated in the following areas:<br /><br />1. REPORTING AND ACTUAL DEBATE is Quiz 3-7 and is 170 points (See rubrics and rules below).<br />2. REPORT HANDOUT from the reporters must be distributed to all the other groups for their perusal immediately before the reporting starts. The format (which includes introduction, body of the report, conclusion and references) must be designed in reference to the four main objectives of this debate. This report handout is Quiz 3-8 and is 40 points. Criteria: Content, 50%, Organization of Ideas, 30%, Packaging and Page Design, 20%. Use long-sized bond paper. Late passers will be given a 40% deduction from his/her total score. Aside from the handouts, the reporter is also required to email his report to his classmates.<br />3. RESEARCH PAPER from the reporters must be submitted to the subject teacher the day before the reporting schedule. This research paper is Quiz 3-9 and is 50 points. It must start with a title page following the IP format, an introduction (which must discuss rationale and importance of the report), the body of the report, conclusion, and references. Criteria: Content, 50%, Organization of Ideas, 25%, Packaging and Page Design, 25%. Use short-sized bond paper and folder. Late passers will be given a 40% deduction from his/her total score. The reporter is also required to email his report to his classmates.<br />4. YOUTUBE DOCUMENTARY CLIP is required per group where they are supposed to conceptualize, direct, design and upload their report on their power plant. The intention is to put whatever media, information, and facilities that they have into a movie clip convincing the cyber audience that their source of energy is the best of all. This YouTube material is Quiz 3-10 and is 70 points. It must be uploaded on or before Friday, December 23. Criteria: Content and Style Used, 40%, Number of YouTube likes, 20%, Organization of Ideas, 20%, Originality and Overall Impact, 20%.<br />5. ESSAY TEST 1 is Quiz 3-11 and is 50 points. <br />6.

Each report is bound for 15-20 minutes to be conducted solely by the assigned student-reporter. He or she is to prepare all his/her visual aids, activities (e.g. quick seat work or group work if necessary), research paper, lesson plan, and handouts for the audience (like that of the Energy Debate style) to use or to keep.<br />Quizzes are set twice every week based on the lessons covered by the reporters. It is hereby stressed that the Reporter—who will assume the role of a teacher—must plan out, study on and research at his or her report well so as not to duplicate the discussion and strategy as previously done by the subject teacher in the early quarters. Innovation is a must. Use of visual aids is recommended. Hence, it is expected that in every class, students are suppose to expect an engaging, serious, intelligible, confident, well-prepared, and worthwhile presentation from the Reporter.<br />1. QUIZ 4-1. This reporting activity is a 120-point quiz and will also be included in the grading for Class Recitation. Reporters are to be graded using the following criteria: Mastery and Depth of Report: 50%, Organization and Flow of Ideas, 25%, and Delivery and Audience Participation, 25% points. Reporters may wear either his/her school uniform or any executive-science-teacher look get-up. In case of absence, the student will be reporting his topic immediately the day he/she reports to class. Unexcused absence will be given a 50% deduction from his total score.<br />2. Quiz 4-2. The reporter’s handouts that will be photocopied and given to his/her classmates and teacher during the reporting is a 40-point quiz. The objective of which is for the student to show that he/she understands thoroughly the topic by summarizing, designing, and packaging his/her topic report well. Criteria: Content, 50%, Organization of Ideas, 30%, Packaging and Page Design, 20%. Use long-sized bond paper. Late passers will be given a 40% deduction from his/her total score. Aside from the handouts, the reporter is also required to email his report to his classmates.<br />3. QUIZ 4-3. The reporter’s research paper that will be placed in a folder and passed to the subject teacher on the day before the reporting day is also a 50-point quiz. It has the same objective as that of the reporter’s handouts only that it must be more detailed. It must start with a title page following the IP format, an introduction (which must discuss rationale and importance of the report), the body of the report, conclusion, and references. Criteria: Content, 50%, Organization of Ideas, 25%, Packaging and Page Design, 25%. Use short-sized bond paper and folder. Late passers will be given a 40% deduction from his/her total score. The reporter is also required to email his report to his classmates.<br />4. QUIZ 4-4. The reporter’s lesson plan paper that will be passed to the subject teacher by all students on Wednesday, January 11, and is a 40-point quiz. It has the same objective and sequence as that of the student’s reporting only that it must follow the SECT lesson planning format. Criteria: Content, 30%, Organization of Ideas, 30%, Fidelity to the Lesson Plan Rules, Utility and Feasibility of Plan, 25%. Use short-sized bond paper. Late passers will be given a 30% deduction from his/her total score.<br /><br />REPORTERS’ NUMBERS:<br />No. 4 FAITH 4 INTEGRITY 4 FAITH<br /> <br />1 ALHAMBRA, Manuel Benjamin Lee B.

FOLLOW THE SCHOOL’S SCIENCE RESEARCH FORMAT.<br />2. DOUBLE CHECK YOUR GRAMMAR.<br />3. Margining: 1 ½ inches for left, and 1 inch for the rest of the sides.<br />4. Follow generic intro in all chapters. Visit p6withsirh.blogspot.com.<br />5. Use Arial 11 in all texts, including tables and graphs.<br />6. Except for Abstract and Resume, use 1 ½ spacing.<br />7. Left and right justify every page.<br />8. Avoid elongation of word or phrase spaces due to left-right justification. Try to use Enter command.<br />9. Avoid contractions (e.g. it’s, aren’t wouldn’t, herman’s). This is a formal paper; hence, words to be used must also connote formality and convention.<br />10. In all pages, always maximize paragraphing. Meaning, avoid overcrowding the paragraph. Use only one to three sentences a paragraph. Divide your ideas into paragraphs.<br />11. Except for the acknowledgement, the rest of the pages must be written in third person form.<br />12. Use “two (2)” not just “two” or “2.” For numbers more than nine (9), use figures instead.<br />13. Every time a source is said or noted, describe in detail what this source is all about. Do not just say “According to www.abc.com” or According to Lagon.” These sources must be described to prove that they are worth quoting or noting.<br />14. All pictures and graphs must be text-wrapped. All of them must also have captions Inquirer style. They must also follow the margin and must be placed in not-so-crowded spaces.<br />15. Tables and pictures must not be cut into pages. They must be printed or shown in “wholes.”<br />16. Everything must be left and right (full block) justified.<br />17. NO space in between paragraphs. Use “paragraph-line spacing” command to solve this perennial tech-neophyte problem. (Using mouse: ctrl A, Right click, paragraph, line spacing in zero—before and after—and single space)<br />18. Except for acknowledgement and recommendations, the rest must be written in past tense for the final paper.<br />19. Do not use all caps in table titles and classifications.<br /><br />Approval Sheet<br />20. Follow the Approval Sheet of the most recent passed Investigative Projects.<br />21. Final Passing of the Bound Paper and Final Tangible Output is Friday, December 2, 2011. Consultations at 4 p.m.-4:30 p.m. on per appointment basis. Bookbinding will only be allowed after the approval sheet is signed. Note that bookbinding may take three days on regular basis.<br /><br />Abstract<br />22. Abstract must provide an overview of the study’s purpose, method, results (conclusions) and implications (in that order). <br />23. Must only use at most two pages (one page is more recommended). It should follow the sequence of the investigation but must be written with utmost brevity and conciseness.<br />24. Everything said must be done in full summation (not cut and pasted, not “Chaptered”) and in past tense.<br />25. Discussions must be in paragraph form (avoid enumerating things).<br />26. Use single spacing (this single-spacing rule is only true for Abstract and Resume, the rest must be using 1 ½ spacing).<br />27. Note that people doing research check the Abstract first, and so this part of the paper must be given due time, depth, and effort.<br />28. Note that during the Exhibit and Defense Proper on January, 2011, the Abstract will be printed in bigger font (illustration board) for everybody to read and scrutinize.<br /><br />Acknowledgement<br />29. Written in first person basis.<br />30. Thank the teacher first, the science program of the school, the school itself, your adviser, then others in the middle, and lastly but most importantly, God Almighty. (Occupy the whole page, as much as possible)<br />31. Gratitude to be given in detail. Avoid generalized salutations or motherhood statements.<br />32. Use complete names (not just titles or surnames) of persons to thank with. If possible, explain their work or describe who they are in detail. <br /><br />Table of Contents<br />33. Be sure of the alignment and margining. Use tab in aligning the numbers.<br />34. Follow the format used by the most recent batch.<br /><br />Chapter 1 (Introduction)<br />35. All must be written in present tense (first and second quarters) and in past tense (for the third quarter), and in third person (including the rest of the chapters) basis.<br />36. Since the introduction to the study is a sort of a Rationale, it should answer the question, “how and why did the group decide to choose the topic?” This must be written in at most five paragraphs (the shorter but more concise the better).<br />37. Scope and Delimitation of the Study is divided into two: the first paragraph/s discussing the coverage of the study (here you may include the different concepts and devices covered, among others) and the second paragraph/s discussing the things that are not covered anymore by the study and the reasons why they are not included anymore. Limitations such as time, cooperation and effort are not acceptable. There might be other things that can cause slight inaccuracy or trouble in the investigation (and measurements) but initiatives to minimize the inaccuracy or trouble must be cited here.<br />38. Recheck hypotheses. There are still variables in some groups that are not measurable or are vaguely written.<br />39. All independent and dependent variables must be defined in the Definition of Terms.<br />40. All conceptual definitions must be taken from book references like dictionaries or encyclopedias. They must have endnotes.<br />41. Kindly give focus to the operational definition. Variables, especially the tangible ones, must be described in full using all senses possible. Also to be included are the points on how these variables are (to be) measured.<br /><br />Chapter 2 (Review of Related Literature)<br />42. Divide text into sub topics. Division may be based on hypothesis or any major subtopics covered in the study.<br />43. NEVER write anything here that the group does not understand (or does not use) at all. Avoid technical references, unless they are understandable and can be simplified.<br />44. Use formal third person writing (no “let us,” “we,” or “that you.”).<br />45. Be mindful of having a good closure or ending.<br />46. This is vital: Everything discussed here must be parallel to, related to or discussed again in Chapter 4 (Results and Analyses).<br />47. The more the related literatures and related studies, the better. Minimum of seven pages.<br />48. Big graphs, tables, or important pdf files (like that of important previous studies taken from the net) must be included in the appendix and not in Chapter 2.<br />49. In getting a reference, say: “According to Dr. Herman Lagon, lead scientist of the Department of Science and Technology, …” This is also true in website or book references.<br />50. References or interview from local experts on the field of study is highly encouraged.<br /><br />Chapter 3 (Methodology)<br />51. In second quarter, use present progressive tense for verbs since the investigation is still to be done. However, use past tense for verbs since the whole investigation was already done.<br />52. Make more detailed, specific, and blow-by-blow procedures. Write it as if you are making instructional guide to a grade six pupil.<br />53. Procedures must never be written like a cook book. Check the old investigative projects for reference.<br />54. Do not clog the procedures into one paragraph.<br />55. It would help if the textual procedures shall be accompanied by some graphics to facilitate better understanding.<br />56. Before the tables and graphs are presented, always make due introduction first (e.g. Below shows the table …).<br />57. Chapter 3 includes only the procedures and the materials. Do not insert here the analysis or results of the group yet.<br />58. Be conscious in giving the exact units, measurements and values, and in using the right tools, materials or instruments. Assume always that your instructions will be followed by younger students and so it must be as detailed, clear and idiot-friendly as possible. (To check, ask a younger student to read your procedures. If he or she can follow it, then it is ok. But if he or she can’t understand it well, then revise your work.)<br />59. Always remember that your chapter 3 is made for others to refer to it if they wish to do duplicate your experiment. If the instructions are unclear to them, then it defeats the purpose of verification of your study by other researchers.<br />60. Professional help is allowed in looking for the fittest statistical tool for the study. The more elegant the statistical tool used is, the better.<br /><br />Chapter 4 (Results and Analyses)<br />61. Specific experimentation (the procedure) is not supposed to be thoroughly described here. Instead, focus on the results and analyses of the data.<br />62. Remember the sequence per hypothesis: <br />1. Introduction of the hypothesis and table (“In Testing of Hypothesis 1 which states that, ‘xxxxxxxxxxxxxx,’ the following are the data gathered.”),<br />2. Table (all tables must be labeled or captioned based on the variables it describes),<br />3. Textual description of the table (“The table shows that…”),<br />4. Introduction of the line graph (“Below is the graph formed by the data described earlier.”)<br />5. Line Graph (you may add a bar graph if necessary; all graphs must be labeled or captioned based on the variables it describes),<br />6. Textual description of the graph which also includes the group’s analysis, inferences and assumptions (“The graph shows that…”)—this is one of the most important parts of Chapter 4,<br />7. Related Literatures (“The analysis showed conflicting {or similar) opinion/result with that of the same or similar experiment conducted by xxx last xxx which…”).<br />63. Not so important sub-tables and sub-graphs must be inserted as one of the Appendices (you may place “See Appendix xx for further details on this” or “Appendix xx shows…”).<br /><br />Chapter 5 (Conclusions and Recommendations)<br />64. Do not use “accepted” or “not accepted.” Rather, use “rejected” or “not rejected.” The reason for this is that due to some experimental limitations, we can only reject but not totally accept our hypotheses.<br />65. Like in Chapter 4, use inferences and assumptions (as much as possible) in every rejected or not rejected hypothesis in a more summarized way.<br />66. Never forget your general conclusion (that summarizes your conclusions) placed after the Conclusions.<br />67. Recommendations must focus not on “suntok sa buwan” things. Meaning, they must be real-life and can-be-done recommendations. This also covers recommendations to future investigators. It is nice to say that they must avoid procrastination and stuff but the central focus must be on what are the other investigations can they perform to further the search for knowledge in the study that you have now (e.g. innovations and other more creative, daring but plausible tests). <br /><br />Bibliography<br />68. Add more book references. Say 10 or more book references, 15 or more internet references, and 5 or more unpublished (investigative project or research) materials. In fact, the more your references are, the better.<br />69. Make sure that all your references must be cited or noted in any chapter, but primarily in chapters 2 or 4.<br />70. The more recent the references, the better. Do not use references that were published (copyright) more than 12 years ago.<br />71.

FOLLOW THE SCHOOL’S SCIENCE RESEARCH FORMAT.<br />2. DOUBLE CHECK YOUR GRAMMAR.<br />3. Margining: 1 ½ inches for left, and 1 inch for the rest of the sides.<br />4. Follow generic intro in all chapters. Visit p6withsirh.blogspot.com.<br />5. Use Arial 11 in all texts, including tables and graphs.<br />6. Except for Abstract and Resume, use 1 ½ spacing.<br />7. Left and right justify every page.<br />8. Avoid elongation of word or phrase spaces due to left-right justification. Try to use Enter command.<br />9. Avoid contractions (e.g. it’s, aren’t wouldn’t, herman’s). This is a formal paper; hence, words to be used must also connote formality and convention.<br />10. In all pages, always maximize paragraphing. Meaning, avoid overcrowding the paragraph. Use only one to three sentences a paragraph. Divide your ideas into paragraphs.<br />11. Except for the acknowledgement, the rest of the pages must be written in third person form.<br />12. Use “two (2)” not just “two” or “2.” For numbers more than nine (9), use figures instead.<br />13. Every time a source is said or noted, describe in detail what this source is all about. Do not just say “According to www.abc.com” or According to Lagon.” These sources must be described to prove that they are worth quoting or noting.<br />14. All pictures and graphs must be text-wrapped. All of them must also have captions Inquirer style. They must also follow the margin and must be placed in not-so-crowded spaces.<br />15. Tables and pictures must not be cut into pages. They must be printed or shown in “wholes.”<br />16. Everything must be left and right (full block) justified.<br />17. NO space in between paragraphs. Use “paragraph-line spacing” command to solve this perennial tech-neophyte problem. (Using mouse: ctrl A, Right click, paragraph, line spacing in zero—before and after—and single space)<br />18. Except for acknowledgement and recommendations, the rest must be written in past tense for the final paper.<br />19. Do not use all caps in table titles and classifications.<br /><br />Approval Sheet<br />20. Follow the Approval Sheet of the most recent passed Investigative Projects.<br />21. Final Passing of the Bound Paper and Final Tangible Output is Friday, December 2, 2011. Consultations at 4 p.m.-4:30 p.m. on per appointment basis. Bookbinding will only be allowed after the approval sheet is signed. Note that bookbinding may take three days on regular basis.<br /><br />Abstract<br />22. Abstract must provide an overview of the study’s purpose, method, results (conclusions) and implications (in that order). <br />23. Must only use at most two pages (one page is more recommended). It should follow the sequence of the investigation but must be written with utmost brevity and conciseness.<br />24. Everything said must be done in full summation (not cut and pasted, not “Chaptered”) and in past tense.<br />25. Discussions must be in paragraph form (avoid enumerating things).<br />26. Use single spacing (this single-spacing rule is only true for Abstract and Resume, the rest must be using 1 ½ spacing).<br />27. Note that people doing research check the Abstract first, and so this part of the paper must be given due time, depth, and effort.<br />28. Note that during the Exhibit and Defense Proper on January, 2011, the Abstract will be printed in bigger font (illustration board) for everybody to read and scrutinize.<br /><br />Acknowledgement<br />29. Written in first person basis.<br />30. Thank the teacher first, the science program of the school, the school itself, your adviser, then others in the middle, and lastly but most importantly, God Almighty. (Occupy the whole page, as much as possible)<br />31. Gratitude to be given in detail. Avoid generalized salutations or motherhood statements.<br />32. Use complete names (not just titles or surnames) of persons to thank with. If possible, explain their work or describe who they are in detail. <br /><br />Table of Contents<br />33. Be sure of the alignment and margining. Use tab in aligning the numbers.<br />34. Follow the format used by the most recent batch.<br /><br />Chapter 1 (Introduction)<br />35. All must be written in present tense (first and second quarters) and in past tense (for the third quarter), and in third person (including the rest of the chapters) basis.<br />36. Since the introduction to the study is a sort of a Rationale, it should answer the question, “how and why did the group decide to choose the topic?” This must be written in at most five paragraphs (the shorter but more concise the better).<br />37.

Final Judging Date (September 30)<br /><br /> Mechanics:<br />• Each section will be asked to design their bulletin boards for the Science Month Celebration under the theme:<br />SEED TODAY, SAVE TOMORROW<br />• Only the whiteboard at the back portion of the classroom will be used by the class for the Bulletin Board Design. The left cork board will be used as the Science Bulletin Area (where students are to place some latest Science information plus current news and trends) and the other side of the cork board will be spared for other class announcements.<br />• Students are given eight (8) days to design their section’s bulletin board.<br />• The bulletin board will be one of the seat work-recitations of each class in Science in the second quarter. Student’s individual participation will be checked and verified.<br /><br /> For the white board area (Main Bulletin):<br />• The design of the bulletin board must be primarily aligned on this year’s theme: “Seed Today, Save Tomorrow” <br />• Design must be student friendly, informative, interactive, artistic, entertaining, festive, and attractive but must never be a distraction in class for normal class proceedings.<br />• Since this year’s focus is on environmental awareness, buying of costly materials for the boards is highly discouraged. <br /><br /> For the left cork board area (Science Bulletin):<br />• This is where the section will post current, interesting Science news/issues.<br />• It must also have sort of “background designs” for aesthetic purposes.<br /><br />• Criteria for judging:<br />Originality, 30%; Adherence to the Celebration Theme, 30%; Creativity, 30%; Impact, 10%; Total, 100%<br /><br />3. Science Quiz Bowl (Battle of the Science Wiz 2011)<br />a.

There will be three to four members per group; 12 groups in a section; 36 competing groups from three sections all-in-all. Members shall be grouped according to their first grading period’s physics grades.<br />2. This Bridge Design Contest is graded (Quiz 2-7) for 60 points. The top 1 group will receive a perfect score of 60 points, followed by the second placing group at 59 points, and so on, making the last placing (36th) group bag only 25 points. Extra points will be given to designs that are extraordinary or novel. <br />3. Using only glue guns, rubber bands, and popsicle sticks, each group will conceptualize and construct a bridge of their design choice. The contraption must be designed to carry the greatest amount of load in the least amount of bridge materials used.<br />4. After a given time for conceptualization and construction, all bridges are to be passed and presented to the class in one assigned long table at the same time.<br />5. Each bridge will be weighed in using the digital weighing scale first before it is to be placed by an assigned student on top of the two vertical supports (probably laboratory chairs) that are 60 centimeters away from each other.<br />6. A steel bar shall be placed across the middle of the resting bridge. Then rope shall be attached to both ends of the bar. This rope will be fastened to a tray where the weights shall be placed one by one until the bridge gives way or fails. <br />7. A failed bridge is operationally defined as a contraption that: 1. fails to make it in the deadline given, 2. shatters, breaks, splinters, or crushes due to the load given, 3. has bent so much that makes the tray touch the floor, 4. has slipped out of the support due to shortness of bridge length, shear or twisting caused by the load (or due to erratic design).<br />8. Judging will be based on the H Factor which is computed as:<br />H Factor = Maximum load capacity in grams / Bridge’s mass in grams<br /><br />Assignment:<br />Using the bridge contest experience, write in your physics journal your realization/s on the importance of physics concepts to society, especially in the area of civil works e.g. roads, bridges, drainages, and buildings. Furthermore, reflect on the image of the bridge, load and supports representing self, life’s challenges, and God, respectively.<br /><br />Note: <br />This activity is tailor-made for Ateneo de Illoilo students of Engr.

All fourth year students will be given the chance to join this contest for it will be given to them as a 10-point quiz plus it will be included as one of the components for recitation in the Second Quarter. <br />2. The proposed theme can be written in English, Filipino, or Hiligaynon using a clean sheet of yellow pad. <br />3. The proposed theme must revolve around the idea of Science (knowledge) and Environment as this year’s celebration will focus on environmental awareness and how Science plays a big role in taking care of the environment. <br />4. There is no specified length for the theme, but it would be better if it is brief, novel (original), concise, easy to remember, and direct to the point. <br />5. An explanation (at least 5 sentences) of the proposed theme is also required. <br />6. There is no limit in the number of entries to be submitted. The more entries, the higher the possibility of having extra points. More so, chosen winners will be guaranteed of extra points. <br />7. The entry will be passed to the physics teacher through the class’ physics beadle on or before 4 p.m. of Friday, September 2. <br />8. Top 10 winners will be chosen among the 700 or more entries passed by all students of Ateneo de Iloilo. Judging will be based on the criteria below. <br /> <br />Criteria for judging: <br />Originality - 30% <br />Relevance to the Celebration - 40% <br />Impact - 30% <br />Total: 100% <br /><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3988717207032365808-990902687909533564?l=p6withsirh.blogspot.com' alt='' /></div>Engr.

Can you answer him convincingly? How? Are you really convinced of your reply to him? Why? <br />• Physics is quantitative in nature. It deals with things that are measurable. Likewise, it puts experimentation as its main arbiter. What does this mean to you especially in finding for what is true, good, real, and beautiful? Will this subject and the laws and principles it carries help you appreciate more God’s creation? <br />• How will physics in particular (and science in general) help me understand my role as a student and future leader of your generation in this fast-changing world? <br />• Why do you think that there is a need to humanize the “immortals of physics?” How will this help you be inspired to learn and do physics more? <br />• They say that physics is amoral. It is like a knife. Its use depends on where one holds it—either in the handle or in the blade. What does this mean to you as far as issues like cloning, nuclear war, cyber hacking, carbon emission, and mutation, among others, are concerned? <br />• If your life is an experiment, what would be your controlled (independent) variables? How about your strenuous variables? Dependent (manipulated) variables? How important is the identification of these variables in dealing with your daily get-up-and-goes?’ <br />• How do vectors make sense in the real world? Why do we need to study it? <br />•Man ultimately determines the uses, misuses, and non uses of science and technology. Comment on this. <br />•Physics speaks mathematics and measures things—all to explain the natural world to benefit mankind. Comment on this. <br /> <br />UNIT 2 (MECHANICS) ‘PROBLEM SET’ ON ATENEO DE ILOILO HIGH PHYSICS <br />(Deadline: Monday, August 22, to Bep Chavez-Faith, Danela Anacan-Integrity, and Ruod Ariete-Justice, on or before 4:20 p.m.) <br />ANSWER THE FOLLOWING REFLECTION QUESTIONS BRIEFLY, CONCISELY, CLEARLY, AND NEATLY. <br /> <br /> <br />• Why do I need to know the things that cause objects to move? How will this help me understand the dynamics of nature? <br />• Is it possible for an object to move even without being forced <br />to move? Why? How is this related to my life as a student? <br />• Every Atenean is an athlete. And athletes, some say, need to know the physics of their sport. Why is that so? <br />• How important is the concept of balancing to objects? How is this correlated to striking a balance in your life? Will stability be possible in an imbalanced world? <br />• When Newton saw the apple to fall, he eventually formulated the laws of motion. To you, what does this have to say with being a student of science? <br />• Why do we fall? What causes things to fall? What has this to do with Newton’s Apple? <br />• Why is it important to understand the rudiments of mechanics in the area of road safety? <br />•How related is a falling body from ocean tides, law of acceleration, and universal law of gravitation? How is this associated with the scientific maxim that “all things are regular and predictable?” <br />• Comment on this: “Everything in the universe changes and moves.” How is this related to human life? <br />• Physics concepts are essential in the area of engineering. Why is this so? <br />• Why is it that many economists, politicians, and scientists are saying that an engineering course option to our high school graduate is a wise thing to consider? <br /> <br />NEVER EVER WASTE TIME AND SPACE <br />Engr.

Lagon<br /> <br />P-Noy’s government gives full support to the K-12 Education Plan. As part of his Educational Reform Program, the administration believes that adding more years to basic education in the Philippines could help solve the problem of unemployment, keep up with global standards, and help Filipino students to have more time to choose the career that best suits their skills.<br />K-12 Education specifically means adding two more years in the secondary level plus kindergarten in pre-school. Such plan is not that easy for it also concerns the financial capacity of parents, the number of schools and classrooms, the number of teachers, and even the availability of books and other school supplies.<br />If this ambitious multi-billion-peso plan becomes successful, then the Philippine education system can become more competitive among other countries around the world. It is worthy to note that only the Philippines and one country in Africa or in South Asia I believe have 10-year basic education cycle. Most countries have 12 years before their students take any college course. Some more progressive countries even have 14 years for pre-college education.<br />However, it won't work if the needed elements to make it work aren't present.<br />Such elements, as stated above, include the adequate supply of schools, classrooms, chairs, manpower (teachers, administrators, and staff), books, laboratory equipment, instructional aids, utilities, community support, curriculum approaches, etc. If the government could allot a bigger budget to educational needs, then we could be one-step ahead towards the success of the K-12 program.<br />Furthermore, parents (especially those who belong in the poor sector) should be properly informed and motivated of the advantages of the K-12 Education Plan. This is very important since parents play a major role in providing the child's school allowances, supplies, and fees for other school projects and activities. Add to that the support of parents towards their children in terms of guidance and teaching.<br />Once this succeeds, it is best hoped that Filipino students would be more literate, skilled, and competitive to be able to find jobs more easily and contribute to the country's pride as well as the country's economy.<br />To note more, the K12 Basic Education Program is the Standard Education Program throughout the world. This has already been implemented on most countries and nations, especially on those which are economically progressive and has high values for human skills and efficiency.<br />As an educator, I fully understand the government’s desire to raise the quality of education here in the Philippines. Each year, the need for highly competitive graduates continues to grow as the demand for high paying jobs spread across the globe. Each year, ironically, our school produce is becoming more incompetent, unskilled, and illiterate. Sadly, this is proven by the different educational and labor surveys, diagnostic and achievement tests.<br />While this proposed K-12 education program may help us achieve that (which obviously could take many years), there are concerns in the education sector that need the more immediate response and attention of the government.<br />Some say that extending the number of years in school will not directly affect nor influence the quality of education because it would only mean adding more budget for more teachers and classrooms. After all, we’re for quality and not quantity, they say.<br />I am not sure if they are correct. What I am sure of is that the present 10-year system does not work and we need to do something about it; that K12 aims for a quality and relevant education; that good education defines good citizenship and national progress.<br />So, until the critics have a more concrete and not a motherhood-statement alternative, I will peg my hope to the K12 plan and support it in any way possible. Besides, the P-Noy government is serious in fulfilling it. What’s more, 98% of the world’s population says K12 works. Numbers and evidences don’t lie.<br />* * *<br />Engr.
