  1. Tuesday, December 15, 2009- PHYSICS • Warmup: What is a pinhole camera? How does it work? • Presentations: Chapter 17- 18- 19 wave labs (up to 4 ppl per group, 200 pts., was assigned last Weds.) • Chapter 17 problems assigned, due Thursday 12/17: Chapter 17 problems assigned, due Thursday 12/17: P.503#1-5; P.507 #1-10; P.512 #1-8; P.521 #1-9; P.527- 528 #1-36; P.529 #1-6. ( was assigned on Fri.12/11) • Coming soon: index of refraction labs with laser pointers: bring yours if you have one (10 pts. Extra credit per day) TOMORROW, THURS, and FRIDAY.

  2. Tuesday December 15, 2009CHEMISTRY • Warmup: What is an anion? • Memorize p.171 table 1 for quiz on Weds. • SCIENCE FAIR DISCUSSION AND PREPARATION: DISPLAY BOARD LAYOUTS, REPORT FORMATS: BEGIN ROUGH DRAFTS!!!! • Complete procedure and 50% of r.draft for a glowstick today. • ACT Prep for prizes.0p0

  5. Tuesday, December 15, 2009 • Warmup: What was the topic of the page 94 – 95 lab? • Grade Printouts MAKEUP WORK DUE Thurs. Dec.17 • Pages 94 – 95 lab. WRITEUP – ANSWERED QUESTIONS- DUE TOMORROW. • HOMEWORK DUE THURS. P.93 #1-2

  6. Judges’ Tally Sheet: How is your science fair project graded? • Student’s name is clearly identified • The question the project seeks to answer is clear • The hypothesis is clearly stated • The variable(s) is/are clearly stated • The procedures are clear, complete, and relevant to the hypothesis • Data or observations records are well- illustrated by graphs, tables, photos, etc. • The conclusion is consistent with the data and clearly refers to the original hypothesis • The display is neatly organized and is appealing to the eye • The written explanation clearly shows an understanding of the project and the ability to extend beyond the project • The written portion of the project (including the display) demonstrates a command of written language, utilizing proper grammar and punctuation

  7. More grading: 5 pts. Each: • Originality and creativity • Quality of work and organization • Accuracy of information • Knowledge and extension • Display (elements of the scientific method are identified and displayed using charts, graphs, pictures, etc.)

  8. Rough draft is due Fri. Jan. 8 Computer Lab: Jan.7… 200 points- 50 ec by Fri.12/18 • Name, date, teacher (Mrs. Gall), title • Question, purpose, hypothesis • Controls, variables • Materials, procedure • Data (numbers, charts), results (full sentence descriptions) • Conclusion (hypothesis supported or refuted, errors, what you learned) • Bibliography (minimum 3 sources, at least one book)

  9. TODAY- WHEN YOU FINISH P.165 #1-13: • PLEASE FILL IN THE SCIENCE FAIR PRACTICE BOARD HEADINGS AND AS MUCH INFORMATION AS YOU CAN. • THANK YOU!
