1. Monday PS Yellow Book Lab

2. Tests Some are graded, not all Hand back Wednesday-ish

3. Essential Question How do we describe what happens in a collision in terms of Newton’s Laws of Motion

4. P14 in yellow book Describe the forces pushing/pulling on Jaime’s during collision. Draw a free-body diagram

5. Free Body Diagram of Jaime Upward force of seat Weight Friction and seat belt Forward force of seat

6. P14 Why is she having x-rays and an EKG What is the use of an X-ray? What is the use of an EKG?

7. Use of X-rays

8. Use of EKG Echocardiograms

9. MRI Magnetic Resonance Imagery

10. The rest of the class Will be spent in groups creating clay crash dummies to be used for observation Goals: To connect the laws of motion to auto accidents To understand the result of using different types of seat-belts in crashes

11. Car Crash Lab Each person is responsible for completion of pages 15-22 Write the predictions BEFORE Do and record the observations Then Answer any questions in book

12. Task #1 Create and record motion of body/head on car

13. Task #2 Create, record motion of the heads on bus

14. Warning Any horseplay or making of inappropriate anatomical parts for the clay figures will result in you spending the rest of the time in room 240 today and a zero for the missing pages of work

15. Group Selection 3-5 people per group My choice

16. Materials that need to be acquired by each group Ramp Wooden Car Clay Scissors 3-4 straws 4-6 world history textbooks (by back window) Ribbon (pick up from teacher when needed Same on the floor for ramp, start ramp from a seat

17. Crash Simulation II Jamie goes hurtling down the ramp into a book barrier Barrier = 4-6 books 1-2 feet away from bottom of ramp. No seat belt

18. Crash Simulation #3 Jamie goes hurtling down the ramp into a book barricade with different kinds of seat-belts Only 2 width’s of seat-belts available: –Wire –Ribbon Do first part with shoulder harness Do the second part without shoulder harness

19. Last page (22) 3 simulations –Try simulation 1 between 2 people in group –Discuss and answer other 2 simulations

20. Discussions of results Going over answers to the questions

21. Comparing forces in contact Two people leaning against each other Neither is moving How do the forces each exerts on the other compare?

22. Sit #2 Fast moving object crashing into stationary object What are the action and reaction forces? How do they compare?

23. Objects in motion What are the action and reaction forces? How do they compare?

24. Comparison of action-reaction forces in different situations Make predictions for each situations on page 23-25

25. P27 Write the third law in the scroll Answer the question below the scroll

26. P29 On the moon, the acceleration due to gravity is 1.7m/s 2 Complete part 1 and part 2 Inertia is measured by mass

27. P30 Finding the weight of an object Weight = ___________ x ___________

28. Weight = mass X acceleration due to gravity Complete part IV on page 30

29. Homework in Yellow Book Page 35-37 problems 3-8

30. Sum up How do the forces exerted on the car and bus from the collision compare? How does the mass of the car compare to the mass of the bus? Which object (Bus, Car) will accelerate more because of the applied force from the accident? How does acceleration relate to people getting hurt on the car or bus? Knowing about action-reaction forces, why was there more damage done to the car?

31. P45 Write all three laws of Newton

32. Seat Belts Did Jaime’s seatbelt help or harm her? Would seatbelts have helped or harmed the students on the bus for this accident? Are there other types of accidents with school buses that would have changed your answer in the above question?

33. The Seatbelt issue Read pg 46-51 (includes some articles on the issue of seat-belts on buses Answer the first 3 questions on page 46 Use the internet to see if any district or states requires school buses to have seatbelts– get specifics Determine if other buses are required to have seatbelts (greyhound…)

34. Seatbelt Position Paper One-two pages Typewritten, (handwritten will lose points) Provide some evidence for both sides of the argument Use the laws of Newton correctly to back up evidence May bring up other issues (Security, cost…) in addition to argue your position Grammar, Paragraph structure will count

35. Due Next Thursday October 19
