2. Student Entrance • Pick up 4 papers • Catalyst, Walking Directions (Distance),Physics Reference Sheet, Homework • Begin Catalyst • Silent activity • Respond to questions on the CATALYST sheet • Use complete sentences • Will be turned in to Mrs. Larkin

3. Agenda • 10 min: Catalyst (Exam Reflection) • 25 min: Activity (Distance Activity, Displacement Activity) • 25 min: Notes (Dist. vs. Disp., Scalar vs. Vector) • 7 min: Break • 8 min: Practice (Distance vs. Displacement) • 10 min: Notes (Speed vs. Velocity) • 13 min: Practice (Speed) • 2 min: Homework (Speed vs. Velocity)

4. Collect Catalyst

5. Announcements • If you were absent Monday/Tuesday, I need your labs! • Students must take exam by Thursday at 4:00 PM • Otherwise you will receive a ZERO in the gradebook • Period 1-3 • Aidan Mobley • Brie Quinones • Period 2-4 • Robbie Schraer • Period 6-8 • Bianca Covarrubias • Jasson Montenegro • SiriKhalsa • Period 9-11 • Lauren Lopez

6. Walking Directions (Distance) • Follow the directions on the worksheet • Stay in the courtyard • Everyone should do their own steps and turns • 5 minute activity • Be quick and efficient • Focus on what you are doing, not on others

7. Think-Pair-Share • Mrs. Larkin’s Example

8. Think-Pair-Share • Think: • Recall your journey • Map it out on the dots as Mrs. Larkin did • Pair: • Compare journeys with your group members • Share: • 3 people called at random to draw their journeys

9. Walking Directions (Displacement) • NEW DIRECTIONS! • Follow the directions on the worksheet • Stay in the courtyard • Everyone should do their own steps and turns • 5 minute activity • Be quick and efficient • Focus on what you are doing, not on others

10. Think-Pair-Share • Think: • Recall your journey • Map it out on the dots as Mrs. Larkin did • Pair: • Compare journeys with your group members • Share: • 3 people called at random to draw their journeys

11. Think-Pair-Share • Mrs. Larkin’s Example

12. Collect BOTH Walking Directions • All that you should have left • White homework worksheet • Pink physics equation sheet

13. Distance vs. Displacement • Notebook

14. Distance vs. Displacement • Draw small Venn Diagram (about size of hand) • Talk to your group: • 2 similarities for distance & displacement • 1 difference for distance & displacement

15. Distance vs. Displacement • Distance: how much the object has moved • Displacement: how far object is from its starting point

16. Distance vs. Displacement • Notebook

17. Scalar vs. Vector • Scalar: measurement , no direction • To represent a scalar, use a letter • Distance: d • Time: t • Speed: v

18. Scalar vs. Vector • Vector: measurement WITH direction • To represent a vector, use a letter & arrow • Displacement: x or y • Velocity: v • Acceleration: a

19. Scalar vs. Vector • Why x or y for displacement? +y (vertical) FALLING DOWN ALONG THE GROUND -x (horizontal) +X • Memory Trick: • H is before V, just • like X is before Y -y

20. BREAK • 7 minutes • Must be seated, otherwise TARDY

21. Practice • Whiteboards • 60 seconds: group name • Work with your group • Do not lose markers • Try to not show your answers to other groups!

22. Practice • Mrs. Larkin runs forward 10 feet. She then turns around and runs back 7 feet. What distance did she run?

23. Practice • Mrs. Larkin runs forward 13 feet. She then turns around and runs back 6 feet. What displacement did she run?

24. Practice • Shadow runs 3 meters east, then 2 meters north, then 3 meters west. What distance did she run?

25. Practice • Shadow runs 4 inches north, then 5 inches east, then 4 inches south. What displacement did she run?

26. Practice • Ms. Parsons drives to and from Da Vinci Design, which is located 5 miles from her house. • A. What is the total distance she drives every day? • B. What is her displacement every day?

27. Practice • La Luz runs a complete circle around the classroom. What displacement did she run? (Use feet)

28. Practice • La Luz and Shadow are racing each other around a circular track. The track is 500 meters around and 159 meters across. La Luz gets tired and stops halfway around. Shadow finishes the race. • A. Who has the greater displacement? • B. By how many meters? 500 meters around 159 metersacross

29. Practice • La Luz and Shadow are racing each other around a circular track. The track is 500 meters around and 159 meters across. La Luz gets tired and stops halfway around. Shadow finishes the race. • A. Who ran the greater distance? • B. By how many meters? 500 meters around 159 metersacross

30. Figuring Out an Equation • Here are some units for speed: • Miles per hour (mi/h) • Kilometers per hour (km/h) • Meters per second (m/s) • Feet per second (ft/s) • What do all the numeratorshave in common? • What do all the denominatorshave in common?

31. Speed vs. Velocity • Notebook

32. Speed vs. Velocity Speed (SCALAR) is the total distancetraveled in a certain amount of time.

33. Speed vs. Velocity Velocity (VECTOR) is the displacement (change in position) that occurs in a certain amount of time.
