  1. Projectile Launcher Mini Project 10/22/13

  2. Bellwork • If you are only given time (t) and range (dx) how can you find vy?

  3. Projectile Launcher Mini Project 10/22/13

  4. Objective: • Objective: To launch an unmodified cotton ball to a target that is 1.50 m away

  5. file folder 1 piece of cardboard 5 index cards 5 paper clips 2 rubber bands 50 cm of string 200 g mass masking tape scissors ruler Materials:

  6. Requirements • Free standing and movable • Only can use materials given • Masking tape (adhesive use sparingly) • Scissors and ruler (for construction only) • Will be launched from the floor • Group number and names • NO trigger needed

  7. Design Phase • On a piece of paper draw or sketch your proposed mini project with a 5 sentence description (1 per group). • When your group has a design show Mr. Z. to collect your materials. • Materials: 5 index cards, file folder, cardboard, 200 g mass, 5 paper clips, 2 rubber bands, 50 cm of string, masking tape (adhesive use sparingly), scissors & ruler (for construction only), and nothing else.

  8. Construction Phase • Free standing and movable • Only can use materials given • Masking tape (adhesive use sparingly) • Scissors and ruler (for construction only) • Will be launched from the floor • Group number and names • NO trigger needed • You will have three tries to hit the target • Hint: Your firing a cotton ball!

  9. Testing Phase: Tomorrow • Distance is measured from where it lands from the target

  10. Clean-Up Phase • Return any unused materials AND masking tape, scissors & ruler to side counter • Place launcher in the cabnet and make sure lab area is clean

  11. Projectile Launcher Mini Project (Day 2) 10/23/13

  12. Bellwork • Who are the targets for the projectile projects? • Mr. Z. will check off the homework

  13. Testing • Your group will be given 1 cotton ball to test with at your lab bench (lengthwise is 1.50 m) • You will have 15 minutes to make any adjustments • You will be given 1 new cotton ball for the final test

  14. Data Collecting • Mr. Z. will measure the distances • The “On-Deck” group will be given stopwatches to time how long the ball in in the air for • You need to collect data for every group even your own

  15. Clean-Up • Masses, scissors, tape, rulers, etc. back to the cart • Stopwatch back in the bin • Launcher in the trash or take home

  16. Projectile Launcher Mini Project (Day 3) 10/24/13

  17. Bellwork • How far is “CDO bear” (the target) going to placed from the launching zone? • 15.0 m (49.2 ft)

  18. Projectile Project • Have to hit the target from the air, NOT rolling along the ground • 50.0 cm3, before launch • If you are over then it will be launched at the end • You may set it manually, • after it is locked into place • then only mechanical power

  19. Calendar • Today – Finish the Mini-Project • Fri. 10/25 – Work day for the project or review • Mon. 10/28 – Launching Day • Wed. 10/30 – Review is due • Thur. 10/31 – Projectile Test Part 1: Multiple Choice and Short Answer • Fri. 11/1 – Projectile Test Part 2: Projectile Problems • Mon. 11/4 – Projectile Project Calculations and Analysis due (New due date!)

  20. Projectile Mini-ProjectCalculations: (In T-Charts) • Using your groups data (or another groups) for each trial (3 total) find: a) Find the tennis ball’s horizontal velocity b) Find the tennis ball’s vertical velocity c) Find the tennis ball’s max height d) Find the tennis ball’s resultant velocity

  21. Conclusion: (In paragraph form) • What was your furthest distance? • How close were you from the target? • How successful was your design? • What problems did you encounter, during construction and launching? • What would you do differently if you did this again? • How did this activity help you with the project?

  22. Make-Up Assignment • Research five past designs to launch projectiles. (These can include non-mechanical designs.) • Write a page (handwritten) in paragraph form that includes: • Five different designs that you have researched. • The history of the designs. • What is the purpose of these designs? • Provide a summary on how these helped with your pro.

  23. Reflection Phase 2012 version: (In complete sentences.) • 1) What was your furthest distance? • 2) How close was this to your prediction? • 3) What worked well for your design? • 4) What problems did you encounter? • 5) What would you do differently if you did this again? • 6) How did this activity help you with the project?
