  1. Mission Possible B - 2013

  2. Safety • Students must be supervised at all times. • Use the score sheet as a guide.

  3. Construction

  4. Construction

  5. TSL 1. Drop a quarter from above device. (4a) 2. Quarter triggers mousetrap which pulls string. 3. Pulling string operates pulley system w/ IMA>2 lifting object 10 cm. (4f + SM) 4. Object knocks 2nd object off ledge, pulls stringpulling egg apart. (4b) 5. Contents of egg fall and trip spring. (4e) 6. Spring raises container which trips and pours sand into higher container (4j) 7. Container falls and operates 2 levers w/ IMA=10. (4g + self explain IMA) 8. Object lifted by levers pushes another object off ledge. Falling object works pulleys which lift platform completing final task. Platform is lifted by 50 cm. (4m + self meas. 50 cm.)

  6. Set-up Time • 30 minutes • Plan ahead! • Everyone has a job! • Allow time for testing, but • Don’t overdo it! • Don’t run down your batteries! • Make sure it is ready to run! • Relax!

  7. Self-Measure-Distances Tasks 4c 4d 4f 4h 4i 4l

  8. Self-Explain I.M.A.s Tasks 4f and 4g

  9. Drop a Quarter to initiate an action

  10. Timing Starts When? • The quarter is first dropped.

  11. Timing Stops When? Top of device

  12. 4b.

  13. 4c.

  14. 4d.

  15. 4e.

  16. 4f.

  17. 4g.

  18. 4h.

  19. 4i.

  20. 4j. What does “higher” mean?

  21. 4k.

  22. 4l. The Special Task > 10 cm. Limit = 45° 20 points + Mass in grams/50 (max=100 pts.) + Vertical distance mass is raised (in whole cm.)

  23. 4m. The Final Task NO Requirements: 1. Describes sizes and requirements for objects; 2. Describes requirements for the platform & objects can not be heldin any way; 3. Describes positioning and stance of objects on platform; 4. During the run, only items allowed on the platform are those at the start. YES

  24. Whole Seconds What is a “whole” second? 59.2 59.9 60.1 60.5 60.8 60.999

  25. Penalties Touches = Adjustments = Restarts = 15 points each time

  26. Penalties TIME 1 point per whole second over the “ideal” time

  27. Serious Offenses The penalty is disqualification • Stalling-not immediately trying to re-start the device when the action stops • Interrupting the device when it is working to gain an advantage in time points

  28. Outside Help

  29. Breaking Ties 1. Fewest penalty points; 2. Most sand timer points; 3. Closest to ideal time. Mission Possible Scoreboard Home Visitor 753 753

  30. Tiers & More Tears 1. No violations (penalties are OK) 2. Competition violations 3. Construction violations 4. Late impound Unsafe device Disqualification

  31. So which is it?
