2. Instructions for using this template. Remember this is Jeopardy, so where I have written “Answer” this is the prompt the students will see, and where I have “Question” should be the student’s response. To enter your questions and answers, click once on the text on the slide, then highlight and just type over what’s there to replace it. If you hit Delete or Backspace, it sometimes makes the text box disappear. When clicking on the slide to move to the next appropriate slide, be sure you see the hand, not the arrow. (If you put your cursor over a text box, it will be an arrow and WILL NOT take you to the right location.)

3. Choose a category. You will be given the answer. You must give the correct question. Click to begin.

7. What is a lever?

8. This machine allows objects to travel distances more easily.

9. What is a wheel and axle?

10. This object pushes two surfaces apart.

11. What is a wedge?

12. This machine makes lifting heavy objects easier by sliding them up a surface.

13. What is an inclined plane?

14. This machine allows objects to be raised or lowered by pulling a cord.

15. What is a pulley?

16. This machine reduces the amount of force needed to lift an object by dividing the weight or load.

17. What is a pulley?

18. This object uses less force to lift objects by using a fulcrum.

19. What is a lever?

20. This machine uses less effort to allow objects to travel far distances.

21. What is a wheel and axle?

22. This machine allows you to use less force to separate objects.

23. What is a wedge?

24. This machine allows objects to be raised with less effort over a longer distance.

25. What is an inclined plane?

26. In a two gear system, if you turn the first gear clockwise, what direction will the 2 nd gear turn?

43. What is a wheel and axle?

44. Name the simple machine pictured below.

45. What is an inclined plane?

46. Any action that alters an objects state of rest or uniform motion in a straight line.

47. What is force?

48. The force that occurs when one object or surface rubs against another.

49. What is friction?

50. The speed at which an object travels.

51. What is velocity?

52. When the speed of an object increases.

53. What is acceleration?

54. When an object is at rest, it stays at rest until a force acts on it.

55. What is inertia?
