2. In 15 seconds, how long should the standard pendulum system swing?

3. 12 times

4. Name 3 variables in a pendulum system.

5. 1.Length of pendulum 2.Release position 3.Mass at the end of the pendulum

6. Both relationships between the length of a pendulum system and the number of swings

7. -The longer the pendulum the less swings -The shorter the pendulum greater the number of swings

8. Any motion or activity that repeats itself

9. Cycle

10. The greatest amount of fluid a container can hold

11. Capacity

12. What variables may affect the number of passengers a boat can hold? (list 3)

13. 1.capacity 2.placement of pennies 3.type of water

14. What unit of measurement is used for capacity?

15. Milliliters (mL)

16. The moane flies. CAPACITY #PASSENGERS#PASSENGERS What does this trend line tell you?

17. The greater the capacity, the more passengers a boat can hold.

18. What tool can you use to help you make predictions?

19. A two-coordinate graph

20. The number of lives the standard lifeboat saved

21. 38 lives

22. I am a system

23. A set of objects which work together to perform a specific function.

24. Step 5 of Scientific Inquiry

25. Analyze results and form a conclusion

26. What is the relationship between the number of passengers on a plane and the distance it flies?

27. The greater the number of passengers the less the distance.

28. The term used to describe anything that might effect the outcome of an experiment.

29. Variable

30. Which of the following would improve the accuracy of an experiment: -using smaller units of measurement -using larger units of measurement.

31. using smaller units of measurement

32. Why is it necessary to create a standard?

33. As a basis for comparison to see how the variable tested affects the results

34. What should you do to a catapult to make the mass fly the farthest distance?

35. Increase the angle of the catapult Move the catapult closer Use a smaller mass

36. What flipper angle should make a mass go the farthest distance?

37. 40 degrees

38. What variable should be graphed on the x-axis?

39. Independent

40. An experiment in which only one variable is changed and the outcome is compared to a standard.

41. Controlled experiment

42. The variable that you find out by doing a controlled experiment?

43. Dependent variable

44. What you know before doing an experiment

45. Independent variable

46. The basic procedure used in a controlled experiment, before changing any of the variables

47. Standard

48. Changes of equal amounts

49. Increments

50. Why is it good to repeat an experiment with multiple trials?

51. To have better accuracy
