1. STUDY GUIDE

2. An experiment in which one and only one variable is changed at a time

3. Any motion or activity that repeats itself

4. A mass hanging from a fixed point, free to swing back and forth when put in motion

5. The basic procedure in any experiment before changing any of the variables; what the results of a controlled experiment are compared to.

6. A graph that shows the outcome of a series of experiments when a variable is changed by steps.

7. The factor or condition that might change the outcome of an experiment

8. The maximum volume of fluid a container can hold

9. The variable that is determined after the experiment is completed; graphed on the “y” axis.

10. The variable that is known before the experiment begins; graphed on the “x” axis.

11. A set of objects that are related in some way and can be isolated for study.

12. Change one thing at a time

13. Length of the pendulum Mass at the end of the pendulum Release position

14. The longer the pendulum, the fewer swings it will make in 15 seconds.

15. Shorten the pendulum

16. Capacity of the lifeboat Arrangement of the pennies Size of the boat

17. The greater the capacity, the more pennies it will hold before sinking.

18. Angle of the flight line Starting position Number of winds on the propeller Mass (number of pax)

19. The more mass of a plane, the less distance it will fly.

20. Angle of launch Length of the flipper stick Number of spacers (pennies) Mass of the object getting flipped

21. The greater the angle, the farther the object will travel.

22. To increase its accuracy
