8. Force and Motion: Does the height of a ramp affect the distance a toy car will roll? Does the height from which a rubber ball is released affect the height that it bounces? Does the surface of the ground affect how far a ball will roll? Heat and Temperature: Does the color of water affect the time it takes to freeze? Does the kind of water affect how quickly it will evaporate? Does the depth of the water affect its evaporation rate? Does the temperature of water affect its evaporation rate? Does the kind of soil (sand, gravel, clay) affect its temperature change in the sun? Does the temperature of a tennis ball affect how high it bounces when dropped? Plants : Does the circumference of a pumpkin affect the number of seeds inside? Does the diameter of an apple affect the number of seeds inside? Does classical music affect the height of tomato plants? Does the amount of fertilizer affect the height that grass will grow?

9. Non-Vertebrate Animals: Does the type of surface affect the distance a meal worm travels? Does playing rock music affect the distance that a meal worm travels? Does the moisture of the surface affect the distance that an earthworm travels? Earth/Space and Environmental: Does salt affect the freezing rate of water? Does the rotation of the earth (time of the day) affect the length of a shadow? Does the kind of water (fresh or salt) affect how long it takes an ice cube to melt?

10. When I change the amount a plant is watered, what will happen to the height of a plant.

34. D ATA : F ILL IN AS YOU COMPLETE EACH EXPERIMENT. Experiment Data for first variable: Example (1 st variable - tennis ball) Example: #1 tennis ball bounced 10 cm, #2 tennis ball bounced 11 cm. Trial # 1 Trial # 2 Trial # 3 Trial # 4 Trial # 5 Trial # 6 Trial # 7 Trial # 8 Trial # 9 Trial # 10

35. D ATA : F ILL IN AS YOU COMPLETE EACH EXPERIMENT. Experiment Data for second variable: Example (2 nd variable - golf ball) Example: #1 golf ball bounced 21 cm, #2 golf ball bounced 23 cm. Trial # 1 Trial # 2 Trial # 3 Trial # 4 Trial # 5 Trial # 6 Trial # 7 Trial # 8 Trial # 9 Trial # 10

36. E XPLANATION Explain if the data supports your selected prediction. (If your data does not support your prediction, don’t worry. Just explain why.) Example: The data supports my prediction. The golf ball on average bounced higher than the tennis ball.
