Using the catapult, the handle of the spoon is pushed down, shooting the jelly bean through the air. Middle school students: According to Newtons’s Law’s of Motion, force has an equal and opposite reaction.Next Generation Science Standards: PS2-A, PS2-B, PS2-C When constructing the catapult, the distance from the top of the spoon to where the cork is on the handle should be varied to show how rotational force comes into play. The amount of force is directly related to the distance the jelly bean will travel. Force has an equal and opposite reaction. Grade 4 – 6 students: Force can define as a push or a pull.The change in leverage should make it easier or harder to shoot the jelly bean far. Students should also try and measure the distance traveled, and try and vary the distance the cork of the catapult is from the top of the spoon. More force will send the jelly bean farther. The amount of force varies the distance that the jelly bean will travel. Using the catapult, the handle of the spoon is pushed down forcing the jelly bean to be shot through the air. These actions put objects into motion, with an equal amount of force as the initial push or pull. PK – grade 3 students: Force is a push or a pull.Does the amount of force used to launch the jelly bean have a relationship to how far it goes?.Will the Jelly bean go farther with more force placed on the handle of the spoon?.Why does the distance change when you put more or less force on the handle of the spoon?.Then place jelly bean on spoon, and launch by pressing down on bottom of handle. Start by wrapping spoon mid- handle in rubber band, then attaching to wine cork in crossed manner, as can be seen below.Ģ.Display Board for Recording Students Distances.
