Station 1

Pick up bicycle wheel and hold the handles with your hands. Have some one spin the wheel.  Stand on the green science source platform and turn the wheel horizontally. In what direction does the bicycle wheel rotate? In what direction do you spin? Why? Draw a picture with force labels and arrows showing the direction of motion. Identify the action and reaction pair.

Station 2

Students line up and take turns stepping on a skateboard. As they step off, what happens? Draw a picture with force labels and arrows showing the direction of motion. Identify the action and reaction pair.

Station 3

Place some marbles evenly under a piece of cardboard. Put a pull back car that has been pulled back on the cardboard. Release the car and observe. What happens? Draw a picture with force labels and arrows showing the direction of motion. Identify the action and reaction pair.

Station 4

Two students hook spring scales together. One tries to pull with a force of 5 newtons while the other tries to pull with a force of 10 newtons. What happens? Why?

Station 5

Push two identical dynamic carts together so that their spring bumpers are compressed. Release the carts on a flat surface. Why do the carts accelerate away from on another at the same rate? Add a mass to one of the carts and repeat the experiment. What happens? Why?
