In my monthly club for K-2nd graders we focused on rockets! There is a lot that you can teach about rockets but oh so much FUN you can have with rockets too!! First the group built their rockets from these materials:
1 Paper Towel Roll
2 pieces of construction paper
After the rockets were put together as shown in this video below we then had teams that held string tightly so we could race two rockets at one time.
So the steps that we did were:
1.) Make your own rocket by using construction paper, masking tape, and adding straw to the top
2.) Have four volunteers to hold two lengths of string about 5 feet long
3.) Have two rockets go at one time on two different lengths of string by blowing up two balloons and attaching them to the rocket along the bottoms with masking tape (only after blown up).
4.) Release both balloons at same time so that the rockets can race!
We talked about Newton’s third law to tie in the science of the rockets.
Newton’s third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object
