Force and Motion

After talking about forces, pushes and pulls, the kindergarten class was given the opportunity to apply this knowledge.  So, in STEM lab, we assembled marshmallow launchers.  Each student built two launchers.  These were constructed from a paper or styrofoam cup and a balloon.  Once completed, we took them outside to test them out.  If given the chance to redesign the students concluded that the paper cup worked better because they were sturdier, and that you should only cut off a little of your balloon so it stayed in place better.  They also thought that smaller marshmallows would travel farther when launched than the larger ones I provided.
