We placed the bundle of 5 sticks at the very bottom of the “V” shape and secured it with the final rubber band. Next, we pried open the 2 sticks to make a “V” shape. They stacked the remaining 2 sticks and bound them with a single rubber band on the very edge of one end. This would act as the base and fulcrum – the point at which the lever will pivot. 1 small cup (We used the top to a juice container.)įirst, I had each kiddo stack 5 craft sticks on top of each other and then I helped them bind them on each end with a rubber band.7 craft sticks (wide craft sticks are easier for little hands to hold.).To make the pumpkin catapult, I quickly gathered a few supplies: Balancing the candy pumpkin on the end of the handle, I simply hit the spoon end with my hand to send the pumpkin flying through the air. In the most basic terms, a catapult is a simple machine used to launch an object or projectile without the use of explosives.īefore building our catapult, I showed my kiddos an example of a simple catapult using a spoon. Launching candy across the house? What’s not to love?! After your little engineers build theirs, hop on over for more science fun with our Epic STEM Challenges! After explaining to my 3 and 5 year-old what a catapult was, I simply challenged them to build one that would launch candy pumpkins. STEM activities (Science Technology Engineering and Math) are always a hit with my kiddos, but this engineering activity had the whole family wanting to get in on the action.
