Use a rubber band to attach a plastic spoon on one. You’ve already got your two popsicle sticks banded together. If the coin / pompom keeps sliding off the end of the bar, you can glue a lid to the end of the bar so you have a “bucket” to put your coin / pompom into.Īfter they’ve had a good time with this one, you can take this simple design to the next level by creating a spoon catapult. Put your pompon (or coin) on the raised end, then use your finger to press down and release. Then slide a pencil (or three craft sticks bundled together) between the sticks until it pushes up against the rubber band. Now, take two popsicle sticks: Use a rubber band to fasten them together at one end. But, they’ll soon discover that this is a weak catapult – we can get a lot better launch by evolving it. Like try a large spoon balanced over a rolling pin, or a ruler balanced over a marker. You can also play with this idea – use a bigger fulcrum – use a longer lever. This is an easy depiction of the simple machine concept of levers (learn more about Levers here.) Hit the high end of the stick, the object launches. Put an object (your load) onto the end that’s laying on the table. pompom or mini marshmallow or coins)įirst, take a popsicle stick (the bar of your lever), balance it over a pencil (your fulcrum). Supplies needed: pencil, popsicle / craft sticks, rubber bands, a plastic spoon, an object to launch (e.g. I want to present a simple series of catapults that show the evolution of an idea.
