Make Your Own Catapult
Today for science I wanted to do an activity to finish off our study of machines. So I looked at putting together models of complex machines (cars, planes, etc.), or at putting together our own working machine...the catapult.
We decided on a catapult that was easy to put together & only required items that we could find around the house. Any project that doesn't cost money is fine by me! So I found a design that uses office supplies & within 30 minutes we had a working catapult.
All you need for this are pencils, rubber bands, tape & a bottle cap (from bottled water). For more information on how to make this & other cool projects, go to http://www.stormthecastle.com/
From their homepage look on the left hand side under "Projects" & you will see a link for "Make a catapult".
