Snowball Catapult

A catapult is a ballistic device used to launch a projectile a great distance without the aid of explosive devices. Using the materials provided, design and build your own catapult.  Here is a “How to” video.

Now experiment! Who can launch the cotton ball to a specific target?


  • Play Civiballs.  Cut the chains to launch a series of events. The journey of the civiballs is filled with catapults, ramps, moving platforms and more!
  • Use your catapult to lob various objects. Measure the distance for each object. Let’s apply Newton’s 2nd Law to our own results. Watch here.
  • Use S.C.A.M.P.E.R. to design a new catapult.  Use materials from home to create a catapult.  We will have a catapult contest on Friday, February 15th!
