Introduction:
A catapult is any mechanical device
used to throw a projectile a great distance; particularly various
types of ancient and medieval siege engines. Construction of a
catapult will familiarize students with mechanical machines and how
they work.
This project is called My First
Catapult because often students use it as the first step toward
developing more advanced and more creative models.
The catapult appears to have been
invented in 399 BC in the city of Syracuse during the reign of the
tyrant Dionysios I. Originally, "catapult" referred to a
dart-thrower, while "ballista" referred to a stone-thrower, but the
two terms swapped meaning sometime in the fourth century AD.
If you want to make your first
catapult as your school project or educational activity, you may
consider this simple model and save time by ordering a kit.
Wood parts needed to
construct this catapult are pre-cut and ready to use in a
kit. Pre-cut parts can save you time and eliminate problems
associated with cutting wood.
In addition to the wood
parts and the rubber band that come in the kit, you will
also need some white glue and a piece of sand paper. You may
also need sealer, paint and brush to finish or decorate your
catapult model. |

Launching (Testing your
catapult)
We recommend that you only launch
soft objects from the catapult. Load a soft object into the
projectile cradle; we suggest a small marshmallow. You can
experiment by raising the front of the catapult. When you adjust the
elevation of the front or back of the catapult, you will see how it
affects the distance that the launched object travels.
Detail instructions for this
catapult project are available online.
If you don't
have this kit, you can order it now! It is
available both as a single pack and class pack.
