Science Project Experiment Catapult Kit (S.P.E.C.K.) Description

The Ultimate Science Project Experiments Catapult Kit (S.P.E.C.K.) It's fully adjustable, multi-configurable and repeatable.

This outstanding model is manufactured from top-quality fine-grain birch plywood. It is stronger, more dimensionally stable and a lot less expensive than similar kits made from natural wood.

No glue required! All parts can be assembled with rubber bands for fast and speedy modifications. Rubber bands and wooden projectiles are included!
In one configuration it's a counterweight trebuchet. You can shift the counterweight or adjust the main fulcrum to change the lever ratio of the throwing arm. In another configuration it's a class-one lever catapult. Also adjustable for multiple lever-ratio options. Or change it to a class-three lever catapult.

Try it with wheels or without, use a sling or try it with a cupped arm. Which is more effective? Which is easier to use?

All in all, there are more than 400 different configurations and tuning options possible with this kit. Suitable for hundreds of experiments and learning opportunities.

What you get:
All the parts needed to assemble every configuration of this kit, wooden projectiles, and a fully illustrated 18 page manual.

The completed frame is 14.5 inches long, 7 inches wide and 11 inches tall. The arm measures 20.25 inches long with multiple axle and power attachment points.

What you can learn:
This kit provides a real world, hands on example of many aspects of basic physics. It exposes the student to concepts of mechanical advantage, levers, gravity and energy, to name a few. It can demonstrate the storage and conversion of potential energy to kinetic energy through levers, and it is equipped with optional wheels, to demonstrate conservation of momentum. All in all, the concepts of efficiency, power and work can be demonstrated and applied.
