What is a Chain Reaction Device?

A Chain Reaction Device is a complex machine that performs a very simple task in a very complicated way. A Chain Reaction is a series of events so related to each other that each event triggers the next event.

In this unit you will use a series of simple machine and/or pendulum assemblies to create Chain Reaction Devices. Each individual simple machine/pendulum assembly is known as a Stage of the overall device. Students will also build and/or design at least one Trigger Mechanism to activate the operation/chain reaction of their device(s) in this unit.
