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.
Assembling the Sample Chain Reaction Device
Your teacher may instruct you to assemble and test the sample unpowered Chain Reaction
Device next.
