Aim: To learn about a saturated solution and how to make crystals

Definition of solution: 

A liquid mixture, when something is dissolved into a liquid (eg: sugar in water) 

Definition of saturated: 

Having or holding as much as can be absorbed of something (when no more sugar or borax can be dissolved into the water)

In groups of three you will make three different types of crystals and compare the results.
