Crystals

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.

Step 3: Stir the borax and the water together with your stick
Step 4: Once you have done that tie a piece of string on your stick
Step 5: Then tie a pipe cleaner to the string and put that in the borax
Step 6: wait for a few days to see what happens to the liquid

Sugar Crystals

Grow your own Sugar Crystals
