How to make crystals

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

Crystal video

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.

Borax Crystals

Ratio; 3 Tablespoons Borax per 1/2 cup water

Materials

1)borax

2)water

3) cup

4)stick

5)

Process

Step 1: Put your hot water in the cup.

Step 2: Then put your borax in the cup.

Step 3: Next we stored the hot water and the borax together.

Step 4: Then we put the stick on the cup
