Saturated crystals

I 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.

Borax Crystals

 M

Ratio; 3 Tablespoons Borax per 1/2 cup water

Materials

1) borax 

2) hot water 

3) a cup

4) pipe cleaners

5) stick

Process

Step 1: get 3 tea spoons of borax

Step 2:Add hot water

Step 3:mix with stick for ten minutes

Step 4:make a star shape with a wire

Step 5:use a peg to hold the star but beneath the water

Step 6:put the Star beneath the water

Sugar Crystals

G

Ratio: 1 cup sugar to 1/2 cup water

Materials

1) sugar

2) hot water 

3) stick

4) string

5) a cup

Process

Step 1: get sugar 

Step 2: add hot water

Step 3: stir

Step 4: add string to stick

Step 5: put stick over cup so string goes into water

Salt Crystals
