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)

Borax Crystals

Borax Crystals time lapse video

Ratio; 3 Tablespoons Borax per 1/2 cup water

Materials

1) Pipe cleaners

2) String

3) Regs

4)Borax

5)Cups

Process

Step 1:Shape pipe cleaners into star shapes.

Step 2:Hang star on a peg.

Step 3:Mate up borax solution.

Step 4:Label your cup.

Step 5: Pour three spoons of borax.

Step 6: Pour half a cup of cold water into the borax cup.

Step 7: Steer the borax and the water so it can mix together.

Step 8: Pour three spoons of salt in the salt cup.

Step 9: Tip half a cup of water into the salt cup.

Step 10: Steer the water and the salt to mix them.

Step 11: Pour four spoons of sugar into the sugar cup.

Step 12: Tip half a cup of water into the sugar to mix them.

Step 13: Wet the star.
