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 1: Get a cup or a glass.
Step 2: Put 3 tablespoons of borax and 1/2 cups of water. 
Step 3: Add ingredients to the cup.
Step 4: Mix it together with your Popsicle stick.
Step 5: Tie your string to your Popsicle stick.
Step 6: Make a star with the pipe cleaner, tie it to the string.
Step 7: Put your star into your borax and water solution. 

Sugar Crystals

Grow your own Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water
Materials

1) Cup or glass.
2) Warm water
3) Spoon
4) Popsicle stick
5) String

Process

Step 1: Get a cup or glass.
