EXAMPLE 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.

Borax Crystals

Ratio; 3 Tablespoons Borax per 1/2 cup water

Materials

1) A cup or a glass

2) Pipe cleaner

3) Borax

4) Popsicle stick

5) String
6) Warm water
7) Spoon

Process

Step 1: Grab a cup or glass

Step 2: Put 3 tables spoons of borax and 1/2 cups 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 your pipecleaner, tie this to the string 
Step 7: Put your star into the borax and water solution

Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1) 4 spoons of sugar

2) String

3) Cup 

4) Warm water

5) Popsicle stick 

Process

Step 1: Get your cup

Step 2: Measure four tablespoons of sugar into your cup

Step 3: Add a half cup of warm water to your sugar

Step 4: Mix the solution with the popsicle stick 

Step 5: Tie a string to the middle of the popsicle stick

Step 6: Dip the string into the solution, rest the stick across the cup

Salt Crystals

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1) Popsicle stick

2) Salt

3) Warm water

4) String

5) Cup

Process

Step 1: Grab a cup

Step 2: Put 4 tablespoons of salt in the cup

Step 3: Add warm water to your salt

Step 4: Mix the solution

Step 5: Tie string to popsicle stick

Step 6: Dip the string into the solution, rest the stick across the cup
