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)
Borax Crystals
In groups of three you will make three different types of crystals and compare the results.
Ratio; 3 Tablespoons Borax per 1/2 cup water
Materials
1) Cup/glass
2) Pipe cleaner
3)borax
4) sting
5)Popsicle stick
6) Warm Water
7) Spoon
Process
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
Materials
1) Cup or glass.
2) Warm water
3) Spoon
4) Popsicle stick
5) String
Process
Step 1: Get a cup or glass.
Step 2: Put 1 cup of sugar and 1/2 a cup of warm water in the cup.
Step 3: Add ingredients into cup.
Step 4: Mix them together with a Popsicle stick.
Step 5: When it dissolved, put 4 tablespoons in your borax and water solution.
Step 6: Tie your string to your Popsicle stick and put it in the borax and water solution.
Salt Crystals
Ratio: 4 Tablespoons salt to 1/2 cup water
Materials
1) Cup
2) Salt
3) Warm Water
4) String
5) Popsicle stick
Process
Step 1: Get cup
Step 2: Put 4 tablespoons of salt in the cup.
Step 3: Put 1/2 cups of warm water in with the salt.
Step 4: Mix it with Popsicle stick until the salt dissolved.
Step 5: Tie string on the Popsicle stick.
Step 6: Put Popsicle stick in the borax and water solution.
