Crystal Science

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) Borax
2) Cup
3) Spoon
4) Water
5) Pipe Cleaners
6) Popsicle Stick
7) String

Process

Step 1: Grab a cup
Step 2: Put 3 tablespoons of borax into a cup and 1/2 cups of water
Step 3: add them together
Step 4: mix until all mixed in
Step 5: fold pipe cleaners into a snowflake
Step 6:put snowflake on to the Popsicle stick

Sugar Crystals

Grow your own Sugar Crystals

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

1) Sugar
2) Cup
3) Spoon
4) Warm water
5) Popsicle
6) String

Process

Step 1: Add Some sugar
Step 2: Add 1/2 a cup of water
Step 3: Mix together with a Popsicle 
Step 4: Tie String to the Popsicle  
Step 5: Put Popsicle in the water
Step 6: wait


Salt Crystals

Ratio: 4 Tablespoons salt to 1/2 cup water
Materials

1) Salt
2) Cup
3) Spoon
4) Popsicle Stick
5) water

Process

Step 1: Add 4 Tablespoons of salt to the cup
Step 2: add 1/2 a cup of of warm water
Step 3: mix with a Popsicle stick
Step 4: Tie the string to the middle of the Popsicle Stick
Step 5: Put the stick in the water
Step 6: wait

Explain how the following crystals are formed?



Type

Salt
When people make salt they get it from the sea and then it goes into little ponds then the sun evaporates it then it turns into salt

Sugar
They Cut down The sugar cane and then they squish it until flat they separate the juice from the fibre then they heat it and get syrup then they use sugar to make sugar.

Snowflakes
The Snowflakes Fall down from the sky as dust and the the water molecules join the dust to sort of turn into a snowflake but then a little bit more happens
