Crystals Chemistry

Aim: To learn about a saturated solution and how to make crystals
Definition of the 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)

Conclusion.
we had to make crystals. First, we had brainstormed of 'what are the kitchen equipment' that we can make crystals out of. I had a group which is David, Khush and me we were given each cup. our teacher put our cup with warm water and a teaspoon of sugar, salt and borax then we mix it.

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) Pipe Cleaner
2) String
3) Pegs
4) Borax
5) Cup
6) Steering stick
Process

Step 1: Shape pipe cleaners into a star shape.
Step 2: Hang star on a peg.
Step 3: Makeup a borax solution. 
Step 4: Label the cup.
Step 5: Put 3 spoon of borax.
Step 6: Steer it for 5 minutes.
Step 7: Get the star shape pipe cleaner and pg it inside above the water.

Sugar Crystals

Grow your own Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1) String 
2) Peg
3) Cup
4) Sugar
5) Pipe cleaner 
6) Steering stick

Process

Step 1: Make up a sugar solution. 
Step 2: Label the cup.
Step 3: Put six spoon of sugar.
Step 4: Steer it for 5 minutes.
Step 7: Get a string and tie it on the stick.
Step 8: Put it on the cup.

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1) Pipe cleaner
2) Salt
3) Cup
4) Peg
5) String
6) Steering stick

Process

Step 1: Make up a salt solution. 
Step 2: Label the cup.
Step 3: Put 3 spoon of salt.
Step 4: Steer it for 15 minutes. 
Step 5: Get a String then tie it in the stick.
Step 6: Put on the cup.

After watching the videos as a class, explain how the following crystals are formed:


Type
Explanation
Salt

The sea water was set in the sun and it evaporates then the sea water and the salt was separated.   

Sugar
The sugar cane is cut into small pieces and crush into juice then remove the tiny bit of wood in the sugar juice then turned into a crystal.


Snowflakes
A little water falling from a sky then the water freeze into a snowflake.
