Aim: To learn about a saturated solution and how to make crystals

Crystal video

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)

In groups of three you will make three different types of crystals and compare the results.

Borax Crystals

Borax Crystals time-lapse video

Ratio; 3 Tablespoons Borax per 1/2 cup water

Materials

1)borax

2)cup

3)pen

4) water 

5) stick

6) peg

7) pimp cleaners

Process

Step 1: get a cup and stick 

Step 2: get a pan

Step 3: writ sugar, salt, borax on each cups 

Step 4: put hot water in the borax cup 

Step 5: put borax in the cup and mix with warm water.

step 6  use peg to tilt the pimp cleaners to a star then use the peg to tit the pimp cleaners

Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1)sugar

2)cup

3)pen

4) water 

5) stick

Process

Step 1: get a cup and a stick 

Step 2: get a pan 

Step 3: write sugar on

Step 4: put warm water in the cup 

Step 5: put 6 sugar in the cup 

Step 6: use the stick  to mix the warm water with sugar

step 7: put wool on the stick then put one the cup.

Salt Crystals

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1)salt 

2)cup

3)pen

4) water 

5) stick

6)wool

Process

Step 1: get a cup and a stick 

Step 2: get a pan  

Step 3: write salt on

Step 4:  put warm water in the cup 

Step 5:  put 2 spoon salt in the cup 

Step 6: put wool on the stick then put on the cup

Findings

Describe your crystals in the table below.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax		medium cube-shape	hard
Sugar	cube-shape	smell	hard
Salt		medium cube -shape	hard

What crystals worked out best and why?:

borax crystal is the best crystal because it was bigger and also is so fun.

Conclusion:

Making crystal was so fun because you can see what going on when you finding the crystal. also making crystal was need some time to see the crystal.

How is salt formed
How is sugar formed
How are snowflakes made 

Explain how the following crystals are formed:

Type	Explanation
Salt	when the water evaporates from the solution, then the Na and Ci bond together,  then the molecules from the water evaporates bond together, every time when the molecule forms, the shape of the molecule are the same.
Sugar	when the water evaporates, then the solution becomes saturated and sugar, then molecules will keep come out of the solution and also collect on the seed crystals on the string, the rock candy crystals grow molecule by molecule.
Snowflakes	when the cold water droplets freeze on pollen or dust particles in the sky then snowflakes begin to form when extremely, snowflakes  have six arms.
