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) Water

2) Borax

3) Cup

4) Spoon 

5) Popsicle stick
6) String
7) Pipe cleaner

Process

Step 1: Get a cup

Step 2: Get a spoon

Step 3: Get the Borax

Step 4: Put it in the cup

Step 5: Put some water in 

Step 6: Mix it around 

Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1) Spoon

2) Cup

3) Stick

4) Sugar

5) Water

Process

Step 1: Get a cup

Step 2: Get some Sugar

Step 3: Get some water

Step 4: Put sugar in the cup

Step 5: And then put some warm water in

Step 6: And then mix it up

Salt Crystals

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1) Cup or glass

2) Salt

3) Warm water

4) Spoon

5) Popsicle stick

Process

Step 1: Get a cup

Step 2: Get warm water

Step 3: Put salt in the cup

Step 4: Put warm water in

Step 5: Tie the string on to the the Popsicle stick

Step 6: And then wait for about a day

Findings
That the sugar and the salt done the same but the the other one did not do the same as the salt and the sugar because the sugar and salt done nothing.

Describe your crystals in the table below.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	Icy star looking	big	hard
Sugar	nothing	nothing	Soft
Salt	nothing	small	Hard

What crystals worked out best and why?: Borax because it had the star tied onto the rope

Conclusion: The best one was the borax

CRYSTAL TYPES

AIM: TO LOOK AT THE 7 DIFFERENT TYPES OF CRYSTALS

Salt Crystals

Sugar Crystals

Borax Crystals

7 different crystal shapes

The 7 types of crystals

Type	Number of sides	2 examples	Image
Triclinic Definition:	6
Monoclinic Definition:	8
Orthombic Definition:	6
Trigonal Definition:	10
Hexagonal Definition:	8
Cubic Definition:	6
Tetragonal Definition:	12

Explain how the following crystals are formed?

Type
Salt	Sea water Pond Sun Evaporate water Salt
Sugar	Sugar cane Cop it up Squish/roll roll to get the the juice Heat Evaporate the water Sugar crystallize
Snowflakes	Dust Water freezes to dust More water freezes to it
