Home made 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) pip cleaners

2) string 

3) cup 

4) hot water

5) borax
6) stick

Process

Step 1: grab a polyester cup.

Step 2: put 4 teaspoon of borax.  

Step 3: then put hot water. 

Step 4: then stir the borax in to the hot water.

Step 5: tie the string to the stick

Step 6: tie the pipe cleaner to the string
Step 7: Place the string into the cup

Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1) sugar. 

2) polyester cup

3) teaspoon

4) hot water 

5) string
6) stick

Process

Step 1: get a  polyester cup 

Step 2: put sugar in the cup

Step 3: put hot water in the cup

Step 4: stir the sugar in with the water

Step 5: tie the string to the stick 

Step 6: set it in the water

Salt Crystals

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1) salt

2) polyester cup

3) teaspoon

4) hot water 

5) string
6) stick

Process

Step 1: put salt in polyester cup.

Step 2: then put hot water in the cup.

Step 3: stir it to together.

Step 4: tie the string to the stick. 

Step 5: put the string in the water.

Step 6: then let it set.

Findings

Describe your crystals in the table below.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	Snow flake,  Frosty.	Madinm.	Brittle.
Sugar	No crystals formed.	Small.	Weak
Salt	Frosty.	Small.	Hard.

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	house a box with a pont
Monoclinic Definition:	9	diamond a banker
Orthombic Definition:	5	rectangle
Trigonal Definition:	9	long house.
Hexagonal Definition:	8	tall box tall circle
Cubic Definition:	5	cube Square
Tetragonal Definition:	9	gem from a gam

Explain how the following crystals are formed?

Type
Salt	Soa water, pond, sun, evaporates water and the turns into salt crystal.
Sugar	Sugar cane, chop it up, roll it in to juice, heat elaporate water and then you have a sager crystal.
Snowflakes	Dust,water freezer to dust,  more water freezer to it.
