Crazy 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) borax

2)cup

3)Popsicle stick 

4)a little rope

5)hot water

Process

Step 1: get the cup.

Step 2: put borax, sugar or salt

Step 3:put hot water in it.

Step 4: get you Popsicle stick.

Step 5: get the line and tie it in your Popsicle stick.

Step 6: put it in the cup and wait for a couple of days 

Sugar Crystals

Materials

1) sugar

2)cup

3)Popsicle stick 

4)a little rope

5)hot water

Process

Step 1: get the cup.

Step 2: put sugar, baking soda or salt

Step 3:put hot water in it.

Step 4: get you Popsicle stick.

Step 5: get the line and tie it in your Popsicle stick.

Step 6: put it in the cup and wait for a couple of days 

salt crystals

Materials

1) salt

2)cup

3)Popsicle stick 

4)a little rope

5)hot water

Process

Step 1: get the cup.

Step 2: put salt, borax or sugar

Step 3:put hot water in it.

Step 4: get you Popsicle stick.

Step 5: get the line and tie it in your Popsicle stick.

Step 6: put it in the cup and wait for a couple of days 

Crystal Type	Shape (Describe the shape)	Size (of individual cry stals)	Hardness (Crumbly to Rock Hard)
Borax		2cm	harder than the sugar.
Sugar	no shape	no size	it break when you bite it.
Salt	cube	5cm	hardest of them all when you bite it its quite 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:In crystallography, the triclinic (or anorthic) crystal system is one of the 7 crystal systems. A crystal system is described by three basis vectors. In the triclinic system, the crystal is described by vectors of unequal length, as in the orthorhombic system.	7
Monoclinic Definition: In crystallography, the monoclinic crystal system is one of the 7 crystal systems. A crystal system is described by three vectors. In the monoclinicsystem, the crystal is described by vectors of unequal lengths, as in the orthorhombic system. They form a rectangular prism with a parallelogram as its base.	10
Orthombic Definition: of or denoting a crystal system or three-dimensional geometrical arrangement having three unequal axes at right angles.	6
Trigonal Definition: of or denoting a crystal system or three-dimensional geometrical arrangement having three equal axes separated by equal angles that are not right angles.	10
Hexagonal Definition:of or denoting a crystal system or three-dimensional geometrical arrangement having three axes of equal length separated by 60° and a fourth axis of a different length at right angles to these. "a hexagonal close-packed crystal structure"	8
Cubic Definition: the cube it shaped like a square.	6
Tetragonal Definition: In crystallography, the tetragonal crystal system is one of the 7 crystal systems. Tetragonal crystal lattices result from stretching a cubic lattice along one of its lattice vectors, so that the cube becomes a rectangular prism with a square base (a by a) and height (c, which is different from a).	12

Explain how the following crystals are formed?

Type
Salt	seawater, pond,sun,evaporates water, salt
Sugar	sugar can, clean it up, squish roll, juice heater, evaporate the water,  the sugar crystallizes
Snowflakes	dust, water freezes to the dust, more water freezes it.
