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)Cup

2)String

3)Popsicle stick 

4)Water

5)Pipe cleaner

Process

Step 1: Take 3 tablespoons borax 

Step 2: put in on a cup

Step 3: pour hot water

Step 4: mix it

Step 5: Get a Pipe cleaner and twist it in the middle to form star

Step 6: then tie it on the string and attach the other side of the string on the pop sickle stick.

Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1)Cup

2)Water

3)String

4)Popsicle stick

5)Spoon

Process

Step 1: Get a cup 

Step 2: get a string 

Step 3: get sugar

Step 4: pour hot water 

Step 5: mix it

Step 6: tie the string on the pop sickle stick

Salt Crystals

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1)Cup
2)Water

3)String

4)Popsicle stick

5)Spoon

Process

Step 1: Get a cup 

Step 2: get a string 

Step 3: get sugar

Step 4: pour hot water 

Step 5: mix it

Step 6: tie the string on the pop sickle stick.

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	small	weak
Sugar	Frosty	medium	brittle
Salt	Cubic	big	hard

What crystals worked out best and why?: I think the sugar one, because sugar is more likely a crystal. 
Conclusion: I found that if you use cold water it will not work so next time Ill try to put hot water.

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

explain how the following crystals are formed?

They formed because when a sugar is on the water they stick together. They like stick to the string , when it is not in the water they don't stick/bunch up.

Type	Number of sides	2 examples	Image
Flourite (also called fluorspar) is the mineral form of calcium fluoride, CaF2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon.	8
Wulfenite is a lead molybdate mineral with the formula PbMoO4. It can be most often found as thin tabular crystals with a bright orange-red to yellow-orange color, sometimes brown, although the color can be highly variable.	8
Tanzanite is a trade name that was first used by Tiffany and Company for gem-quality specimens of the mineral zoisite with a blue color. Tiffany could have sold the material under the mineralogical name of "blue zoisite," but they thought the name "tanzanite" would stimulate customer interest and be easier to market.	8
orthombicof or denoting a crystal system or three-dimensional geometrical arrangement having three unequal axes at right angles.	8
Hexagonal 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"	12
Monoclinic of or denoting a crystal system or three-dimensional geometrical arrangement having three unequal axes of which one is at right angles to the other two.	12
TriclinicIin 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.	16

Type
Salt	Sea water, pond, sun, evaporates water.
Sugar	Chop it up, squish/roll, juice heat evaporate water and sugar crystallised.
Snowflakes	Dust, water freezes to the dust, more water and wind will freeze the dust.
