Crystal

Hi,

This week in Science we have been doing an experiment. So in Science have been doing an experiment about making a crystal in science. In science we got into groups of 3 and me and my partner we were only 2 so we have work really fast so that's why we can finish the third one because there is three types of crystal were going to. After we have done our process making the experiment after 1 day we got to see the crystal and our one has a crystal under the rope and it shape like a snow flake but after a few minutes when we have look at it again it melted. So if you want to make crystal read the process here below I hope you like it.

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) Borax

3) Warm water

4) Popsicle stick

5) Rope

Process

Step 1: Grab a cup

Step 2: Pour 3 table spoon of borax

Step 3: Pour some warm water

Step 4: Get a Popsicle stick and a rope

Step 5: Then tie the rope on the Popsicle stick

Step 6: Then only put the rope in the cup not the Popsicle stick

Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1)  Cup 

2) Sugar

3) Warm water

4) Rope 

5) Popsicle stick

Process

Step 1: First grab a cup

Step 2: Pour a 1 cup of sugar

Step 3: Then pour the warm water

Step 4: Get a Popsicle stick and a rope

Step 5: Then tie the rope in the Popsicle stick

Step 6: After that put the rope in the water

Salt Crystals

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1) Cup 

2) Salt

3) Warm water

4) Rope 

5) Popsicle stick

Process

Step 1: Grab a cup

Step 2: Pour a 4 table spoon of salt 

Step 3: Then pour the warm water in the cup 

Step 4: Fourth one you grab some rope and a Popsicle stick

Step 5: Then Tie the rope in the Popsicle stick

Step 6: After that you put the rope in the water

Findings

Describe your crystals in the table below.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	The borax is like a tiny sugars	Tiny	Hard
Sugar	No crystal formed
Salt	Snow	Snow flake	Brhle

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
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

Explain how the following crystals are formed?

Type
Salt	Sea water, Pond, Sun, Evaporated, Salt
Sugar	Sugar, Chops ot up. Squish, Roll, Juice, Heat, Evaporated, Sugar Crystals
Snowflakes	Dust, Water freezes to the dust, More water frezzes to it
