Hurumanu-Crystal

Aim: To learn about a saturated solution and how to make crystals

Crystal video

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

Borax Crystals time lapse video

Ratio; 3 Tablespoons Borax per 1/2 cup water

Materials

1)Borax

2)Cups

3)Hot water

4)Stick

5)String

Process

Step 1:Add Hot water

Step 2:Add Borax

Step 3:Mix with Stick for ten minutes

Step 4:Make a star with some wire like shown above

Step 5:Use a peg and clip it to the star

Step 6:Put the star in the water and make sure the pegs not in water with it

Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1)Sugar

2)Cups

3)Hot water

4)Stick

5)String

Process

Step 1:Add Hot water

Step 2:Add Sugar

Step 3:Mix with stick for ten minutes

Step 4:Get a string and tie it to a ice cream stick

Step 5:Put the string inside the water and the stick at the each end of cups

Step 6: 

Salt Crystals

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1)Salt

2)Cups

3)Hot water

4)Stick

5)String

Process

Step 1:Add hot water

Step 2:Add salt

Step 3:Mix with the stick for ten minutes

Step 4:Get a string and tie it to the ice cream stick

Step 5:Put the string inside the water and the end of stick touch both side of cup

Step 6:

Findings

Describe your crystals in the table below.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	One big crystal	Large, Medium, Small.	Hard
Sugar	Cube	Small	Hard
Salt	Cube	Small	Hard

How is salt formed
How is sugar formed
How are snowflakes made 

Explain how the following crystals are formed:

Type	Explanation
Salt	As the water evaporates, the smallest particle begins to bond together. First, it is a single molecule and then slowly the molecules will bond together forming a crystal. Every single molecule will form into the same shape, the salt crystal will form into a six-sided dice. But it mostly is chunky.
Sugar	As the water evaporates, the fluid becomes more holdable of the water and the sugar molecules will continuously come out of the fluid and becomes hard slowly.
Snowflakes	It begins to form when the cold drop of water freezes onto a pollen or a dust particle in the sky, this then creates an ice crystal. As the ice crystal falls down, the smoke and other kinds vapour freezes onto the ice crystal building it into a shape like the one on the left. There's the snowflake.
