Crazy Crystals

Home Chemistry - 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) A cups 

3)popsical stick

4)pape cleaner

5) hot water

6) string
7)spoon

Process

Step 1:Borax

Step 2:Add 4 spoons of Borax

Step 3:Place hot water into the cup

Step 4:stir till the borax has dissappered 

Step 5:tie a string to a popsical stick then tie a pipe cleaners into a star and attach it to the string

Step 6:place in the cup and let it sit for a few days

Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1)Sugar

2)A cups 

3)popsical stick

4)hot water

5) string

6)spoon

Process

Step 1:Sugar

Step 2:Add 4 spoons of Sugar

Step 3:Place hot water into the cup

Step 4:stir till the sugar has dissappered 

Step 5:tie a string to a popsical stick 

Step 6:place in the cup and let it sit for a few days

Salt Crystals

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1)Salt

2)A cups 

3)popsical stick

4)hot water

5)string

6)spoon

Process

Step 1:Salt

Step 2:Add 4 spoons of Salt

Step 3:Place hot water into the cup

Step 4:stir till the salt has dissappered 

Step 5:tie a string to a popsical stick 

Step 6:place in the cup and let it sit for a few days

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 flakes	small	Hard
Sugar	crastals	not	formed
Salt	starght	madium	Hard

What crystals worked out best and why?:

Conclusion:The Borax one worked the best becaues it was a snow flake and it was small and hard like crystal should be and what a crystal should look like it was very pretty and sparkly and rock like.

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:	7
Monoclinic Definition:	10
Orthorhombic Definition:	6
Trigonal Definition:	8
Hexagonal Definition:	8
Cubic Definition:	6
Tetragonal Definition:	12

Explain how the following crystals are formed?

Type	Explanation
Salt	sea water pond sun Evaporats water salt
Sugar	Sugar cane hup it up squish/roll juice evaporats water suger crystals
Snowflakes	Dust, water freezes to dust more water freezes to it
