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) water

3) cups

4)stick/Popsicle stick.

Process

Step 1: grab the cup                                        

Step 2: fill cup with water

Step 3:put borax in it

Step 4: mix it around

Step 5: put a stick with a star on top

Step 6: sit and wait takes week

Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1)sugar

2)water

3)cups

4)sticks/Popsicle.

Process

Step 1: grab the cup

Step 2:fill cup with water

Step 3:put sugar in it

Step 4: mix it with stick

Step 5: put a stick with a star on top

Step 6: wait takes week it think

Salt Crystals

2) cup 

3)sticks/Popsicle.

4)water

Process

grab the cup

Step 2:fill cup with water

Step 3:put salt in it

Step 4: mix it with stick

Step 5: put a stick with a star on top

Step 6: wait takes week it think

Findings

Describe your crystals in the table below.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	circle	10cm	it is very hard
Sugar	square	2m	soft
Salt	square	10 m below	hard

What crystals worked out best and why?:

Conclusion:

________________________________________________________________________

Type	Explanation
Salt	salt is formed from the sea and sand when hitting shore. the sea gets salte from rain coming down and the fish live in salt water that helps them live.
Sugar	sugar is formed from sugar cane it goes through a machine the processes begins the sugar forms it self in to cubes that is what they call sugar cubes.
Snowflakes	snow flakes are formed when it is cold and snowy there are things that move fast more colder they move slower and forms a snowflake.

After watching the videos as a class, explain how the following crystals are formed:

Type	Explanation
Salt	salt is formed from the sea and sand when hitting shore.
Sugar	sugar is formed from sugar cane or sugar beet root.
Snowflakes	snow flakes are formed when it is cold and snowy
