Aim: To learn about a saturated solution and how to make crystals
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.
Ratio; 3 Tablespoons Borax per 1/2 cup water
Materials
1)Pipe cleaners
2)Pegs
3)Borax
4)Popsicle stick
5)warm water
6) Cup
Process
Step 1:Put warm water into cup
Step 2:
Step 3:
Step 4:
Step 5:
Step 6:
Sugar Crystals
Materials
1)Strings
2)Sugar
3)Cup
4)Popsicle stick
5)Warm water
Process
Step 1:Get some sugar and put it in the cup.
Step 2:Get some warm water and also put it in the cup.
Step 3:Mix it in together with the popsicle stick.
Step 4:Tie a string to the popsicle stick.
Step 5:Dip the string in sugar.
Step 6:Put it in the cup.
Ratio: 4 Tablespoons salt to 1/2 cup water
Materials
1)Salt
2)Popsicle stick
3)String
4)cup
5)warm water
Process

Explanation
|
Salt
|
It happens when the salt water goes up into the air and it evaporates. That is how it will form the salts together That is how it turns in to a crystal.
|
Sugar
|
The water will evaporate then the sugar will concentrate. And it will stick to the string until it adds to the other crystals. It evaporates the solution and saturates the sugar molecules.
|
Snowflakes
|
It starts when a super cold drop of water freezes onto a dust particle or pollen, It will start to form an ice crystal.But when water freezes the molecules of it will make a hexagonal pattern which makes the body of a snowflake. As the snowflake falls and touches other drops of water it will freeze onto the ice crystal and that's how it makes the 6 arms of the snow flakes.
