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.
Ratio; 3 Tablespoons Borax per 1/2 cup water
Materials
1) Pipe Cleaners
2) Peg
3) Borax
4) Stirring Stick
5) Warm Water
Process
Step 1:Shape pipe cleaners into stars
Step 2: Hang star o
Step 3: Label your cup
Step 4: Make up salt solution
Step 5: Tie some string onto your stirring stick
Step 6: Make sure the string is in the Saturated solution
Sugar Crystals
Materials
1) String
2) Sugar
3) Cup
4) Stirring Stick
5) Warm Water
Process
Step 1: Make your Saturateded mixture
Step 2: Mix it for about 5-10 mins
Step 3: Tie a piece of string onto your stirring stick
Step 4: Place it into your mixture and
Step 5: Wait for maybe a week
Step 5: Wait for maybe a week
Ratio: 4 Tablespoons salt to 1/2 cup water

Findings
Describe your crystals in the table below.
Extra Findings while mixing...
I found that when mixing it takes a little while to make the mixture but also when you leave it for a few secounds, and you scrape your stick along the bottom and bring your stick up it still has borax on it but then disolves again.

Explanation
|
Salt
|
Salt is formed by an evaportation by salty water, like sea water. Enclosed bays are where you could find sea salt. In region places.
|
Sugar
|
Most green plants produce sugars, they create a form of sugar. If a plant makes more food than it requires, it stores it. The sugar is made from many green plants.
|
Snowflakes
|
A snowflake creates an ice crystal. Water Vapour freezes normal crystals, building new ones - A snowflake also has 6 arms, sometimes
