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.

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

Grow your own Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

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

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.

What crystals worked out best and why?: 

Conclusion: 




Type
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
