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) Cup
3) Spoon
4) Water
5) Pipe Cleaners
6) Popsicle Stick
7) String
6) Popsicle Stick
7) String
Process
Step 1: Grab a cup
Step 2: Put 3 tablespoons of borax into a cup and 1/2 cups of water
Step 3: add them together
Step 4: mix until all mixed in
Step 5: fold pipe cleaners into a snowflake
Step 6:put snowflake on to the Popsicle stick
Sugar Crystals
Materials
1) Sugar
2) Cup
3) Spoon
4) Warm water
5) Popsicle
6) String
6) String
Process
Step 1: Add Some sugar
Step 2: Add 1/2 a cup of water
Step 3: Mix together with a Popsicle
Step 4: Tie String to the Popsicle
Step 5: Put Popsicle in the water
Step 6: wait
Salt Crystals
Ratio: 4 Tablespoons salt to 1/2 cup water
Materials
1) Salt
2) Cup
3) Spoon
4) Popsicle Stick
5) water
Process
Step 1: Add 4 Tablespoons of salt to the cup
Step 2: add 1/2 a cup of of warm water
Step 3: mix with a Popsicle stick
Step 4: Tie the string to the middle of the Popsicle Stick
Step 5: Put the stick in the water
Step 6: wait

Explain how the following crystals are formed?
Type
| |
Salt
| When people make salt they get it from the sea and then it goes into little ponds then the sun evaporates it then it turns into salt |
Sugar
| They Cut down The sugar cane and then they squish it until flat they separate the juice from the fibre then they heat it and get syrup then they use sugar to make sugar. |
Snowflakes
| The Snowflakes Fall down from the sky as dust and the the water molecules join the dust to sort of turn into a snowflake but then a little bit more happens |
Hello Tamani
ReplyDeleteWell done on this crystals blog. I have given you 1/2 possible points. In order to earn full points please complete the conclusion about your borax/sugar/salt crystals.
