Home Chemistry - Crazy Crystals
Aim: To learn about a saturated solution and how to make crystals
Definition of the 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
Materials
1) Tsp of Borax
2) Half of cup Boiling water
3) Pipe cleaner
4) Pegs
5) Spoon
6) Container
Process
Step 1: Put 1/3 of borax in the container
Step 2: Put hot water in the container but don't put too much.
Step 3: Get a spoon
Step 4: Make a star shape out of the pipe cleaner
Step 5: Put the star at the top of the hot water.
Step 6: Mixed it with the spoon
Step 7: Put it in a safe place where no one can touch it.
Step 7: Put it in a safe place where no one can touch it.
Sugar Crystals
Materials
1) Tsp of Sugar
2) Half of cup Hot water
3) Container
4) Spoon
5) Pegs
6) pipe cleaner
Process
Step 1: Put the sugar in the container
Step 2: Put 1/3 of hot water
Step 3: Mix it
Step 4: Grab 1 pipe cleaner and put it on the pegs
Step 5: Put the pegs with the pipe cleaner in the top of the container
Step 6: Mix it
Step 7: Put it on to a safe place
Step 7: Put it on to a safe place
Salt Crystals
Materials
1) Tsp Salt
2) Half of cup Hot water
3) Container
4) Pipe cleaner
5) Pegs
6) Spoon
Process
Step 1: put 1/3 of hot water.
Step 2: Put 1 tablespoon of salt.
Step 3: Grab 1 pipe cleaner and put it on the pegs.
Step 4: Put the pegs in the top of the container.
Step 5: Mixed it accordingly.
Step 6: Time to put it in the cart.
Findings
Describe your crystals in the table below.
Crystal Type
|
Shape
(Describe the shape) |
Size
(of individual crystals) |
Hardness
(Crumbly to Rock Hard) |
Borax
| Cubic | 1 to 2mm in diameter | hard |
Sugar
| None but mostly cubic | No crystal | No crystal |
Salt
| None but mostly cubic | 05 to 1 mm in diameter | Crumbly |
What crystals worked out best and why?: The Borax was the best crystal because it was mixed the best, the sugar should be better but sadly we did not mix it properly.
