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) water
2) borax
3) cup
4) popsicle sticks
5) pipe cleaner
6) peg
Process
Step 1: pore water into a cup.
Step 2: Add three tablespoons of borax
Step 3: mix the borax with the popsicle stick
Step 4: get pipe cleaner and fold into start shape.
Step 5: put peg onto the pipe cleaner and put pipe cleaner into the cup.
Step 6: Wait a few days until crystals are made.
Sugar Crystals
Materials
1) 6 tablespoons of sugar
2) water
3) cup
4) string
5)popsicle stick
Process
Step 1: pore water into a cup.
Step 2: Add six tablespoons of sugar
Step 3: mix the sugar with the popsicle stick
Step 4: tie string to the popsicle stick
Step 5: put a stick on top of the cup with the string inside the liquid.
Step 6: Wait a few days until crystals are made.
Ratio: 4 Tablespoons salt to 1/2 cup water
Materials
1) salt
2) water
3) popsicle stick
4) string
5) cup
Process
Step 1: put water into a cup
Step 2: add three tablespoons of salt.
Step 3: mix the liquid with a popsicle stick.
Step 4: tie string to the popsicle stick.
Step 5: put the string into the cup with the popsicle stick on top of the cup.
Step 6: wait until crystals appear.
Findings
Describe your crystals in the table below.
Crystal Type
|
Shape
(Describe the shape) |
Size
(of individual crystals) |
Hardness
(Crumbly to Rock Hard) |
Borax
| round with points | Large, medium and small | Hard |
Sugar
| Cube | Small | Hard |
Salt
| Cube | Medium | Hard |
What crystals worked out best and why?: Borax because of the shape it was and it was the biggest.
Conclusion:
The borax crystal was the best and the shape of it was my favorite. It was also Hard
The Sugar crystals were the smallest and it was also Hard when we felt it.
The Salt crystals were right in the middle of the size and it to was hard to touch.
We learnt alot about crystals and it was very cool to see how they turned out.
I wish I could do this again.
