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)Borax
2)Water
3)peg
4)cup
5)pipe cleaners
Process
Step 1: add water to a cup
Step 2: add borax
Step 3: mix the borax and water
Step 4: Get pipe cleaners
Step 5: Make pipe ckeaners into a star
Step 6: put the peg on the star and put it in the liquid
Sugar Crystals
Materials
1)Sugar
2) Water
3) String
4) stick
5) cup
Process
Step 1: Add water to a cup
Step 2: Add the sugar to water
Step 3: Mix
Step 4: Add string to stick
Step 5: put string into liquid
Ratio: 4 Tablespoons salt to 1/2 cup water
Materials
1) Salt
2) Water
3)Cup
4)Stick
5)String
Process
Step 1: Add water in a cup
Step 2: Add salt
Step 3: Mix
Step 4: Add string on a stick
Step 5: Put the string in liquid
Findings
Describe your crystals in the table below.
Crystal Type
|
Shape
(Describe the shape) |
Size
(of individual crystals) |
Hardness
(Crumbly to Rock Hard) |
Borax
| Squares/triangles | Large | Hard |
Sugar
| Square/rectangle | Small | Hard |
Salt
| Cube | Medium | Hard |
Conclusion: I learnt that they are all different shapes and sizes, and they are all different I also learnt that they are really easy to make. But they didn't quite finish but when I researched that's what I found out.

How are snowflakes made
Explain how the following crystals are formed:

Explanation

Salt
|
While the ocean is full of a lot of salt. mining of salt involves pumping water below the earth's surface to dissolve the salt and create a salt brine. This brine is then pumped to the surface and evaporated to create salt. Most table salt is made this way.
|
Sugar
|
Suger is made by sugar canes, It's processed and gets rid of all the bad stuff. You can also get sugar from sugarbeet. The sugar syrup gets boiled and then cooled.
|
Snowflakes
|
It's when water drops down and the air is so cold it freezes and the hydrogen forms a different shape each time.
