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
Image result for borax crystals
Ratio; 3 Tablespoons Borax per 1/2 cup water
Materials
1) cup
2)salt
3)sugar
4)borax
5)mixing tool
6)string
7) stick
Process
Step 1:get a cup.
Step 2: then the teacher puts hot water in to your cup.
Step 3:then the teacher comes to you and puts sugar,salt or borax in to your cup.
Step 4:then you mix the sugar,salt or borax.
Step 5:then you get a stick and string and you rap the string around the stick.
Step 6:then you leave the stick and string in the water to form the crystals.
Sugar Crystals
Grow your own Sugar Crystals
Ratio: 1 cup sugar to 1/2 cup water
Materials
1)sugar
2)a plastic cup
3)string
4)stick
5)hot water
Process
Step 1:get a cup.
Step 2: then the teacher puts hot water in to your cup.
Step 3:then the teacher comes to you and puts sugar in to your cup.
Step 4:then you mix the sugar.
Step 5:then you get a stick and string and you rap the string around the stick.
Step 6:then you leave the stick and string in the water to form the crystals.
