Crystals


 Chemistry - Crazy Crystals
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)A cup or Glass
2) Pipe cleaner
3)Borax
4)Popsicle Stick
5)string
6) Warm water
7) Spoon

Process

Step 1: We got A cup or glass
Step 2:Put 2 Teaspoons Of borax and 1/2 a cup of Warm Water
Step 3:Add ingredients to the cup Mix it all together with the Popsicle stick 
Step 4:Tie Your string to Your Popsicle stick

After watching the videos as a class, explain how the following crystals are formed:


Type
Explanation
Salt
How to Make Salt They Get Sea Water And Put that Sea water Into Ponds And then Sun Goes on to the ponds It then Evaporate And The water goes away and then they collect The Salt. 


Sugar
Sugar Cane,Cut it up,roll it/Squish,Get The juice,Heat it,Syrup,crystallisation


Snowflakes
