Science Experiment

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) spoon
3) String
4) pen
5) Borax


Process

Step 1: Get a cup.
Step 2: Put a borax in the cup
Step 3: Get a hot water.
Step 4: put some hot water in the borax
Step 5: Mix the borax.
Step 6: get some string tie it around into the Popsicle stick and in the pipe cleaner after that let the pipe cleaner to go down in the water.
Sugar Crystals

Grow your own Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water
Materials

1) Cup
2) spoon
3) string 
4) Popsicle stick
5) pen

Process

Step 1:Get a cup and a spoon.
Step 2: Put a sugar on a cup.
Step 3: Get a hot water.
Step 4: put a hot water in a cup.
Step 5: mix it together with your Popsicle stick. 
Step 6: get some Popsicle stick and a string and tie it around on the Popsicle stick and let the string go down in the hot water.



Salt Crystals

Ratio: 4 Tablespoons salt to 1/2 cup water
Materials

1) cup/spoon
2) Pipe cleaner
3) string 
4)Popsicle cleaner
5) salt

Process

Step 1. get a cup and spoon.
Step 2: Put a salt in the cup.
Step 3: get a warm water.
Step 4: mix it together with a Popsicle stick.
Step 5: get some string and tie it around in the Popsicle stick.
Step 6: get a pipe cleaner and tie the string into a pipe cleaner and put it in the water.

Explain how the following crystals are formed?



Type

Salt

sea water and sun Evaporates water
Sugar
sugar cane, they chop it and squish/roll and juice heat evaporate water.


Snowflakes
dust water freezes more water freezes to it
