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) Pipe cleaners.
2) String.
3) Pegs.
4) Borax.
5) Cups.
6) Sugar.
7) Salt.
8)Stirring stick.
Process
Step 1: Get a cup and label it.
Step 2: Add the sugar into the cup.
Step 3: Add the warm water and mix.
Step 4: Tie a string around the stick.
Step 5: Place the popsicle stick with the string and put it in the cup.
Step 6: Leave it alone for a week and then come back and see what changed.
Sugar Crystals
Materials
1) Sugar.
2) String.
3) Water.
4) Cup.
5) Mixing stick.
Process
Step 1: Get a cup and label it.
Step 2: Add the sugar into the cup.
Step 3: Add the warm water and mix.
Step 4: Tie a string around the stick.
Step 5: Place the popsicle stick with the string and put it in the cup.
Step 6: Leave it alone for a week and then come back and see what changed.
Ratio: 4 Tablespoons salt to 1/2 cup water
Materials
1) Salt.

Conclusion:
Today in science we did a experiment called crystals but I didn't do the experimetnt because I wasn't here on Thursday. This time in science I had different people in my group, Anneleise, Janel, Khaylanie and Baliey.
We had to get three cups and add borax, Sugar and salt in each one, then add the warm water and mix with a Popsicle stick. After that we tied a string onto the stick and placed it into the cups with Sugar and salt. Then we had to leave it at school for two weeks and see whats changed when we come back.

After watching the videos as a class, explain how the following crystals are formed:
Type
|
Explanation
|
Salt
|
Salt is formed by the evaporation of satly water (such as sea water).
|
Sugar
|
Sugar is made from raw sugar and is from sugarcane or sugar beet.
|
Snowflakes
|
A snowflakes is fromed what is droplet of cold water freezes.
