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)
Borax Crystals
Ratio; 3 Tablespoons Borax per 1/2 cup water
Materials
1) Borax
2) Cup
3) Popsical stick
4) water
5) string
6) pipe cleaner
6) pipe cleaner
Process
Step 1: Borax
Step 2: add in 4 tea spoons
Step 3: place warm water into a cup and pour in the powder
Step 4: stir until powder is gone
Step 5: tie a string to a popsical stick then tie pipe cleaners into a star and attach it to the string
Step 6: place in the cup and let sit for a few days
Sugar Crystals
Materials
1) Sugar
2)Cup
3) Popsical stick
4) water
5) string
Process
Step 1: sugar
Step 2: add in 4 tea spoons
Step 3: place warm water into a cup and pour in the powder
Step 4: stir until powder is gone
Step 5: tie a string to a popsical stick
Step 6: place in the cup and let sit for a few days
Salt Crystals
Ratio: 4 Tablespoons salt to 1/2 cup water
