Science Project: Solubility

We learned about what Solubility means in Science. Then we did a really neat experiment. 
These supplies are needed:
               4 plastic glasses (1 for each test material)
 1 teaspoon of salt
 1 teaspoon of sugar
 1 teaspoon of sand
 1 teaspoon of salad or cooking oil
 a plastic spoon or wooden stick for stirring

Follow these directions and answer these questions.

1. Fill each of the four glasses half-full of water.

2. Number each of the glasses 1 - 4.

3. In glass number 1 add 1 teaspoon of salt and stir.

Did the salt disappear?
Yes, after mixing it was completely gone

Is salt soluble in water?

4. In glass number 2 add 1 teaspoon of sugar and stir.

Did the sugar disappear?
Yes, after mixing it was gone

Is sugar soluble in water?

5. In glass number 3 add 1 teaspoon of sand and stir.

Did the sand disappear?
No, it mixed with the water, but was still there

Is sand soluble in water?

6. In glass number 4 add 1 teaspoon of oil and stir.

Did the oil disappear?
No, it floated on top of the water

 Is oil soluble in water?
