2. Purpose
The purpose of this lab is to explain the effect of the ice cube in a glass of vegetable oil. Also, to determine whether it sinks or swims.

3. Problem
If you put an ice cube in a glass of vegetable oil, will the effect of it come to it to be sinking or swimming?

4. Hypothesis
I think that if you put an ice cube in ¾ filled glass of vegetable, the ice cube will sink to the bottom of the glass.

5. Materials
1.Tall glass or jar 2.Vegetable oil or other cooking oils will do 3.Ice Cube

6. Key Terms The key terms for this lab are sink, swim, and molecules.
Sink- to descend to the bottom or submerge
Swim- to move through water by means of the limbs, fins, or tail
Molecules- a group of like or different atoms held together by chemical forces

7. Procedure
1. Fill glass 3/4 full with vegetable oil 2. Place an ice cube in glass and watch what it does - Does it sink or swim? 3. As the water melts, watch what happens - Does is sink or swim?

8. Observation
While doing this experiment, I observed that when the water was frozen, molecules expanded and took up more room than when they were liquid.  Because both the ice cube and water weigh the same, the ice cube is less dense when it floated in oil.

9. Conclusion
I was wrong. When I put the ice cube in the glass of oil, it swam in the glass. It didn’t sink. My hypothesis turned out to be incorrect.
