PurposePurpose

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

ProblemProblem

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

HypothesisHypothesis

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

Key TermsKey Terms

• The key terms for this lab are sink, swim, The key terms for this lab are sink, swim, and molecules.and molecules.

• Sink- to descend to the bottom or Sink- to descend to the bottom or submergesubmerge

• Swim- to move through water by means of Swim- to move through water by means of the limbs, fins, or tail the limbs, fins, or tail

• Molecules- a group of like or different Molecules- a group of like or different atoms held together by chemical forces atoms held together by chemical forces

ProcedureProcedure

• 1. Fill glass 3/4 full with vegetable oil1. Fill glass 3/4 full with vegetable oil

2. Place an ice cube in glass and watch 2. Place an ice cube in glass and watch what it does - Does it sink or swim?what it does - Does it sink or swim?

3. As the water melts, watch what 3. As the water melts, watch what happens - Does is sink or swim?happens - Does is sink or swim?

ObservationObservation

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

ConclusionConclusion

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