Observe each layer of liquids with different densities. Weigh liquids to verify observation. Discuss findings with classmates who are experimenting with different liquids. The teacher will need each of the various liquids, a chart to record class predictions, and a large beaker. Large enough to hold all liquids.
Procedure Discuss the term density using examples from the water vs. alcohol activity.
This activity will extend the concept of different densities. Show how to use of the liquid and how to measure each. Explain the steps of the activity. Predict which liquid will float on top of which. Draw this on the activity sheet.
