Float and Sink
We're not talking about the kitchen sink. Learners explore what types of objects sink and float in water in an inquiry-based activity. With experimentation, they find similarities between materials that float and those that sink.

Comparing the Density of an Object to the Density of Water
Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...
Curated OER
Sink or Float
Using a variety of objects, learners conduct buoyancy experiments. They make predictions on which object will sink or float and test their predictions. They use a graphic organizer to record their findings.
