In this activity, students will see that a carrot slice sinks in fresh water and floats in saltwater. Considering the placement of the carrot slice in water and salt water, students will infer that the density of salt water must be...

In this activity, students will investigate whether the temperature of water affects its density. Students will place colored hot and cold water in a cup of room-temperature water to see that cold water sinks while hot water floats. Then...

This activity explores the property of density in a variety of liquids and solids.

In this science activity, you will stack several liquids, one by one, and create a colorful density column.

An activity to help you create a density column that contains layers of liquids that are separated by different densities.

Students explore the densities and viscosities of fluids as they create a colorful 'rainbow' using household liquids. While letting the fluids in the rainbow settle, students conduct 'The Great Viscosity Race,' another short experiment...

Students use the water-displacement method to find the volume of different rods that all have the same mass.

Deepen the students' understanding of density by constructing a simple hydrometer that can be used to compare the densities of different solutions.

How does oil seep naturally from beneath layers of rock to the surface of the ocean?
