Using a Spreadsheet to Understand Density
Learners use density to identify what metal a gold colored weight is made of. They use a spreadsheet to graph the experimental density of common metals and compare the know densities to their calculated density of the known metal.
Curated OER
Density Derby
Students explore the relationship between mass, volume and density. They use model boats to discover how changing mass and volume affect density. This is a very engaging lesson which provides great demonstrations and hands-on activities.

Density and Convection Currents
Students listen as the teacher explains convection currents in the ocean. They experiment with finding a smoking match in the classroom with their eyes closed. Students discuss what might effect their ability to pinpoint the smoke...
Curated OER
Density
Students explore and analyze the relationship between density, mass, volume and ratios. They complete a lab to define mass and volume and then show the density that equals a mass and volume formula. Their lab involves a suitcase,...

To Float or Not to Float - Density
Students experiment floating a variety of objects in various liquids. They discover how density affects the ability of an object to float and apply the concept of density to solve problems.
Perkins School for the Blind
Volume, Mass, and Density Boxes
Mass and density are difficult topics for kids to understand, and even more difficult when you have visual impairments or blindness. Learners will make boxes and fill them with cotton, sand, or crushed paper. They will feel the density...
