Density Column Lab - Part 1
Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects.
Curated OER
Density Of A Material
Students determine the density of a material created in the laboratory and observe physical and chemical changes. They engage in a lab activity, and answer questions on a worksheet imbedded in this plan.

Density Column Lab - Part 2
Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the liquids...
Curated OER
Laboratory - Density of a Material
Middle schoolers conduct a lab (with water, guar gum and sodium borate) and carefully record physical and chemical properties and changes throughout the session, and experiment with weighing by difference.
