Twelfth graders work in teams to design a method of recycled plastics purification by flotation. They base their design on the concept that different kinds of plastics have different densities and keep overall costs and purification time...

Young scholars watch a video clip about German submarines lost during World War II. They work together to create their own submarine out of a plastic bottle. They test the buoyancy of the submarine in different activities.

Students use water, beakers, hot plates, paper dots, and goggles to participate in a hands on activity where they see how a convection current creates wind. In this convection current lesson plan, students participate in a hands on...

Students identify the characteristics and composition of emulsions. In this chemistry instructional activity, students classify household products according to emulsion type. They explain how to make the best emulsion.

Students explore the field of nanotechnology by examining magnetic field strength in ferrofluids. They use probes attached to a computer program to determine the relationship between magnetic field strength and magnetic field lines.

Third graders act as scientists. In this property discovery lesson, 3rd graders explore the substance "Oobleck" (cornstarch, water, food coloring). They work in groups to investigate the substance and make observations as a scientist...

Young scholars use a microscope and observation skills to compare and contrast several physical properties and develop a classification system.

After students conduct the two associated activities, Density Column Lab - Parts 1 and 2, present this lesson to provide them with an understanding of why the density column's oil, water and syrup layers do not mix and how the concepts...

For this inquiry lab activity, students will attempt to layer 6 different kinds of soda pops in a large test tube using their knowledge of density and other physical properties of liquids.

Because different liquids have different properties, density also differs. In this activity from the Illinois Institute of Technology, students will calculate densities of water, dish-washing detergent, cooking oil, and other liquids.

This lab experiment has students observe and compare the density of five different liquids while measuring mass and volume.
