Density - To Float or Not to Float? That is the Question!
Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.
Curated OER
Ice Cream
Students are shown an experiment making ice cream while discovering the freezing point depression. There are questions for students to answer after the demostration.

Effects of the Southern Pacific Railroad Causeway
Fifth graders describe the appearance of a substance before and after a physical change. They re-create the Southern Pacific Railroad Causeway across the Great Salt Lake. They determine for themselves how the water is exchanged...

What Changes Occur When Ice Melts?
Young scholars explore the physical process of melting. They observe melting ice and answer questions related to energy transfer during phase changes.
Curated OER
Household Waste (Down the Drain)
Students brainstorm in small groups about the various ways water comes into their house. They list ways wastewater is produced in and around the home. They do an at-home inventory of all water drains and report their findings to the class.

Physical and Chemical Changes
Eighth graders distinguish between physical and chemical change. In this chemistry lesson, 8th graders observe a series of demonstrations showing physical and chemical changes. They identify the signs that a chemical reaction took place.

Designing a Flotation Strategy for the Purification of Recycling
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...
