Curated OER
Thermo and Fluid Dynamics of a Homemade "Lava Lamp"
High schoolers construct their own lava lamp using simple substances. In this physics lesson, students explain how difference in density causes convection. They solve for forces and buoyancy using mathematical equations.

Boy, Is That Buoyant!
Fourth graders see that salt increases the density of water and creates a condition wherein objects are more buoyant than would be expected under normal conditions. They describe the relationship between heat energy, evaporation and...

Properties of Matter
Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...
