This tutorial is an explanation of the properties of density.

Calculate the density of cubes made of different materials to determine what type of material it contains. Using this information explain that the size, mass, and arrangement of the atoms or molecules of a substance determines its density.

A lab experiment that shows students that different molecules melt in different ways. This lab also allows students to practice calculating and finding density, mass, and volume. Lesson plan includes lab handout for students.

Students use a tension-compression machine or an alternative bone-breaking setup to see how different bones fracture differently and with different amounts of force, depending on their body locations. Teams determine bone mass and...
