Middle School Chemistry: What Is 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.

Serc: Plastic Polymers: Investigating Their Flexibility
Students will use their prior knowledge about changes of matter to develop a hypothesis to test the physical properties of materials such as plastic (polymers) and how its chemical properties allow it to have unique physical properties.
