The case of the disappearing pitcher plants
This lesson addresses the cause and effect relationship between human interaction and a North Carolina endangered plant species. A role-playing scenario allows students to view the situation from a variety of positions and to collectively arrive at a solution to the problem.

Does it float? Exploring density
Density is a property of matter that requires abstract understanding from your students. This lesson plan is a hands-on lab for exploring the concepts of mass, volume, density, and their relationship. This lab achieves several 8th grade science objectives and incorporates mathematical objectives as well. The lab can easily be used as an introductory lab for the year, thus covering not only the content objectives, but also procedures for completing labs throughout the course of the year.

Exploring properties of matter with submersibles
This inquiry-based learning activity allows students to explore the relationships between mass, volume, density, and buoyancy as they manipulate various materials to construct a submersible “vehicle” for deep-sea research.

Submarines: Using mass, volume and density to create a working submarine
The students will design a submarine that will float, subsurface, sink, and return once again to the water's surface by external manipulation of the submarine outside of an aquarium. In order to accomplish this, the students will use not only the concepts of mass, volume, and density but will also integrate buoyancy and ballast in their submarine design.
