Goal 3

The learner will conduct investigations and utilize appropriate technologies and information systems to build an understanding of the hydrosphere.

Objective 3.01

Analyze the unique properties of water including:

  • Universal solvent.
  • Cohesion and adhesion.
  • Polarity.
  • Density and buoyancy.
  • Specific heat.

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.

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.

Grand designs and great failures
Students develop an explanation of why two real-life ships, the British Titanic and the Swedish Vasa, sank. This application of knowledge to real-life situations demonstrates to students that even good designs can fail and that the... (Learn more)
