#### The Great Ocean Conveyor

For Teachers 6th - 10th
Students investigate water density. In this water density lesson, students conduct an experiment with food coloring, water and salt to see how the salt effects bodies of water.

#### What's The Matter: A Sinker or Floater?

For Teachers 3rd - 5th
Students conduct an experiment. In this water instructional activity, students watch the instructional activity "Float and Sink" on an interactive website. Students learn how to test items in water and then work in groups to test their...

#### Oceanography: Density: Designing a Hydrometer Lab

For Teachers 6th - 8th
Middle schoolers explore water density and design a hydrometer to measure density. This activity is part of Ocean World's home site and excellent resources and links are provided.

#### The Weight of Water

For Teachers K - 3rd
Students examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.

#### Teacher's Guide For: Water Temperature and Salinity Experiment

For Teachers 4th - 5th
Students experiment with water density, temperature and salinity. In this water lesson plan, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.

#### Water Density Boundaries

For Teachers 5th - 8th
Students create observable layers in water that represent a separation based upon density differences. They model density boundaries using differences in temperature and salinity. They, in groups, perform a meaningful experiment...

#### Water Density and Stability Lab

For Teachers 6th - 12th
Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.
