Museum of Science: Water Density Experiment
A simple lab activity to demonstrate that ocean currents are influenced by changes in water density.
Science Fun for Everyone
Science Fun: Water Fireworks
In this science experiment, you will learn about density while making water fireworks!

Lapeer County Schools Science Resources: Density Lab
A simple lab experiment for students to find the density of two solids and a liquid (does not use water displacement). Note that number 1d should not state "weighs" since mass is being found.

Pbs, Secrets of the Ocean Realm: Mountain in the Sea
This experiment allows your students to study the effect of temperature on water motion and also to create their own density driven current.

Science Buddies: Buoyancy of Floating Cylinders
This project presents an interesting puzzle. A disk of wood will float face-up, that is, with its circular cross-section parallel to the surface of the water. A long log of wood, however, floats with the circular cross-section...
University of Chicago
Center for Astrophysical Research in Antarctica: Don't Be Too Flaky
After reading some facts about the properties of water, students conduct experiments to measure the relative densities of water, ice and snow and submit the results to the website.

Bigelow Laboratory for Ocean Sciences: Salinity and Deep Ocean Currents
For this activity, students will investigate how temperature and currents affect the salinity of ocean water, making predictions after studying ocean maps. It is recommended that teachers do the experiment themselves before presenting it...
