Investigating the Effect of Salinity on the Density and Stability of Water
Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

How Much Ocean?
In this ocean learning exercise, students are given a map of the world and they predict the amount of water that covers the Earth's surface. They count the total number of squares on the given map that represent the water and they land...

Fresh Water From the Oceans?
Students participate in an activity in which they demonstrate how the evaporations of water from the oceans results in fresh water in the form of rain. They create a saltwater solution in a flask and boil the water until most of the...
