A Matter of Density

Given the depth, temperature, and salinity of ocean water, physical science classes use an online seawater density calculator to determine the density and sigma values. With the data, they assess the relationship between density and other factors. Then, they consider what happens to buoyant larva in these areas. This is a useful lesson to help middle schoolers make the connection between physical environment and species survival.
