Sweetness and Light
Students work in teams to discover which colors (wavelengths) of visible light penetrate furthest into local waters. A diver working at a depth of 33 feet (10 meters) cuts his on a sharp rock. As he looks down at his leg he sees blood flowing from the wound. What color is the blood he sees?
The Incredible Shrinking Cup Lab
Learn how students can develop hypotheses to test the effects of depth and pressure on the volume of Styrofoam cups by deploying the cups off the US EPA’s R/V Lake Guardian in Lake Superior. A great lesson showing the integration of Boyle’s Law and ocean physics.
