Corals have adapted in several ways to life on the deep reef. One of the ways that they have adapted is color. Corals on the deep reef tend to be darker.
This experiment is designed to test the hypothesis that deep reef corals are darker, because they need to absorb more of the available light. To test this, select different coloured materials and place thermometers under them. Shine a light on the different materials or leave in the sun to see how much energy is absorbed by the different colours.
