The Rainbow Connection
Scenario: A scuba diver is collecting brownish-green algae for the Smithsonian. During her collection, she cuts her finger and is aghast to discover that her blood is brownish-green. Imagine her relief when she surfaces and realizes that her blood looks normally red, as is the algae she collected. We explore the origin of these color changes as a means of demonstrating the physical properties of light, light energy capture by organisms, and photosynthesis.

How do environmental or anatomical factors
effect the rate at which plants
remove water from the soil?
