In this exercise, your students' powers of observation are challenged and an introduction to the interactions of chlorophyll and light are examined. Additionally your students will be faced with having to alter their conceptual point of view based upon their changed physical vantage point. Biological Concept Science is the systematic questioning of what is not known. It is also the continuous questioning of the currently held dogma.
Students frequently can learn the facts of science.
Here is an opportunity to ask them to reevaluate their thinking and to form testable hypotheses. Chlorophyll reflects wavelengths of the electromagnetic spectrum that we see as green. Chlorophyll absorbs light energy in the areas of the electromagnetic spectrum that we sense as red and blue. Energy from light is absorbed by electrons in chlorophyll. Eventually that energy becomes available to organisms as chemical bond energy.
