Once again this year our friends from Biology joined us in our Saturday Morning at the Lab celebration of science. Watch as they demonstrate how Chlamydomonous (an algae) moves from the darkness into the lighted area of a petri dish. You can even add household chemicals to the mix to see how this affects the algaes response.
