| How in the world do lichens (say: "like'-ens") survive on the hot, dry surfaces of rocks? Do they get most of their water from the air? Lichens are symbiotic "extremophiles." Consisting of two organisms helping each other, they thrive in extreme environments. We will do experiments that will hopefully tell us how they get water.
||What you will need:Some lichen scraped from a rock|
but not from a treeA sensitive weighing scaleA humidity chamber (large bottle)
Your experiments will have important implications leading to knowing how...humans can learn to live on Mars
we can preserve body tissues for surgical organ transplants
