The Butterfly Project

In the butterfly project we were givin blank sheets of paper with butterfly outlines on them. Our task was to color them in to make them camouflage with something in the room. Then we had to hind them where they would camouflage. After that another teacher would come into the room and look for them. In the first round the lights were on. In the second round the lights were off. In the third round we put them where they wouldn't camouflage well. Then the fourth round was the same as the first. This was a very fun project and by far my most favorite. It really showed me how important camouflaging can be. Whether you are in war or hiding yourself from a pedator this is an extremly important quality to have.

Symbiosis: Good, Bad or Both

What is Symbiosis? Symbiosis is the relationship between two living organisms. There are three different types of Symbiosis. They are Parasitism, Mutualism, and Commensalism. Parasitism is the relationship where one benifits and the other is harmed or hurt. Mutualism is the relantioship in which both the creatures benifit. Commensalism is the relationship where one creature benifits and the other is not harmed. Did you know that nematodes are able to kill harmful parasites with parts of their insides that we didn't know that they had.http//www.Sciencedaily.com/releases/2008/09/080921162235.htm. Did you also know that you have mites on your body that are in commensalism with you. They eat your skin so they benifit and we don't get harmed from them. I personaly think that Symbiosis is like meeting a friend at the park. I'm saying this only because I learned that Symbiosis is a relationship between two living organisms.
