Butterfly Lab Response

In Yellow science class last week, all the students made butterflies and colored them so that they would camouflage into the classroom. We timed a predator(teacher) to come in and try to find them wherever they were hidden. Most of the butterflies were found in time, but some like mine was never found. There were four rounds, the first two were in normal classroom light, the 3rd one was in the dark, and the last one we had to hide the butterflies out in the open! It was entertaining to see the "predator" running around trying to find the last of the butterflies; especially when I hide mine on the back of the door that the predator came through!

Symbiotic Relationships Response

In yellow science class, I learned about symbiotic relationships and how they are important. There are three types of the symbiotic realtionships. The first one is mutualism, a mutualism relationship is where both the organisms benefit from the realtionship. For example, a human and pet dog both benefit because the dog has proper shelter, food, and the right enviornment; and the human gets a trustworty companion out of it. The next type of relationship is commensalism, this relationship is where only one organism benefits, and the other one is unharmed, basically a neutral. An example is a hawk which rests on a branch, the branch is unharmed, and the hawk gets a break. The last relationship is parasitism, this is where one benefits, and the other organism is harmed, bothered, or affected health wise. Fleas on a dog would be a perfect example because the fleas benefit from having somewhere to live; but unfortunatley, if the dog itches too much, it could get an infection through all those scratches. Though there are ups and downs to these relationships, it is important to the everyone and everything because these realtionships are how some organisms live, some remain the same, and some don't.
