This Year in Science

TWIS #14

      This week in science I got in a group and I did some research about oil. Then me and my group made a poster about it, then we did a presentation about it. The presentation could have been a little better if we had we had a little more time to put some information on the poster. I also read an article about H.I.P.P.O. I'm not talking about the animal hippo. I'm talking about Habitat loss Introduced species Pollution Population growth and Over-consumption. I mostly payed attention to Population growth because that was the most interesting to me. That's what I did this week in science.

      This week in science I learned about oil. I learned that we make deodorant, crayons, ink and a lot of stuff we have today. Those things are all made with oil. I also learned that more than half of the U.S produces oil. The article said that thirty one states produce oil. I also learned that using oil causes air pollution. I also learned that oil is a nonrenewable substance. That means that it can not be replaced with any other substance. Something different that I learned that the Earth's population is too big. I seen a video and they said about every fifteen to twenty years a million more people gets added on to the Earth's population. I also learned that one out of those three people don't have a good water system or any other resources that humans need to survive. Maybe since that's the case hopefully the Earth's population will drop little by little.That's what I learned this week in science.

           I think if we were to take out all of the plants and seal the tank then the spider would die because the plants breathe out oxygen and the spider need oxygen to survive. I think if we were to add five more spiders then we would have to add more plants so there would be more oxygen around in the tank that their breathing in. I think if there was never fruit flies then the spider would die of starvation. And plus the spider wouldn't have no energy because the spider needs its food to get energy.

               This week in science i didn't really do much. This week I made a little booklet for my spider observation project. I made spider man as the cover page of it. I put like the biotic and abiotic things of my spider tank in it. I put the definitions of the different symbiotic relationships and I also put examples of it. I also put in some information of the cellar spider like what does it eat, what environment it lives in, what predators does the cellar spider have you know simple questions like that. I also fed my spider a little bit of food. You can tell that he was hungry because it started going crazy all around the tank when we started putting the fruit flies in. I'm sure he was going crazy because of starvation. I also had to do a couple of packets with things that have to do with consumers, producers, food pyramids stuff like that. Thats what I did this week in science.
              This week in science I learned what was mutualism, commensalism, and parasitism. Mutualism is when both organisms get a benefit to something. So like its good for both organisms. Commensalism is when it benefits one animal but it don't really do anything to the other animal. Parasitism is when one animal gets a benefit to but it would be bad for the other animal. I also learned that the cellar spider eats fruit flies. I knew they eat some type of insect. I also learned that the cellar spider starts to create their web fast. I haven't seen a spider create their web any faster then the cellar spider. But then again I didn't really see any other spider create their web. One thing about the cellar spider is that I want to be able to see the web. The web is very thin and clear. That's what I learned this week in science.
