This Year in Science - 10th Grade Intro Video

TWIS#11

         







         This week in science we were told that we was going to have a cellar spider and we had to make a stable environment in the tanks that was giving to us. In class a to watch a video on how cellar spiders capture its prey.But before that happen their were papers all around the classroom that had to do with the ecosystem such as plant cells, chloroplast, carbon cycle, producers, decompose rs,and many more.We were given post its and had to write a definition as to what we know about that word. After that we got our tank and a white piece of paper and was told to sketch a picture as to what we want the ecosystem to look like for our spider. After days passed we went to Seward park to collect abiotic and biotic thing for the tank. My group got dead plants, sticks, little insects, a center pied, and other biotic and abiotic things. Abiotic is a nonliving thing and boitic is living things.

    I have learned many facts about cellar spiders and how the ecosystem works. I learned that cellar spider are often compared to daddy long legs because of their thin long legs. I also learned that cellar spiders like very dark places they are commonly found in the United States in houses or basements. I know that cellar spiders could only live up to a year and when it is ready to capture its prey, the spiders legs move in a 360 motion very rapidly that you cannot see the wrapping of the web.

This is my spider log book that I
created to keep information on my spider. 

              This week in science was a very interesting week because we had to learn about symbiotic relationships,energy pyramids, and food chains. A food chain shows each how each living thing gets its food. A energy pyramid is different levels that represents groups of organisms.A symbiotic relationship is mainly from the root symbiosis which is an interaction process between two or more biological species. However it is split up into different categories which is mutualism, parasitism and commensalism. Mutalism is the relationship between two species of organisms in which both benefit from the associate. Commensalism is the living together of two organisms in a relationship that is beneficial to one and had no effect on the other. Parasitism is a symbiotic relationshipin which organism benefits and the other doesn't. We also watched brain pop videos about them and test our knowledge by doing worksheets. 

            This week in science I did a lot of things such as creating ,my spider log book and  writing down what I found interesting in the tank and what had change through out the ecosystem, the days I  wasn't able to check it.  We also played a game on David's blog about symbiotic relationship and how one organism could affect the  food chain and how  the ecosystem works.

TWIS #13

Objective: If we were to add five more spiders to your spider habitat tank, what would happen? And why? Use these terms in your explanation: glucose, photosynthesis, energy, carbon dioxide, oxygen.




                    If you were to add five more spiders the habitat that we have provided for our spider(London) then the spider might live. I state this as my hypothesis  because in a ecosystem thier is a cycle. This cycle goes like this; the sun gives light to the damp soil that is filled with H2O which make producers (plants). They are autotroph in other words makes their own food. From there the producers goes into the next stage that produces glucose which is sugar. The glucose helps the seedling grow because it gives the seedling the extra carbon that is need. After that, the consumer which is meat eaters and also considered a heterotoph because it cannot make its own food and have to depend on other organisms to live. However it helps the cycle because it gives the autotrophs Co2(carbon dioxide) and the autotroph helps them by producing O2(oxgen) back. This is the cycle of photoosynthesis, which is green plants, algae and some bacteria use light energy from the sun to convert carbon dioxide and water into chemical energy in the form of glucose (sugar). In the process, oxygen is released into the atmosphere. Therefore the spider will live because of the elements hat is in the cycle. Therefore without one element it could throw the whole cycle of because they all depend on each others for the supply that is needed.
