You may have been wondering why the sky is blue? You might be thinking that it may be a different color. What is the real scientific explanation for why the sky is blue. The sky is blue because it is reflecting the blue color. Since the ocean is blue, light reflects into the ocean the makes the color blue reflect into the sky. Some people might not believe this, but this is the real scientific explanation for why the sky is blue. Light is made up of different colors, but it is absorbed and blue reflects into the sky.

We learned in science that at one point, the ocean was actually green. It was when the Earth was just forming and the oceans started to form. The ocean was green because it had iron in it, which made the ocean green. When cyanobacteria started to release oxygen into the atmosphere, it caused the ocean to turn blue and that is why we now have a blue ocean. Just imagine, if we were there the sky would look green because the green color would reflect in the sky.

    How would plant fossils be found in Antarctica? If you think about it, it is really cold over there and there is like no sunlight over there. So how would you find plant fossils over there? These fossils were found there because Antarctica used to have tropical weather over there. We have been learning about Earth's past and learned that some places were really different back then. 

    If you think about it, back then the Earth was really different. Antarctica had different weather and climate. The tropical weather made plants survive there. The plant fossils could have been preserved in ice because fossils can be preserved in ice. Those fossils could be really old. We have learned about how fossils could be preserved and one of them was that fossils could be preserved in ice.

    In science and computers, we are making a website about an animal at the Chaffee Zoo. Our group got the Speke's gazelle. We also have to do research about it for our website. There were four different paper for the research. The papers are reproduction, classification, adaptation, and human interaction. I got human interaction and I can tell you right now that you don't want to get this paper.
    Human interaction is about what the humans are doing to the Speke's gazelle. The paper had resource as food, pollution, myths, zoo life and more. This paper was difficult because there was not a lot of information about all this stuff. I wish I got adaptation. The paper said to do only five or you could do more. I barely did five because there was not a lot of information about it. I asked Mrs. Poole and she couldn't find any information on this stuff too. What I got done was resource as food, zoo life, genetics, conservation efforts, and something else.

    I think that the greatest discovery in science was the discovery of DNA. As you all know, DNA was never known back then. One day a person named Rosalind Franklin heard of DNA and wanted to discover what it was. She used her x-ray diffraction system to help her in her experiments to find DNA. One day she had a clear photo of DNA which she called Photo 51.

    She also discovered two types of DNA, which she called A and B. If she had never discovered DNA, then we would know anything about ourselves. DNA contains genetic information about yourself. It contains you eye color, your height, and many more things. Then two guys named Francis Crick and James Watson made a model of DNA. They said DNA looked like a twisted ladder, and that was the model they made.

    Some people consider the discovery of DNA the greatest discovery in scientific history.
