Have you ever heard of sexual reproduction and asexual reproduction? Sexual reproduction is where you reproduce sexually. Sexual reproduction is for multicellular organisms like humans and animals. Many organisms have parts that they can use to reproduce sexaually. Mostly humans and animals have these parts. When you reproduce, you create offspring, which can be children. Asexual reproduction is where only one parent makes offspring

Asexual reproduction is only for single celled organisms. Like bacteria and protozoa. Those organisms only have one cell and are not as complex and multicellular organisms. These organisms cannot reproduce sexually like humans and animals. Instead, they reproduce by themselves. Asexual reproduction only has one organism instead of two because those organisms don't have those parts like humans. Instead they have different parts. They also create offspring, but not from two parents. Instead, it is only one parent.
 
 
In science, we did a frog dissection to helps learn the parts of a frog and kind of get an idea of where the parts are. The frog dissection was really fun and helped me learn where the parts of a frog are. This kind of makes you think of how surgeons do surgery on people who need it. It kind of gave me an idea on how surgery really works on people with the frog dissection. It makes me think that some surgeons probably dissected something in their life to get an idea of how surgery works on people.

With the frog dissection, it gives you an idea of where the parts are. If you learn this, it might help you learn where the parts of a human are. If there was no practice on surgery, then we would do everything wrong. I bet some of the surgeons out there started by dissecting something to get an idea of how the human body looks like on the inside. If there was nothing to practice on, then the surgeons wouldn't know what to do, or how to do something. That is why we need to practice on something first to get an idea of how to do this.
 
 
In science, we learned the parts of an eye an light. We learned about the parts of the eye an how light goes through the eye. First light is reflected of something. The light goes through our eyes. First it goes through the cornea. Then it goes through the aqueous humor. Then is goes through the iris. After that it goes through the pupil and then into the lens. After the lens it goes through the vitreous humor and the goes to the optic nerve where the brain focus the light and makes an image.

For this unit of science, it was really difficult at first because there were so many things to learn and cram into our brains. We first learned about light and how it is reflected and refracted. Then we learned about the colors of light. After that we started learning about the parts of an eye and what are there functions. This part was really easy and I knew the parts of an eye. After that, we learned about the electromagnetic spectrum. She gave us a little trick to help us remember the electromagnetic spectrum. First is radio waves and then microwaves. After that is infrared waves and then visible light. After that is ultraviolet, then x-rays and then gamma rays.
 
 
Yesterday we had zoo day and I can say that it was kind of boring. My group and I got to see our animal, the Speke's Gazelle. I then realized that the scientific name was wrong, and it was Gazella Spekius. That was our first mistake. With our research it said the scientific name was Gazella Spekei. Then it said that it lived in dry grasslands, and we put something else. It made me feel bad that we had mistakes on our research, and I thought we had the worst website, but I'm sure other people had mistakes too.

Our research was kind of off because we got different things than what the zoo said. Even though we got some things wrong, our research was pretty spot on. I hope many people learned new things about our animal and hope that someone will help it survive. Some of the things we got right was that it was endangered and that it lived in Africa. At least I was happy that we got some things right and didn't get the whole thing wrong. Some things that we got wrong on our research was the scientific name of the animal.
 
 
Have you ever wondered what makes a rainbow? You see them when you spray the hose and see the mist and the rainbow together. How does that rainbow form? Rainbows form by the reflection of water droplets in the air. When you see the mist, the water droplets are reflecting the colors in the spectrum. Those colors make a rainbow. A rainbow is an optical phenomenon which means that the rainbow isn't really there. It's kind of like a projection of colors reflected into the light.

You usually see rainbows after a storm. The main colors in a rainbow are red, orange, yellow, green, blue, indigo, and violet. We called these colors in science ROYGBIV. These colors are in the spectrum of light. When you use a prism to separate the colors, you will see that a rainbow will form when you use it. The colors are ROYGBIV from the spectrum. There are some legends about rainbows. I'm sure everybody has heard that if you go to the end of a rainbow, you will find a leprechaun and his gold, but that legend is not true.
 
 
I have talked about this topic before. Some people wonder why the sky is blue. What is the real scientific reason for why the sky is blue. As you may know, the sky is reflecting the color blue into our eyes because it absorbs all the other colors except blue. The sky is blue because it reflects off the ocean and we look at the color blue in our eyes. As you know, the ocean is blue because it contains oxygen in it. At one point in history, the ocean was actually green.

There is also tiny droplets of water in the air. Light hits those tiny droplets of water and reflects into our eyes. Way back in history, the ocean was actually green. There was a lot of iron in the ocean which made the ocean green. When cyanobacteria started releasing oxygen in to the atmosphere, it cause a reaction and made the ocean turn blue like today's ocean. Just think about it. At one point, the sky could of been green because the light reflects into the sky. I kind of wish we did have a green sky.
 
 
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.
