Frog dissection
What would modern surgery be like if surgeons never practiced on other specimens beside humans. A couple days ago we did two dissections. One was about a frog and another was about a squid. This makes me appreciate surgeons because they take their time to be as careful as they can when they do surgery. If surgeons wouldn't of have done smaller dissections before they did a human surgery  they would put the person's life at risk. This is why they practice with something much less delicate and smaller before doing human surgery.
 
PictureThis shows how light is passed through the eye.
     We are going to learn how the light goes through the eye and how it is interpreted.
The first thing that happens is that the light strikers the cornea. Then it makes its way through a chamber of fluids behind it. After that it reaches the iris and the pupil. When the light passes through the pupil  to the lens, it's image is turned upside down. The image is turned right side when it passes from the optical nerve to the brain. 
    This reminds me of a quick activity we did using a light bulb, paper, and a small mirror, or magnifying glass. We you would move the magnifying glass and the paper and you would look at the paper you would see the image upside down. That showed me what happens before an image is sent to the brain from the optical nerve. 

 
PictureThe Alpaca from the Fresno Chaffee Zoo.
    Yesterday we visited the Fresno Chaffee Zoo. To be honest with you it wasn't as good as I had hoped it would be for certain reasons. Anyways, at the zoo we saw many animals. I wasn't that  surprised because I go to the Zoo a lot, but I did learn some new things. I was kind of shocked when I got to the zoo and saw the alpaca because it wasn't fluffy like I thought they would be. In reality they were about the size I had imagined  
     Then I realized they weren't fluffy because their wool had been shaved off. Even though the animal wasn't what I expected it would be, I still had a good time at the zoo, learning about the animals, seeing them, and taking pictures. But what I enjoyed the most about the Zoo was the bird show and the Sea Lion Cove. I liked the Sea Lion cove because you were able to look underwater and see the sea lions up close. I think this was an amaz

 
We have been learning in science about color, so today's blog is why do rainbows form. Well to make this easy to understand, rainbows form when the sun is near the horizon and there is a heavy fog, mist, or rain opposite to the sun. When someone stands between the sun and the rainbow they see colors. These colors are red, orange, yellow, green, blue, indigo, and violet. Well this is why after it rains, and the sun comes out, you see a rainbow composed of these colors. Red is always at the top of the rainbow because it has the longest wave length, and violet is always at the bottom because it has the shortest wave.

 
The previous post talked about why I thought the sky was blue. For homework we had to research this. To be honest I didn't do as much research because I had other things to do. Well I still did a little bit of research and the answer I got was this. The sky appears to be blue because the ocean water reflects on it. I think that this makes sense because  we are currently learning about light and reflection in the eyes in our sceince class. We have conducted some experiments to see this. So the bottom line is that the sky appears to be blue because that color stands out from the other and because the ocean water reflects on the sky.
 
This week we have been studying about color. For doing a brain pop activity I learned that the green grass looks grenn to us because that is the color that reflects to us; so the green wave is the one that shows. Today we are asked to answer, using what we have learned so far to answer the question above. So why is the sky blue. I may be wrong, but I believe the sky is blue because that is the color wave that shows or reflects. I think that to us it looks blue because the water color from the oceans reflect on the sky so the sky appears to be blue. Next week we will be learning in reality why the sky is really blue. So this means that if you really want to know why the sky is blue, you can look it up, or come back next week to read about it. 
 
We have recently been learning about fossils, Pangea, and other stuff related to that in science class. I'm going to try to answer the question as best as I can. So how would you explain why temperate climate plant fossils are
found in Antarctica? Well to start off fossils could be found in distint places around the world because of Pangea. Pangea is what people call when all the continents were clustered in together. Because of plate tectonics the continets slowly driffted away. However, back to the question, how did Antartica have a warm climate? Well as you can see in the picture (above), Antartica was near Africa, South America and India, where the climate was warm.
 
For my groups project : The Zoo Project, our group had to do research on an animal from the Fresno Chafee Zoo. My group chose the Domestic Alpaca. When we first heard the name we thought it was a bird because domestic means trained, but when we searched it up on Google we found out that it is actually a mammal. It is related to the llamas. Each person in my group had to do Classification & General; Reproduction; Adaptations; or Human Interaction. I did the Classification & General part.I had to research what was its scientific name and what it meant. I also had to research what their habitat and diet are. I also found out that their wool is used to make clothing because it is warm and water er
 
In my opinion I think the greatest scientific discovery was the discovery of DNA. I think this is the greatest one because it helped new scientist learn more about animal species and other scientific theories. I think that this is also an important discovery because it helped people understand DNA. Today in many science classes we learn about DNA. We learn about the people who discovered DNA, the structure of DNA, and we even did a couple of  projects that had to do with DNA. I explain a little more what kind of projects we did in a blog before. I think that overall the DNA discovery was very important.
