We finished our frog dissection last week on Friday. We started our dissection on Wednesday. On Wednesday we broke the jaw and we looked and studied the mouth. On Thursday we opened up the frog's chest. On Friday we took out the organs of the frog. I personally did not like the dissection all that much. I have science 8th period so when I walk; I smell 5 dissections in that room. The stench is terrible! Also, I am a vegetarian so the stench was very disgusting to me since I do not eat meat. I wish we had two gloves instead of one glove. Mr. Kirste was giving out two gloves to all the students. When he got to our period, he was low on gloves and we had to use one glove instead of two. We then had to touch the frog. I felt very sad for the frog during the dissection because these frogs were once alive to, and they were killed against their will so some middle schoolers will learn about frogs.
I don't see the importance of having to dissect a frog. How will dissecting a frog help us become better mathematicians? It won't help us. The only possible way it could help is if you become a surgeon when you get older. I don't see any other benefits. Also, the frog population is decreasing exponentially. Killing some frogs so they could be used in science classrooms is not helping us save frogs. In fact, it goes against helping and saving the environment.
There was only one Radiated Tortoise at the Fresno Chaffee Zoo. It was the first exhibit we saw when we got to the zoo. When we saw the Radiated Tortoise, it wasn't doing anything. Our Radiated Tortoise's shell didn't look like most of the pictures we saw, some of them were similar. The Tortoise seemed like it was old. The leopard tortoise looked more like our Radiated Tortoise, but there were some differences. We saw the giant tortoises at the zoo, they were actually moving, and they were very big, that explains where the got their names from. I wish there were more Radiated Tortoise. There were some animals that were abundant, and then there were some animals which there was none of them. Our tortoise does not like too much heat, and yet it spent most of its time in the Sun based on what we saw, but we only looked at our tortoise for about 4-5 minutes because we had to look at other animals to. Our research seemed accurate based on what we saw. The Radiated Tortoise also had a companion which was the Fennec Fox.
I really wish there were more tortoises at the zoo. There was also only one red footed tortoise, and they didn't even put that group's poster up. There were two African Spurred Tortoises. There were about 12 stingrays at the zoo. That is much more than 1-2 tortoises. There were like 30 flamingos at the zoo. There were only 2 Asian elephants. I wish there were more, and only one tiger!
Most amphibians lose their tails when they go through metamorphosis. The salamander is an amphibian which does not lose its tail. Frogs and toads are examples of amphibians which do lose their tail. Amphibians means double life and, double life means that most amphibians spend their early life in water. When they are adults, they spend their adult life on land. Before amphibians become adults, they go through metamorphosis. When going through metamorphosis, their body changes. Their lungs, circulatory system, and their digestive system all change. There skeletons become stronger to support the pull of gravity.
Most amphibians lose their tails when they go through metamorphosis. A counterexample would be the salamander is an amphibian which does not lose its tail. Frogs and toads are examples of amphibians which do lose their tail.
Light first comes in contact with the cornea. The light we see is coming in from the pupil. That means that the light passes through the pupil after passing the cornea. The light then is refracted by the lens. The refracted light shines on the back of the retina. An upside down image is formed on the retina. The optic nerve then reverses the image which makes it right side up and sends the images to the brain.
This path is very simple it is: cornea, pupil, lens, retina, optic nerve, and finally the brain. This is all there is to it. Also, the cornea refracts light as well. The iris around the pupil gives us what we call the color of the eye. Certain animals also have a moonshine. This helps certain animals see in the dark. The light shines on the back of the retina, some of the light shines back and out the pupil helping certain animals see in the dark.
