Charles Darwin was a scientist who had a theory and discovered natural selection and evolution. He traveled the whole world, and had a journal with him, taking notes about what are different or peculiar. However, this didn't mean that he did all this alone. He learned from other scientists, and mixed those with his theories and predictions. A scientist helped Charles Darwin understand that evolution went very slowly. He learned that over generations or decades, evolution has developed little by little. This could be affected by environment, or changes in the earth that the species lives in.


Charles Darwin didn't discover natural selection by himself. He had much to learn from when he first started this discovery. To me, it's mostly a shame of how most people don't note that other scientists helped Charles Darwin. They just thought that he did it by himself, even though it was completely different. Sure, he inspected and created his collection, but did he know what they were gonna be used for? Yes, he did. But did he know where to start? That leads to the extra help from the other scientists.
 
The Grand Canyon demonstrates crosscutting and superposition because of the way it's rocks is shaped. It can be due to weather effects like erosions or something else. 
   
Crosscutting and superposition affect the Grand Canyon because everyone should know that the Grand Canyon didn't naturally look like it was now back then. Back then, it must've been solid ground like every other mountain or canyon. However, as time pasts on, crosscutting and superposition has started its effect little by little. It also messes up the rock layers. Superposition only works if the rock layers are not bothered, however, if the layers are bothered in different ways, like folding, then superposition would definitely not work.
 
Many people used to believe that dark peppered moths were changed because of the pollution at the time. However, is this really the reason why they changed? Just because of pollution?
          Studies show that the dark peppered moths were dark, not because of pollution, but because of natural selection. Natural selection is when two organisms of species mate in a natural way. Scientists were very confused as to why there used to be a few dark peppered moths, but ever since pollution came, tons of dark peppered moths started to appear. It turns out that the dark peppered moths were attracted to the dark forests that were caused by the polution. In conclusion, pollution caused the dark peppered moths to change, and develop.
 
Limited resources and overpopulation can be a big problem. First of all, limited resources can mean many things. It can mean limited food, limited water, limited anything! In most cases, food is the problem. All species eat the same things as another species does. For example, birds and some mammals eat insects. If there were limited insects, and an overpopulation of birds and mammals who eat insects, what would happen?
       In this case, I think that evolution comes to view. While this competition goes on, some systems in each species' body might have an effect on this. For example, a dog. Has a dog always been like the species we've seen today? No, because it is proven that dogs were originated from wolves. We've all should've heard or known that a wolf has been domesticated as a pet a long time ago, so over generations and generations, the wolf has slowly changed into the dogs we see today. In fact, there's a huge variety of dogs now. 
       Would humans like today change as well? That's a question that no one can know. However, many things in life change. Whether it's an animal, or a resource, or a tree, or whatever. This doesn't mean that the changes are always good, but if we keep doing what we do best, then we will make a good chang
 
During 2nd quarter, somewhere near the end, Mrs. Poole had us do a DNA key chain project. It was really fun, and the class had a great time. 
          First, we had to pick our assorted beads. I don't remember how many, but I do know that we had to pick green, blue, gold, red, white, and yellow colored-beads. The yellow and white beads were circular beads, while the rest were rectangular. We also had to get our strand of wire. Next, we inserted one of each bead in a particular order, because each bead represents a base and an element of the DNA. After that we created the base for the key chain all together. Then we inserted our bead patterns. First of all, Mrs. Poole always said that blue and gold always together, and green and red always go together. After that, you add a white bead and a yellow bead to each side. Then, when the pattern is done, you go and make it into a loop, then insert the loop wire string into the rectangular bead. You do the same to the other side. Then you gently pull the two strings together and as you pull, notice that they attach.

If you just keep repeating these steps over and over, then eventually you will have your DNA keychain. It's also a good way to see how it develops.
 
Over the past 2 quarters, we've been doing Quizlet flash cards. We're given a paper with the list of things that are needed in the flash cards. However, it is our job to find the definitions. 

I think that Quizlet is a good way to learn. By looking for the definition in the book, we learn it better because searching for the definition is something that we're going to do for tests. Think of it this way: you're in the middle of a test and a word from your Quizlet comes up. You try really hard to remember it, but it doesn't work. However, when you search really hard for it, you'll eventually find the definition. You see, I think that searching in your brain is sort of like searching for something in your textbook. Also, Quizlet let's us play some games. We can match them, type them, or memorize them. It's like an online study guide! 

In conclusion, I think that Quizlet is one of the better things to use for studying. You can make your own to study, or you can use someone else's. Quizlet helps you learn more, even by creating a list yourself!
