Have you ever heard of or went to the Grand Canyon? If not, the Grand Canyon is a place where there is a lot of rocks and huge mountains  The Grand Canyon is a pretty hot place. This blog is about how the Grand Canyon demonstrates superposition and crosscutting. The Grand Canyon demonstrates this very well, because of how old it is. If you were to take the Grand Canyon apart layer by layer, you would know by looking which layers are the oldest. In some cases, you can tell how old the item was by looking at how many layers it has. Superposition means that the rocks were put there naturally. Crosscutting is a fancy word that means cutting through the rocks.

           I hope that you learned two new vocabulary words, and there meaning. It is easy to remember crosscutting, because the word cross and cutting really give it away. To learn more about superposition cliick here. Just to let you know, the Law of Superposition just states that the rocks were put there naturally.

     Have you ever heard of the Peppered Moth? The Peppered Moth is a type of moth that lives on a special type of tree. That tree helps them camouflage from birds. Peppered Moths got their name from their appearance. They look like your normal moth, but they have dots on them that are the color of the seasoning pepper. Their color protects them from birds like I said before, because they can camouflage in tree bark. A bird is more likely to eat a beige color moth than a dark colored one, because the beige colored one stands out on a dark colored tree bark.Peppered Moths are very rare. At first, people did not really notice them. They probably thought that it was an ordinary moth. One day, a person noticed a Peppered Moth and told other people. Then other people noticed more Peppered Moths, and to them they were really common.

   This is what Mrs. Poole taught us. She gave us a small packet and told you to watch a power point on it. After that, she talked to us a little bit more on this topic.If you want to learn more bout this or want to see the power point, click on the buttons below to activate the link. If you learned any thing else that is very cool about peppered moths, tell me. Well, until next Tuesday!


 
     Today is Science Solutions Tuesday. In this blog I will be blogging about how overpopulation and limited resources can lead to evolution. First of all, you need plenty of resources to feed and take care of a town. If the town does not have that, the town will slowly die off, because they do not have those resources  The resources can be items like: water, land, and food. Overpopulation can also led to madness  This can create competition, because people will be fighting over supplies that they do not have. Death may occur if they are arguing about this. People may end up killing people to get food or steal for their family. Like I had said earlier, overpopulation can be a result of competition. If you really think about it, a town full of people can not feed on two cows and one gallon of water. Overpopulation means that there are more mouths to feed. This leads to limited resources  because the town will be eating or drinking everything there is. This leads to evolution. Evolution means every type of that certain species will go away in that habitat. In other words, the species that is living in their habitat can not get used to it, therefore it may die. Many things can not get used to their habitat or environment  Sometimes it is hard to get used to new things.

Evolution is what we are currently learning in my science class. Do you know about evolution? Do you think it is a hard thing to understand. I hope my blog post will help you understand evolution, overpopulation, and limited resources mean. Just remember, overpopulation means that the town or place is too crowded. Limited resources mean that you have little to none of the materials you need. The last definition Evolution, just means that something can not get used to their environment or habitat. These definitions will help you understand why overpopulation and limited resources will lead to competition. 


 
      Today is Science Solutions Tuesday. In this blog, I will be blogging about the Paper Pet Family Portrait that we did in my Science class. The Paper Pet Family portrait has something to do with geneotypes and genetics. A genotype is a trait that you inherit from your family, so in this portrait, we made pets that have somewhat the same characteristics from their parents. Lets say if the father has pointed eyes and the mother has round eyes, what would their offspring have round or pointed eyes? To figure that out, you need to make a punnent square. For this activity, we found out the mother and fathers genotype. An example of a genotype is Bb, bb, or BB. When we find out their genotypes, we have to put the mother's and father's genotypes in a punnent square. For example, if the father had BB pointed eyes and the mother has bb round eyes, then when you put the genotypes in a punnent square, the possibility of their offspring having pointed eyes would be 100%, because all of their children would be heterozygous. So once we found out what that offspring would have, we would draw pointed eyes on the child. We would do different characteristics for each one,such as: eyes, hair, teeth and nose. Once we would find and draw their characteristics on the child, we would paste on the children and their parents on a paper, and there you go, there is a beautiful portrait of the family.

This helped me learn genotypes more, because I actually visualize this concept. Physically visualizing math, science, history, or any lesson can help you  understand more. Please check out my science page under the heading titled "My Classes". There you will find more information and you will see a picture on how this really looks like. I hope you learned something new today.
