Do you know who Charles Darwin is? Charles Darwin is a naturalist who helped find evolution. Todays blog will be mainly about the people who helped him find a conclusion to evolution. There are many people who helped him. One person is Charles Linnaeus. Linnaeus helped Charles by inventing taxonomy. Another person is Matthias Matthias invented classification. There are eight levels of classification. Finch birds also helped Darwin find out how they have evolved. Darwin used many resources to help him find out evolution. He also traveled a lot. He traveled for five years. He went everywhere he could to study the evolution. You are probably thinking what form of transportation that he used to travel. Well he used a ship called the "Beagle".
I hope that you have learned more about Charles Darwin than you did not know before. If you are more interested in finding out more about Charles Darwin and evolution, click on the button links below. If you have found any other important information, share it with someone and let me know too, by commenting! Did you know he wrote books as well? Well, until next Science Solution's blog post!
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. To learn more about crosscutting, click here. Until next time!
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.
Todays blog will be about Punnet squares, and what they are used for. First of all, a Punnet square is a chart that shows different possibilities for someone or something to look like. It lists all the possible genotypes for your child, or anything you want to see the outcomes of. Geneotypes, can be Bb, bb, or BB. A phenotype is your physical appearance Now, if I did not well describe how Punnet squares look like, they look like a square with a vertical and horizontal line right in it. At the top and side of the Punnet square, you put the father's and mother's genotype of whatever it is that you want to see the possible outcomes of. For example,if the father's genotype for brown eyes would be Bb, you would put that at the top or side of the Punnet square. If the mother's genotype for blue eyes was bb, you would put that on the top or bottom of the Punnet square. Once you have figured out the two genotypes, you are ready to find out the possibility of the offspring. This is why people use punnet squares to find out how their offspring would look like.
This is it for todays blog. I hope that you have learned a couple of things or two about this science lesson. If you really pay attention to punnet squares, you start to get the hang of it. Punnet squares are really just a chart showing all the possible genotypes for the offspring. To help you out a little bit more, just remember these vocabulary words: phenotype means your physical appearance genotype is the letter of your appearance and a punnet square is just a chart listing all of the possible genotypes for that particular thing. This is what we are currently learning in Mrs. Poole's science class.
Today is Science Solutions Tuesday. In this blog, I will be blogging about how to make the DNA ornament that we made about a month ago. First, you need different colored beads. The beads will represent the bases, and sugars, and everything that is inside the DNA. Then you need wire, the length of a yard. The last thing you need is optional, you may need a plastic bag, to keep all of your pieces in. The second step is to put seven of the different colored beads on a wire, this is a kind of a hard step to do, because then once the seven beads are put on the wire you need to loop it to the other side, and grab the other wire and loop it to the opposite side of the wire. This is kind of hard to explain. After you have done this the next steps are to repeat this step again until you have as many rows as you want. When you are done, the next step is to loop both strings though the middle, and pull them as hard as you can. Once you are done with that, you cut what ever is left of the wire off. The last step is to twist the ornament, so it will look like a double helix.
This blog explaines how to make this, and the materials you will need to make it. Step number two was pretty tricky to explain, so I hope you understand this concept that I am trying to make. Like I had said before, it was not easy to explain, so try to Google " DNA bead ornament , and that will possibly give you a better described idea. This is it for today, and I hope that you have learned something new and cool.
Today's post will be about the hardest lesson that I have encountered over the past semester. That lesson is learning the parts of a cell. When my science teacher first taught us the parts of a cell and where they we located, it was pretty hard for me to memorize them all and know were all of them are. After a week, she started to talk about the parts all the time so I kind of got them. Finally, Mrs. Poole introduced the cell cake. The cell cake is a cake that you have to design the parts of a cell and label them. At first I did not feel good about this project, because I knew little about the cells, but when I opened the science book to see how it looked like I started to read and understand the book more, and more, because I always had to glance at the book to really get a feel of what this cake is going to look like. Once we made the cake, I could already tell were all the parts are and what they do. The more I was really focusing on this project, I knew more and more about the cell. Now I can name some of the cell parts and tell you what they mean.
The lesson that I have learned from this was to never give up and to really focus on something you are not really sure of. I really like to do projects like these, because it helps me learn more and more, than just getting a book and reading almost half of it. I feel that if more and more teachers start to do "hands on" activities, then you will see more children and adults start to pay attention and really memorize all of this. This is how I know were all the cell parts are and what they do.
Today is Science Solutions Tuesday. In this blog I will be blogging about an artical that I have read on the physics of Santa Clause. The first thing it said was how Santa Claus could deliver presents to everyone in the world? The answer was: if you count all the children in the world there would be over 324 billion, however because Buddhism Jewish, and other religious don't celebrate this, there is now about 324.5 million kids who do celebrate. Another question was how can he carry so many things in his sled, If every kid wants a medium size bag of legos, that would be over 300 tons, not including Santa himself. Then at the same time his reindeer magically "fly" in the night sky, and the earths gravity is strong Another question was about his reindeer How could the possibly "fly"? Answer: there is still 300,000 species of animals that have not been discovered, so that was the answer for that.
So? What do you think after these statements that I have told you, do you think Santa Claus is real? I guess until we find out, the world may never know if Santa Claus is really real or not. If you ever come across some evidence that you read in an article, don't be afraid to share it with somebody. Who knows you might have uncovered a huge piece of evidence!
Today is Science Solutions Tuesday. In this blog I will be blogging about a special step in mitosis, Interphase. Interphase is when a cell duplicates it self, so that way, there will be more cells like it. It is almost like making copies of a paper. Interphase is also another word for replicates. When you replicate something, you make copies of it. So today I will show you how Interphase does its job.
First, the cell copies by having its chromatids copied. Chromatids are two strands of DNA. Chromatids are put together like an "X" figure. To have the chromatids copied, they need to be all over the place. So, that is the first step of having interphase,. This is mainly the part of interphase. It just copies chromatids. Once the chromatids have been copied, it is another step in mitosis.
