2 DAYS UNTIL THE CRUISE! Today we will be talking about super position which is basically the layering or rocks or just layers. The layers, which are basically rocks, sand, dirt, and minerals slowly were laid on-top-of the Grand Canyon and built the Grand Canyon themselves. As time went on, the layers slowly pushed the big formation down, creating a ditch. This is why the Grand Canyon is a "canyon." Have you ever caught that? If you look close enough, you can see where super position has effected this earth. A lot of canyons, rivers, and trails were built this way. If you look close enough, just a little closer, you'll find something. In fact, try this, try to find 3 places where super positioning has effected this earth. you can google it, ask a teacher, or even if you have a picture or live by one1
That was supposed to be a joke up there, so hahaha! No? Alright, that's cool. Well, welcome back! I'm super (not) excited to be back in school starting off a wonderful educational week! Today, I am writing on Peppered Moths and how they, well, changed. Peppered Moths were found in Europe a little bit around the time when manufacturing was just being introduced. They were studied and after a while, scientists started noticing that they seemed to be changing color from white, to a dark peppered looking color. After studying more, scientists evaluated that the pollution in the air form the manufacturing was causing the peppered moths to change color.
An interesting thing thought about peppered moths that scientists also found out was that light-colored peppered moths were more likely to survive in a light-colored forest than darker moths. It was the same for darker-moths in a dark-colored forest. It sounds really understandable to. Like a bunch of square blocks stacked on-top-of each other with one triangle on top, we all know the triangle is going to stand out more. The problem was, light-peppered moths, were being used as lunch for some really hungry animals in the dark-colored forest called... just kidding there's no "monster."
Evolution. Sounds like a type of lotion if you ask me, but some people believe that Evolution is how us humans began. Others believe God created us, but for today, we will be focusing on Evolution.
Lets say we're in a jungle and food has been dying and poison and disease has spread. Okay, now what? Well, this may sound a little disturbing but it's also what can happen at any time, too. Some animals are forced to eat each other and others mate. Mating with other animals like a wolf and a fox (just an example) could possibly give you a hunting dog. Most likely not though, that was just an example. Through mating, and living on, other species could be created. A lot of people believe that Evolution was how mankind was created, through monkeys. After all, we all can act like monkeys at times.
No matter what you believe, Evolution is a very cool subject to study and I really enforce it. It's cool to think how certain animals came to be and how much they change our society. Thanks to evolution, our zoos, T.V. shows, and our imagination has grown. Think about what is going to happen in the future. Think about what movies would be like if there was no such animal as a gorilla, or even a dog? Where would our world be today, as of 2013?!?!?!?
In science class with Mrs. Poole, my class and I have recently been studying genetics, traits, and characteristics. We worked with Punnett squares, pennies, and lots of charts just to figure out possibilities that could be inherited. At first, my mind was buzzing. Our craft tools were set upon the table in a box. There were scissors, pennies, and tape. We were making a family! Out of some paper! Woohoo! There we lots of different ways that your family could look like. Some had square eyes. some had circle. Some had round eyes and some had square. Some had square teeth, and some had pointed. There were many different ways "characterize" you family... just you had to use a penny. Let's say T is for tall and t is for short. Heads is dominant and tails is recessive, you flip a heads then another heads. So you end up with TT which meant your child would be quite tall.
I learned a lot from this experiment and honestly it helped me. I think future students would really enjoy doing this just as much as I did! Now I know about genetics, genes, and traits!!!
And I'm back! Sorry for not writing yesterday, you know those orthodontist appointments! My teeth are so sore! It really stinks! Anyways, today I get to write on Punnett squares. Nope, not Punent squares... that's not even a word!
A Punnett square is used to show traits that can be inherited from two parents, to their offspring. Punnett squares are really useful even though they are simplified to the max. A Punnett squares are easy to make and use as long as you now the difference between dominant traits and recessive traits. A Punnett square is a square divided into fourths. It very simple they way Punnett squares work so don't stress like I did.
Let's say this,
A woman with brown eyes (dominant trait) married a man with blue eyes (recessive trait) and eventually had kids. What are the possibilities that their child will have blue eyes. Make a Punnett square! The possible genotypes for the mom could either be BB or Bb. The dad would have to be tt because he has a recessive trait. So on the top of the Punnett square put BB (we will do the "Bb" trait later). Remeber that the BB trait is for the femaleand the bb trait is for the male. You can draw pictures to help remind you of who is who! Can't wait to see what you find!
DNA as an ornament?! Really?! How nerdy and strange and kidd-ish. Well, if that's what your thinking... stop! In science, a few weeks ago, we made DNA ornaments for our Christmas tree. Making them was wwwwaaaayyyyy more fun than sitting down and studying for a test. We were given wire, beads, a bag, and a cloth. Each of these tools each had their very own job that was needed in order to make the ornament turn out how it needed to look. The cloth, was used to keep track of the beads when using them. The beads were small, round, and glass. So they could get lost and break really easily. The cloth, for me was really useful and I am glad I had it when using the beads. The bag was used to keep track of the string and the beads when not being used. Our name and period were wrote on the bags and then placed into a basket titled "Period 6." The beads, like I mentioned, we glass, round, and small. So they could easily break and get lost or as some students would've said, "ran away." The wire was thin, sharp, and curly. It curled up easily and was hard to keep straight when sliding beads down it. This project was fun for me to do. I liked this project because my class and I got to touch and work with small beads and compare them to even tinier things. We referred to certain beads to certain parts of DNA and compared our DNA with real DNA. I think this project was very useful and should be used
Science really is full of explanations and math. Science, is full of much more than that though... what about our solutions!?!?!? Science has always been a really tricky class for me. I don't know what makes it so hard, but I just can't seem to get all the concepts! They just don't click! One of the trickiest concept for me to understand were cells and their parts. Cells have many parts, and what makes it so tricky? You have trillions of cells in your body, which millions double/triple the parts inside them, alone the DNA. In science, we did a project that I think, didn't help me, but got me happy and excited; so I was more open to understand and learn. My group and I, made and edible cell. It was so good! You can see it under my classes if you click on the "Science" page. We used candy and foods everyone in my group agreed on for the parts of a cell. I had a blast, and it helped me a little, which, being me, is a lot of help. I also studied my work. I looked over what I had learned from my group's edible cell, workbook pages, and homework questions! I was smart, Asking questions are great when you don't understand something. In fact, study! That's another thing I did. I did it hard, but I learned a lot and remembered all of it! Even if your stuck on one of the easiest science, math, or english questions in the world! Ask! Who's knows what that will do?!
Ever since you were a kid you always had your parents saying "You should ask Santa for that." or "Put it on your Christmas List! I'm sure Santa will read it! Now that your older though, do you ever think about whether the fat man with the white beard is real? I mean, that's what everyone says. Have you ever doubted it? Ever wondered if anything so mind-boggling is real. You've been told so, but I think its time to find out. Don't you?
To get scientific, we would have to use a series of numbers. Here we go!!! There are about 3 million children that are under 18 (that through religion [and other stuff] can have Christmas) in the world. They receive gifts from "Santa." Look at this though, there are houses all around the world each holding a different amount of children. If Santa has to travel around the world in 12 hours... he's moving at an average rate of 2 seconds per house. Maybe even less!
Then, look at Santa's sleigh. With Santa eating all those cookies (from all the children around the whole earth!!!) ... he would weigh about 5 tons. Not counting the toys, and the reindeer; If reindeer were real, which could be possible through animals and genetics. All that weight is going 2 seconds around the world in 12 hours!
So... as you can see. Unless there is a 5 ton, fat, white bearded man living in the North Pole (below freezing) there is no way there could ever be a Santa Claus. Of course there are possibilities, like magic, but with being in 2012 and going into 2013, there is a serious doubt about it! Just the only problem now, is... who brings the presents!?!?!?!?!?!?!?!?!?
Ok, it has to do with DNA. Done?! Nope! Here's how this process works. When DNA replicates, it replicates through a series of stages; like growth. When you were born, you were called an infant. Once you turned three the word toddler came about. Once your about fifteen to sixteen you are a teenager. You get the idea? So anyways DNA goes through these stages. A quick way I remember these stages are "IP MAT C " I stands for Interphase which we will be talking about today. The P stands for Prophase and the M stands for Metaphase. The A and T are for Anaphase and Telophase. Last, the C is for Cytokinesis.
Interphase is the first stage to DNA and its replication process. During Interphase a cell grows to its fullest size and (technically) clones its DNA. The DNA is replicated, so the next cell(s) get the exact amount the parent cell had. That's pretty much it and how DNA is replicated during all of the stages. It grows then replicates.
So next time your teacher needs a report on Interphase, you'll know what to do! Good luck! Just remember "IP MAT C" and you'll have it DOWN!
What does DNA really stand for? How about, Dad's Not Active, or Dad Never Ate. Nope DNA stands for a really long word!!! We all know DNA is inside your body, but what's inside the DNA?! Picture this, you have your body, then your skin, then your muscles, then your bones and body parts, then we get to the really small stuff... the cells. Inside cells is where the DNA "lives." Inside the nucleus is where the DNA stays in an eukaryotic cell. In a prokaryotic cell, the DNA just floats around in the cytoplasm. Not only to cells and our body's have parts, so does DNA. DNA has little parts too! In DNA you'll find a lot of the same things like sugar, phosphates, and some other stuff. DNA looks like a twisted ladder and lives inside us. I sure don't know what I'd do without my DNA! Thanks
