In this article, it explains why there is no Santa Claus or if there was, he's dead now. It explains many factors of Santa's journey that could really prove that there is no Santa. Here are some of the key things he wrote: 1. There is no known reindeer species that can fly. 2. For the number of Christian kids there are, Santa would have to park, hop out, jump into the chimney, lay down presents, eat a cookie, drink milk, climb up the chimney, hop in, and take off in about 1/1000th of a second. 3. If Santa ate a cookie and drank an 8 oz. cup of 2% milk at each house he visited, he would gain about 225 calories per house, and a total of 20,655,000,000 calories, which is about 2950.7 tons. That's impossible. You should read the article yourself, with this link.


There are some possibilities that Santa Claus is real, though. I read another article with a counter argument against this article. It does have some information that can bring down the chances of Santa not being real. Some things said in this article were: That there is a possibility that flying reindeer could be found, since there are about 30,000 species of animals yet to be discovered. There are some physics on how he go at the speed of light. Nobody knows Santa's metabolism rate, and there is some information that brings down the percentages of house he has to deliver two. Another fact I read was that some Christmases are celebrated December 25th, and some on January 6th, bringing down the number of houses flown to, the number of cookies eaten, and the speed. Read these responses yourself in this article.

That is a very good question, with a not so complicated answer. DNA is what has the instructions for your cell's nucleus, or your genes, in other terms. But how do they replicate? Well, as you know there are four kinds of bases to DNA, and DNA has a double helix shape ( See my The Structure of DNA blog post if you don't know ). But what does that have to do with DNA replicating? I'll tell you what. DNA replicates by pretty much unzipping itself. It breaks the bond between the two bases, and unzips itself. While it is unzipping, with the help of proteins, new nucleotides are put together with the loose ends. It keeps doing this until there are two chromosomes now. Each new DNA has a new strand and an old strand.

Mitosis is a process in which a fully mature cell splits into two daughter cells, making whatever organism containing those cells slightly larger. Mitosis is broken up  into phases. Each phase has a different part of mitosis. The interphase: The interphase is what stage most cells are in. It is the phase that takes up most of the cell's life. At the end of the interphase, DNA is replicated. Next comes the prophase: It is when the DNA molecules condense. The nuclear membrane and nucleolus are now no longer visible. Next is the metaphase: When the chromosomes align themselves at the equator of the cell. Then anaphase begins: This is when the two DNA strands separate and move to opposite sides of the cell. Then comes the second-to-last stage, telophase: When a nuclear membrane forms around the chromosomes and a nucleolus forms in each nuclear membrane. Then comes the final stage, cytokinesis: It's the stage in which the cell splits into two new daughter cells. 

This process takes from 1/2 to 1 1/2 hours. If you feel that I excluded some things, please comment on this post. Make sure to also check out my other Science Solutions blogs and my Science Digital Portfolio! Thank you!

The structure of DNA was a very big discovery in the science community. It wasn't known until after World War II, not that long ago! DNA consists of not very many parts, that I will be explaining today. First let's start with nucleotides. They are the combination of a sugar, phosphate, and a base. There is always one sugar and one phosphate, but the base varies. There are four different bases: adenine, thymine, guanine, and cytosine. These two pairs always paired up with each other. The amount of thymine is always an  equal amount of adenine. Same for guanine and cytosine. Last but not least, DNA is shaped like a twisted ladder, or double helix, which is the correct term.

Every type of cell has a different strructure, or looks different. Today, we will be discussing the differences of plant, bacteria, and animal cells. They're all different, believe it or not. Animal cells, our cells, are ovalish( Yes, that's a word ) and fat. They have all the organelles any other cell animal cell would have. Now a plant cell, they're a different story. They are tight together, looking almost like bricks. They can do this, because they have a cell wall that protects the cell. Plant cells don't need very many things outside of them because they can make they're own food, but animal cells, sadly, cannot. Most bacteria only have one cell, that is why it is hard to see them. That cell has everything the bacteria needs to survive. Those are your three types of cells.

Every year Mr. Kirste, a 7th grade science teacher, and Mrs. Poole, my science teacher, do a project with the class called Edible Cell. In this Edible Cell project, we create an edible thing to represent a cell and its organelles. Sometimes they wonder, should we continue with this? The reason why they think this is because after creating the cell, you have to answer one question. Mrs. Poole or Mr. Kirste would point at an organelle, and ask you what it does. Unfortunately not many people were ble to reply to that question. I strongly believe that it is a very good idea, and a fun way to learn and remember cell parts. I liked it. I think that it is a really good way for students to learn the vocabulary. Sadly, it doesn't show that when the test scores come up.

Cell are the basic unit of your body. Inside cells are these little things called organelles. They are the tiny little parts of a cell. Today I'm discussing about only three of them. The first one is going to be the nucleus. It is the jelly like substance that is surrounding the nucleuos, which is the brain of the cell. It itself is sort of the brain. it regulates, or tells the other cell parts what to do, all of the activities that go on inside the cell. The second thing we are going to discuss is the chromosomes, or DNA. It is placed inside of the nucleus. Its job is to help the nucleus know what to do, because the DNA holds all of the traits of that cell and person. The last thing we are going to discuss about is the cell membrane. It is pretty much the barrier between the cell and its surroundings. It's very flexible and thin. It controls what gets to be put out of the cell, and what gets put in. 

Cell organelles cand be very difficult to learn and remember because of there hard names or hard explinations to them. Do you have any tricks to remember them? Please comment on this post of what you know about cell organelles. Also check out my other Science Solutions Blogs and check out my Science Digital Portfolio under the My Classes tab. Thank you!

I'm in Mrs. Poole's class, and she doesn't like rats. But Mr. Kirste, the other science teacher for 7th grade, has many snakes and rats in his classroom. So even though I don't go to his class, I still know some pretty coll stuff that they do. One of there latest projcts was to measure a baby rat's tail length, head circumfrence, and bdy circumfrence from birth. I asked my friends about it, and from the information I gathered, this is my conclusion of what happened: Of course, the baby rats grew a little bit every day. But about every three days you can see that there was a significant change from three days before then. The rats also grew rapidly, a lot faster a human does because their hormones are much quiker than ours. The length of the tail was what grew the fastest,and the body faster than the head. The babies are know quite mature, but not yet fully grown. This is the information I gathered from friends and conversations, so it may not be 100% acurrate, but pretty close.

I've done many different activities in Science Class, but my favorite one so far was... the microscope activity! First we took a test on the different parts and their purposes on the microscope.Then we listened and watched Mrs. Poole demanstrate how to properly use the microscope. Then we did it for ourselves. My partner and I chose which slide we wanted to examine, out of the many collorful ones there were, and we began the process of magnifying it. First we put the slide under the stageclips. Then we put our eye to the eyepiece, then we started moving the coarse adjustment knob to see where it focuses in the best. After that we moved the fine adjustment knob , to fine tune the image  of the slide. It was all blue, purple, and pink, and it was showing very little cells. We did this with a few different slides, making sure we absolutely knew what we were doing.

What I learned from this activity was how to use and know what parts and their purposes on a microscope. I never was taught about the different parts of a microscope , until Ms. Poole had taught us. I didn't even know how to use a microscope, let alone know what the big thing on top of it was called. I'm very excited that I can know use and identify the parts of microscope, because know I can use in class, and everywhere else where I need to use a microscope. Please check out my other Science Solutions blogs, and give me some feedback on what you think about the blog and your opinion on the subject. Thank you! 

  Two days ago in science class, the teacher, Mrs.Poole, handed out some papers about volume and measuring. I thought I wasn't going to be able to do the different volume problems. Volume always seemed like something that is just one of those things, where you just really don't understand it. Then the Mrs.Poole told us that the way to get the volume of an object, is to multiply the width by height by length. It started getting a little easier then. Then Mrs.Poole told us to go around the classroom and measure all of the different objects, or boxes, and find there volume around the room. I was a little nervous that I would get an answer wrong and get it wrong for my whole group. But then it became easier and easier, until I wanted to measure and calculate all of the boxs' volumes, because it just got fun. And I made very few mistakes on that worksheet. Just doing a physical activity with the lesson really helps me learn the curriculum. I already love math, and when there are numbers included in science it gets easier for me. Thankyou Mrs.Poole for making science easier and funner for me to learn and understand.
