Principles of Biology

About this site

A collaborative network linking Benton High School and MWSU via the dual-credit course: "Principles of Biology." Different than "publishing," we use this site to work and think "publicly." This is different. This changes what we do and how we do it. Feel free to poke around, see what we have going on...

This is Wordle's version of our course syllabus. It is a really cool data visualization tool for a body of words. Try it. Paste in some text and see what another *version* of that form of communication looks like:


I'll also post it in the "images" section so you can get a look at the detail.

What are Carbs, Lipids and Proteins?.. I can tell you!

"Structure and Function" is the very first thing I wrote down on my paper when we started our Chalk Talk; when I wrote this I really didn't understand how much I was going to learn over the next few weeks. We first started with writing down the word Capillarity, which is a property of water that causes water to rise above. We learned this to help us understand how water molecules work. Water is the base of mu… Continue

The fuel of Life


Technically I and you all are the same. Yes we may have different thoughts, feelings, and perspectives, but it’s what is inside of us that makes us so similar. It is what fuels us and gives us the energy to be unique that makes us so identical. It is the things like sugars, lipids, amino acids and nucleic acids that gives our bodies the power to live. Essentia… Continue

NO FATS – NO CARBS AND WITHOUT ANY PROTEINS! THAT’S WHAT I WANT!

Everywhere in our lives we get bombed with the newest diets and ideas to lose weight and live healthy. After the laws about the Nutrition facts labeling passed everyone should be able to judge if their food is healthy or not. But OH! Wait! There is just one Problem:
Who knows what Carbohydrate Percentages, Nutrition labels and boxes say about food? What is fiber? And why is everybody in the TV and in magazines telling me different stuff about fats and Proteins? There is one big rea… Continue

Carbs, Lipids, & Proteins. OH MY!

The last few weeks in Biology, we've been learning about bio-molecules and human nutrition. The main things we have talked about and taken notes (or Chalk Talk) on so far were carbohydrates, proteins and lipids and how they are all made up. I also found out that I was wrong about a lot of things, I had a lot of misconceptions about what I thought carbs, proteins and lipids were. I also had misconceptions about the diet plans, and diet pills and how they are all just a waste of money and time.

T… Continue

difference in "I want" and in "i need" ((THROUGH A WRESTLERS P.O.V.))

Today after practice when we were getting ready to get a beak down coach said something that brought me straight to our whole topic of carbs and fats and proteins. he was talking about how he has been where we are, having to cut the weight and keeping it in close range. the thing he said was "There is a difference in how much you wanna eat, just cuz its there and what you need or should eat" a few examples of his were say your at a pizza hut when your friends are skarfing on some pizza and your… Continue

Carbohydrates, Proteins, and Lipids.

Proteins monomers are amino acids; there are 20 different commonly known amino acids. Each protein is put together by different variations of the different amino acids. There polymers are polypeptides. Amino Acids get there finger print by their "R group" and they also have a carbonyl group. When in comes to Nutrition they have 4 calories per gram of protein. The best way to get protein is by eating foods with lots of protein in it. When you eat vegetables i… Continue

Nutrition

Nutrition is very important to the human diet. Here are some nutrition facts to help make a better decission on what you eat.

Carbohydrates are very important to the human body. Carbohydrates provide people with energy to get us through the day. There are simple and complex carbohydrates. The best foods you can eat are whole grains, vegetables, and fruits. There are 4 calories per gram.

Glucose is the most common carbohydrate. This gives you a quick burst of energy. This is not good when you n… Continue

"The Chemistry of Living Things"

Throughout the last few weeks of class, I’ve learned so much. From notes to our class discussions, so many things have been brought to my attention and changed my prospective on biology. Not only about the carbohydrates, lipids, and proteins but about how misleading the media is and how uninformed people are about their health, including myself.

One thing that I learned and that played a major part in the rest of the unit was I did not know that carbohydrates are sugars. I’m not sure what I tho… Continue

What is A Molecule Anyways?

Well a molecule is the simplest unit of an element. They ware important because they fuel our bodies in several different ways. We learn in class how we use some of these molecuse to fuel our bodies. The ones that we use that our class that we talked about are protiens, lipids(fats), and carbohydrates. you would think that all of these things are very similar because the are all made of the same three elements carbon. Hydrogen, and Oxygen. and in the past week I've found that they are all very d… Continue

Another Piece of the Puzzle?

Did you know that your body is like a puzzle; it is very complex and relays on every piece to create a complete product. There are so many pieces to this puzzle that many people don't quite understand, which enables them to get the picture, and that's okay. This not-so-complete picture has really became apparent in today's generation. Unfortunately, we have literally been fed countless misconceptions into what we can and can't put into our bodies. The fact of the matter is that it's not about th… Continue
