Unfortunately, I was unable to put the snowflake that I made on my wiki page, but just take my word for it that the snowflakes turn out really awesome.

H2O Electrolysis

Electricity is made when certain chemicals react together. We use electricity to power many machines. Electricity is also used to make chemical changes (if molecules in chemicals are changed, for example, sugar added to water). Electricity is stored in batteries.

H2O is an abbreviation for water. The H stands for hydrogen and the O stands for oxygen. The 2 in between the H and O is because there are two hydrogen atoms and one oxygen atom. Altogether, they make one water molecule.

“Lysis” means to dissolve or break something apart. Electrolysis means to break something apart using electricity. H2O electrolysis means to break water apart using electricity.

People use electrolysis for many things. You don’t always have to use water and electricity; you can use another chemical and electricity to make different things. Sometimes electrolysis is used to make metals like aluminum.

In this project, I will use electricity to split hydrogen atoms and oxygen atoms apart. As the electricity from the battery passes through the pencils, the oxygen turns into chlorine gas, and small bubbles gather together at the ends of the pencils.

The circulatory system is an extremely important part of the human body. It is the process in which the blood travels through your heart, into your lungs, and to each and every individual cell in your body, supplying them with oxygen. However, blood doesn’t just randomly slosh around. It flows through arteries, capillaries, and veins. It fills up chambers in your heart, then gushes into other chambers. There is a specific system for the blood flow that circulates your body. Your heart works very hard every day, powering the circulatory system. Blood carries oxygen from the lungs to the cells in the body. Most substances in the body that need to get from one place to another are transported by blood. About forty five percent of the volume of blood is red and white blood cells; the rest is plasma. Most substances transported by blood travel in plasma. Plasma is the liquid part of blood. It is ninety percent water; the other ten percent is dissolved materials. Plasma carries nutrients like glucose, fats, and vitamins. It can pass through walls of small blood vessels right into cells. Plasma also helps control the body’s temperature by moving heat from deep in the body to the skin, head, arms, and legs. Red blood cells are made by special cells in the spongy tissue called marrow, which is found in the bones. Every second, 3,000,000 red blood cells are made in the body, and at the same time, that many die. Each red blood cell lives only about four months. The red blood cell is the most common cell in the body. Each person has around twenty five trillion of them. Red blood cells have a chemical called hemoglobin, which combined with oxygen gives blood its bright red color. The second kind of blood cell is the white blood cell, whose job is to fight disease. There are many different kinds of white blood cells. Neutrophils are the most common. When germs get into your body, the white blood cells engulf them. White blood cells live only about two weeks. Pus that forms at the point of a wound is mostly made out of dead white blood cells. Most of the time when people get cuts, blood platelets and a protein made by the liver called fibrinogen cover up the hole quickly. With hemophilia, that does not occur, so the blood does not clot, meaning the bleeding does not stop. This can happen with very mild injuries. Hemophilia is very rare, and cannot be spread to others. In order to have hemophilia, you must be born with it. Sometimes, when people have hemophilia, the blood goes into a joint or muscle, which causes pain and swelling. People with hemophilia also bruise easily. Red blood cells carry oxygen to the whole body. A chemical called hemoglobin helps the cells hold on to oxygen. Hemoglobin has lots of iron in it. If there is not enough iron in the food you eat, you can develop anemia, which you can find out that you have through a blood test. This sickness makes you very fatigued. It also makes people feel like they barely get any sleep, even though they have gotten as much as they normally do. Anemia can be treated with the proper medication and diet. People take pills called iron pills, or eat iron-rich foods like steak and broccoli. If people eat too much of a chemical called cholesterol, after years, as they get older, a substance called plaque may start to appear on the insides of arteries. This is because they have high cholesterol. The plaque leaves less room for blood to flow, so parts of the body might not get enough oxygen. If the muscles in the heart do not get enough oxygen, you can have chest pains. If the arteries become completely blocked, the heart muscles are damaged. This is called a heart attack. Blockage of blood vessels can occur all over the body. If the same thing happens with the vessels that lead to the brain, you can have a stroke. There are doctors that can fix blocked blood vessels. A tiny balloon is inserted into the blocked vessel. The balloon is inflated with fluid for a brief moment, and as it fills, it flattens the plaque and allows blood to flow again. This surgery is called an angioplasty. Another way to fix blocked vessels is called a coronary bypass. A surgeon replaces a blood vessel with plaque with a new vessel from the leg. They take a blood vessel from the leg because they are very long. This surgery allows blood to flow through the new vessel, so blood can get to the rest of the body again. The lungs have air-filled sacs called alveoli, which are surrounded by capillaries. Oxygen that has been breathed into the lungs passes through the walls of the sacs and into the capillaries, where it binds to the hemoglobin in the blood. The hemoglobin helps blood hold onto oxygen. Capillary walls are made of smooth endothelium, only one cell thick. The walls have tiny spaces in them, which allow liquid to pass in and out of the blood, and waste products like carbon dioxide to move into the blood, where it will go back to the lungs to get resupplied with oxygen. When it is in the capillaries, blood moves much slower, allowing this exchange. After the exchange of nutrients, arteries, which are kind of like thicker capillaries, branch repeatedly, finally forming arterioles that are very small. The arterioles branch into even narrower capillaries to form a capillary bed that can pass through tissue. The heart muscles squeeze together and push blood around the body through tubes called blood vessels. It works nonstop, never resting or taking a break. It is about the size of a fist and weighs about ten ounces. Each atrium has a one-way valve that opens when the blood is pushed to the ventricles, then closes so the blood cannot go back. The right atrium gets the blood that has recently traveled through the body, which is oxygen-poor, and therefore dark red. When the blood enters the heart, the muscles of the right atrium squeeze together and push the blood through a one-way valve into the right ventricle. Then the muscles of the right ventricle squeeze and send a surge of blood into the pulmonary arteries. The ventricles are in the lower chamber of the heart. They are heavier and stronger than the atria. The muscular right ventricle pumps blood into the lungs. The other, even stronger left ventricle pumps blood to every individual cell in your body. A valve in the atrium opens when the blood is pushed to the chambers of the heart. The walls of the arteries have three layers: a waterproof inner lining, a middle layer of elastic tissue and muscle, and an outer casing. The main arteries are as thick as your thumb. The aorta is an artery, a type of blood vessel, which carries blood away from the heart. It is the largest blood vessel in the body. The blood leaves the heart from the left ventricle and goes into the aorta. When the blood leaves the aorta it is full of oxygen, which is needed in order for the cells in the brain and body to properly function. The right and left coronary arteries, which are leading from the aorta, supply the heart with blood. The left coronary artery is divided into two parts, so some people say that there are three coronary arteries. When the blood is in the left ventricle, it can get pumped through the carodid arteries to the brain, through the axillary arteries into the arms, or down to the aorta to the lower half of the body. The largest veins in the body are as thick as a pencil. They have muscular walls, a lot like the arteries, but these walls are a lot thinner. When people move, the muscles of the body press against the veins, helping the body circulate. The blood going to the heart through the veins travels at a steady speed. Two big veins called the vena cava give the blood to the heart. The upper vena cava carries the blood returning from the brain and chest; the lower vena cava carries the blood from the stomach and lower body. After the blood is pushed through the capillaries, it passes into blood vessels called venuoles, which turn into the veins, which carry blood toward the heart. The veins have valves that flap open then close to trap the blood and keep it from going backward. As you can see, your heart works very hard to circulate the blood in your body, and without it, your body would not be able to work. Your heart works so hard for you, and you should pay it back by exercising and not smoking. Keep your heart healthy, and in the end, you will be glad that you did!

** I have had clogged oil ducts in my eyes, and I named them and wrote poems about them. This was my first one, and I named her Stella. Here is the poem **

Oh Stella go away from me, I do not want you can't ya see, I think your awful actually, oh Stella go away from me.

You're making my life painful, if you go I'll be greatful. You're making my life blurry. Oh go away and hurry.

You got real big and heavy. Oh go away already. You've been here for a long time. Lets face it, you're past your prime.

I' ve tried hard to make you leave. You must think that I'm naive. But soon you'll regret coming. Oh, you don't know what's coming.

Student Council Speech

Hello, my name is Emma, and I am very happy to be speaking to all of you. Throughout the years, I think we have all gotten to know each other very well. So, I trust your opinion for whether or not I would make a good class president.

I think I would make a good president because I am very organized. For example, my mom is a lawyer. Whenever I am at her office, I organize her drawers, papers, and files. I also run things down to her assistant and deliver messages to other lawyers in the building.

I am also good at not interrupting people when they are talking. I listen to and remember important things that people tell me. If one of you comes up with a fantastic idea during a student council meeting, I promise it will be one of the number one things on my mind.

I study and work very hard in school and at home when I am doing my homework. It is very rare for me to have late homework. I do not like putting things off or waiting until the last minute to do something, and normally do my homework early so I can have the rest of the evening off.

I think everyone in this class to help the school. I want to make this school even better for the students that will not be graduating this year. This is out last year here. Don’t you want to make it the best? Don’t you want this year to be awesome? I know that we can make that happen. Vote for me!!
