**//__Aerobic and Anaerobic Exercises__//**

As you exercise, oxygen breaks down glucose into water and carbon dioxide which is a
====process called aerobic respiration. This process only happens during aerobic exercise like running, not during anaerobic exercises such as swimming. When you exercise your cellular respiration increases and needs==== ====more amounts of oxygen. Aerobic exercise is exercise that has a long duration but has low intensity. Our blood then takes oxygen to the cells and takes carbon dioxide back away from the cells. The blood takes the carbon dioxide to the lungs and it is breathed out into the surrounding air. This==== ====means that the more you exercise, the more you need oxygen. In the end you will need to breath out high amounts of carbon dioxide. There are two different types of exercise, anaerobic and aerobic; these two types of====

====In order for one to understand how this increase takes place you first need to understand how the body’s heart rate is controlled. Our heart rate is controlled by the sensitive division of the self-directing nervous system.==== ====As you exercise, you put weight on your nervous system which activates self-directing response. Then the brain will gesture your heart to beat faster. This must happen in order to present oxygen to your muscles so that====

====Breathing is a bit more intentional. In the times that you rest, the brain is involved as it uses the level pH in the bloodstream to figure out the level of carbon dioxide and increases the necessary inspiration. However,====

==== Science is a way to learn about the earth. Scientists collect information and explore the earth using science processes. The first process of science is **observing**. It means to use one or more of your senses to gather information. There are two different ways to observe. The first is **quantitative observation** which deals with numbers, or amounts like height and weight. The second is **qualitative observation** which deals with descriptions that don't have to do with numbers like that a bird is blue. Then, there is **inferring** which is the second science process. Inferring is when you explain or clarify the objects you observe. They are based on information you already know about the subject. The third process is **predicting** which is a statement or claim about something that will happen in the future based on past experiences or evidence. **Classifying** (4th process) is grouping items that are alike in various ways. As an example, in a data table, Dr. Earle's team grouped together different types of algae. After that, you **make models**. Making models includes creating representations of complex objects or processes. Certain models can be touched while some are equations or computer programs. The 6th process of science is **evaluating** which is comparing observations and data to get to a conclusion about them. Lastly, you do a **scientific investigation**. First you ask questions. Then you have to find out a way to answer the question. After that you do the actions needed to be done to find the answers. ====

__ Questions: __ In a Paragraph or more tell the class your Interests, favorite subjects, favorite topics in science, least favorite topics in science, and what you Would Like to Learn This Year. =I like to sing, I dabble in computer engineering, and every once in a while I go outside to shoot hoops.= =My favorite subjects are math and science, while my least favorite one is P.E. In science I enjoy black= =holes, weather, experiments, and a little human body. I don't like matter and rocks. I would like to learn= =about "Sedna the tenth planet". Is it true?=
