Weekly Blog : Victor Nguyen 7A Image Image Locatio n Summary Since this week was the last week, before Holiday Break. I had to answer many questions about genetics. I learned that DNA is a molecule that contains the instructions which helps your cells function. I learned that genes are the instructions manual for the body to make proteins. There's is about 25,000 genes. Chromosome is the units of DNA. A human hold 46 chromosomes. There are thousands or different kinds of proteins. Genes are the blueprint for making proteins. Heredity is the passing of traits from traits from parent to child. There are about 23 chromosomes, that each parent pass to their offspring. Traits are a notable feature of quality. Finally, each parent gives 1 of their allele to the baby, so the baby gets 2 alleles. As you can see, I didn't much this week. S&EP7 - Engaging in Argument From Evidence I used evidence to defend my explanation. The last two periods of this week (and year),

Charity Fair Project Blog: Victor Nguyen 7A Image  Our group presenting, the Night of Charity Fair This is our trifold. Summary To start off, my first year here at AdVenture, and first time doing Charity Fair, was a new experience for me. My group, Ian, Pierson, and I chose to help PetSmart charities, by making kale chips. I learned that we should always work as a team, whether we are at school or at home. When we were looking for the charity statistics, we learned that not all charities will post past tax and revenue information. While working on the test product, we learned that he we needed to change our unit of measurements, from ounces to tablespoons. Personally, I have learned so much from doing this project, from choosing a charity, finding different costs and statistics, thinking of an item to make, making a test product, presentations, and to putting all the money into a special cause. I learned one big thing,  Practice Make Perfect. Backward Looking Du

Human Body Redesign : The Immune System http://www.huffingtonpost.ca/dr-jennifer-pearlman/boost-immune-system-flu_b_8205274.html Body System Function:  The immune system help you healthy and stay alive. For example, if there's any cells in your body that will hurt you, make you sick, or even perhaps endanger your life, the immune system will attack it.  Organs: Skin: This helps prevent things from entering your body. Mucus from nose:  This helps prevent the things that inhale from entering your body. Stomach Acids: This kills bacteria from the food you eat. White blood cells:  This recognizes all the invades/germs in your body. Thymus:  This is where the  lymphocyte matures .  Bone Marrow:  This is where bone cells are produced. Spleen:  This is the forming part of the immune system. One Organ's Structure and Function: Personally, I think the main function of the immune system is the the bone marrow. The bone marrow is the where the bones c

Human Body Redesign : The Respiratory System www.livescience.com/22616-respiratory-system.html Body System Function:  The respiratory system is like the circulatory system, a system of transporting. The respiratory system bring oxygen to the body. It also helps get rid of the carbon dioxide.  Organs: Diaphragm : a  muscle that works with your lungs to allow you to inhale Lungs:  It is where all the oxygen is processed to be carbon dioxide.  Trachea:  This allow air to pass  through. One Organ's Structure and Function: Personally, I think the main function of the respiratory system is the lungs. When I hear the word lungs, I think this organ is very important, because in order to breath you need lungs. Lungs can easily be harmed if you use it improperly, like smoking. The lungs is where all the oxygen is processed to be carbon dioxide, so now the respiratory system will release it. As you can see, I think the main function is the lungs. Interactio

Human Body Redesign : The Nervous System http://www.netdoctor.co.uk/conditions/brain-and-nervous-system/a10463/living-with-parkinsons/ Body System Function:  The nervous system is about action and senses. The nervous system is whole reason why you're able to do things.The nervous system helps you sense your surroundings. It helps you sense things that might be coming your way, like a car, and tell you get out of the way. As you eat, your nervous system will start to digest and release hormones. As you can see, the nervous system is mainly about action and senses.  Organs: Brain: It coordinates all your actions and thoughts. Spinal Cord: It help tract and pull away your muscles based on thoughts and reflexes. Neurons: It helps send back-and-forth the messages throughout your body.  One Organ's Structure and Function: Personally I think the main function of the nervous system is the the brain. I think this because the brain coordinates your thoughts

Human Body Redesign : The Urinary System http://www.stanfordchildrens.org/en/topic/default%3Fid%3Danatomy-of-the-urinary-system-85-P01468& Body System Function:  The urinary system is a system of filtering. When you are thirsty, you drink beverages. Where does the liquid go? In your urinary system. In there, chemicals are going inside the liquid and the water is getting cleaned. After that, your liquid waste goes out, when you're in the restroom. Organs:  Kidneys: Two organ s  that filter waste from the blood and produce urine. Bladder:   A sac that keeps your urine. Ureters: Its takes the urine from the kidney to the bladder . Urethra: It carries the urine out from the bladder, when you urinate.  One Organ's Structure and Function:  Personally, I think the main function o f the urinary system is the bladder. I think this, because the bladder is sac that keeps your urine. You kinda need a bladder to hold your urine. The bladder's shape,

Human Body Redesign : The Digestive System http://kidshealth.org/EN/images/illustrations/K-digestive-275x267-enIL.gif Body System Function:  The digestive system's job to break down food. When you are hungry, you eat food. Where does that food go? In your digestive system, where all the food gets broken down, all into a pulp. after that, it travels through your intestine and then to our stomach. So, the digestive system break down food. Organs: Esophagus:  It squeezes food down into the stomach. Stomach:  Stores food. Food is turned and mixed with enzymes.  Intestine:  This is where food is absorbed. One Organ's Structure and Function: Perso nally, I think the main function of the digestive system is the esophagus. I think this because the esophagus helps squeeze the food down into the stomach. In order to get food down into the stomach, you need an esophagus. Without it, the food be going somewhere else, or would be staying in the same place. Even

Human Body Redesign : The Muscular System http://www.interactive-biology.com/3373/the-muscular-system-how-we-move-around/ Body System Function:  The muscular system's function is movement. The muscular system helps you move, whether you want to or not. You don't have control on most of the muscular system. That's called an organ called, involuntary muscle. Voluntary muscles are under conscious control which means, it moves based on y our  mind. So the muscular system help you move. Organs: Voluntary Muscle:  This is found in other organs. It's job to move substances around the organ. Cardiac Muscle:  This is only in the heart. It's job is to pump blood throughout the body. Smooth Muscle:  This is only voluntary, which means it move consciously, which moves on your mind. One Organ's Structure and Function: Personally, I think the main function of the muscular system is the cardiac muscle. I think this, because the cardiac muscle helps p

Human Body Redesign : The Circulatory System Circulatory System Body System Function:  The cardiovascular system is a cycle that moves blood from your heart to every part of your body. It's also a transportation that carries chemicals to your points of your body. So the cardiovascular system is a transportation that moves chemicals and blood.  Main Organs: Heart: This is a muscle that pumps blood through your body. It handles 3 types of circulation. Aorta: Receives oxygenated blood pumped from your heart. Veins: Leads circulatory fluids back to the heart. Blood: Circulates in the arteries and veins. Capillaries: Vessels that allow most of the transfer of compounds and dissolved gases. One Organ's Structure and Function: Personally, I think the main function of the cardiovascular system is the heart. I think this because the heart is like a power source. In other words, hearts make energy for the human body. With the heart, it creates blood. Now

Human Body Redesign : The Skeletal System Skeletal System Body System Function:  The bones in the skeletal system is like a frame, or structure. It helps your muscles and organs connect. The skeletal systems is also an act of protection. This helps protect your skull and most of your internal organs. So, the skeletal system is like a frame and is protection. Major Organs: Bones: The skeleton is made up bones. Bones help you move your muscles. Ligaments: These are tough tissues that connect one bone to another. Tendons: This is equally tough tissues that connects your bones to your muscles. Cartilages: T his  protects the bones from rubbing against each other and creating pain. Joints: This is where the bones meet. Structure and Function: Personally, I think the main function of the skeletal system is the cartilage. I think this because the protects the bones from moving around. In other words, it helps you move. Just because you have bones, do

Weekly Blog : Victor Nguyen 7A Image Image Location on Wikipedia Summary This week I did some pretty cool and interesting things. For example, we started to learn about osmosis, or movement across membranes. Osmosis is when one solution has a higher/lower concentration on the inside or outside. After doing the Day 1 worksheet, we did the Day 2 worksheet. In the Day 2 worksheet, we observed eggs that were in vinegar for a day, the beginning weight, and then put it into different solutions, like water, salt water, corn syrup, and the original solution, vinegar. The next day, we realized that mainly all the eggs decreased their beginning weight. In addition, the look of the eggs changed from a little to a lot. For instance, some of the eggs were small and glowing to puff and darken. When we learned about osmosis, we also learned about hypotonic, hypertonic, and isotonic. This means, when there more solutes, on the inside, outside, or the same. Now, it our turn. Each group

Weekly Blog: Victor Nguyen 7A Image I didn't take a picture of my foldable, so heres the link to this photo:  https://www.youtube.com/watch?v=YO244P1e9QM Summary This week I did many things. For example, first the first 2-3 class periods, we started to learn more about Biomolecules. There are carbons, that forms a total of 4 bonds and can form straight chains, branched chains, or rings giving living. There are also organic compounds, which is a compound that contains carbon. There's carbohydrates,  lipids, protein, and nucleic acids. Each of these biological molecules are made of one or some of these elements, carbon, hydrogen, oxygen, nitrogen, phosphorus, or sulfur (CHONPS). Each and every of these biological molecules has a monomer. Carbohydrates's monomer is saccharide. The monomer for lipids is fatty acid. Protein's monomer is amino acid. Lastly, the monomer for unclean and is nucleotide. For the last 2 class periods, we made a foldable with descripti

Cell Wars Project Blog: Mitochondria  Image  Summary This week, I have learned  plenty of things. For instance, I have learned about 8 different organelles when we watch the videos. My organelle was the Mitochondria. My organelle produces the energy of ATP. It has a double membrane. The other seven organelles, are Cell Wall, Cell Membrane, Cytoplasm, Chloroplast, Golgi Body, Lysosome, and the Endoplasmic. I learned that some organelle only help plants, some only helps humans, and some do both. For those organelles that help plants, some protects plants and things, like bacteria from going inside of the plants. For those organelles that help humans, some protect humans. Some also gives human energy and protein to help us stay healthy. As you can see, this week, I have learned  plenty of things. Backward Looking I probably knew some things before this project. For example, before this project, I knew that there were cells, and organelles. I knew that there are plant

Weekly Blog: Victor Nguyen 7A Image Location Summary This week, I have done plenty of things. For example, at the beginning of the week, we were supposed to continue working on our Cell Wars project, but things got out of hand, so everybody started to assessments from the 7th grade Life Science textbook. After two class period of working on our bookwork, we finally went back to doing our Cell Wars project. Remember, my group and project is the Mitochondria. Our function is to produce the energy of the ATP. After many days of research, we started to do our poster, that wasn't so great and wasn't so bad. We turned it and got it back to hang on the wall. All is left, is to record our video. We didn't know what to record, so we thought of song, play, or showdown. Some of our peers decided don't, So we are currently trying to record the song and put the video together. As you can see, this week I have done plenty of things. SP2 : Developing and Using Models Just

Weekly Blog: Victor Nguyen 7A Image Image Location  Summary I learned many things in the past week. During, the do now, I learned that atoms is the fundamental structure of the orange juice, because the orange juice is non-living after the orange has been squeezed. There are two types of observations, quantitative and qualitative. A quantitative observation is observing the weight, length, etc. of an object. A qualitative observation is descriptions of an object. I also learned about organelle. My organelle is Mitochondrion. That organelle is doubled-membrane. As you can see, I learned many things. SP1 - Asking questions and defining problems This week, I was working with my organelle group. I formulate testable questions when I asked, "How does Mitochondria help humans and help plants?" Some other people also asked, "Where is the Mitochondria cells located?" As you can see, I chose SP1 because I did ask scientific questions, and also with m

Weekly Blog : Victor Nguyen 7A Image Image Location Summary This week, I learned a variety of things. For example, I first learned what the scientific method is. The scientific method is a series of steps that follow when performing an experiment. Then, I learned about the manipulated and responding variable. A manipulated variable is what you change during an experiment. A responding variable is what changes during an experiment. After that, we learned the difference between an observation and an inference. Lastly, we learned about cells and atoms. Cells are the smallest structures that make up all living things. The cell is basic unit of structure and organization in organism. All cells come from pre-existing cells. As you can see, I learned a variety of things. SP1: Asking Questions and Defining Problems This week, with some of my table group partners, we ask some scientific question, like 'Is this a manipulated or responding variable?' There were some times w
