Mira's Science Blogs

Here is my groups' poster about the excretory system The project: Miss J.  assigned each group a body system. We were supposed to write and answer interview questions , write and present a compelling argument , draw a poster with our body system on it, and write an acceptance speech that we would present if we won the Oscars. This project was based on the Oscars. We made it sound pretty professional, and each group was competing against each other. At the end of all of the body systems' presentations  we are going to vote which body system is the most important and should win the Oscars. Summary: (Briefly explain what you learned) In this project I learned a lot about the urinary system which is scientifically called the excretory system. The main parts of the excretory system are the kidneys, the ureters, the bladder, the urethra, and the sphincter. The kidneys filter the blood. They take the waste out of the blood turning it into urine, and then sen

The nervous system controls everything that you do (walking, breathing, thinking, etc.) The nervous system is made out of your brain, spinal cord, and all of your nerves. In class we watched a video and learned about what the nervous system is and the different parts to it. In this blog I will be writing all about it. The system is called the nervous system because it is made out of billions and billions of nerve cells. The nerve cells are also called neurons.  Nerves carry messages to the brain and out to all of the other parts of your body. The spinal cord works like a highway where messages from the body go to the brain and back again.  Your nerves let you feel sensations. Ex. when your foot touches cold water it sends a message to the brain that it is freezing and your brain sends a message back to jerk your foot out of it. Your brain weighs about 3 po

We watched a video which was related to the topic and then we had to answer a question. The question was: " How do the muscular system and the skeletal system work together?" Well, read my blog carefully and pay attention to the skeletal muscles!  Well, first you need to know that  you have over 600 muscles.  You have three different types of muscles. There are skeletal muscles, smooth muscles, and cardiac muscles. They are either voluntary or involuntary. Voluntary means that you can control when the muscle moves and involuntary is that the muscle does its job without you telling it to. For example, when you  breathe,  you are using your involuntary muscles. When you are putting your hands in t

Summary: Website Link This week we were learning about organelles, cells, tissues, and organs. I learned that it all starts with the organelle and ends with the organisms. The organelles make friends (work together)in a cell. Then the cell makes friends (works together with other cells) and forms a tissue. Then the tissues come together and form an organ. Them all of the organs come together to make the organ system. Then the organ systems work together to make an organism. The organelles work together but they have their own jobs. For example: The chloroplast gets the sugars from the sun and the mitochondria makes it into energy for the cell. Cells that have the same job work together to make a certain tissue. You have skin cells form skin tissues, blood cells form blood tissues, etc. When tissues get into groups together, they make organs. For example, a brain is an   organ so it is made out of brain tissues. Your heart is made out of heart tissues. It is the same with
