Summary
This week we were learning about the nervous system. 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 pounds (1.4 kg.) The main parts of your brain are the cerebrum, cerebellum, thalamus, and the brain stem. The cerebrum lets you think, speak, and move around. Your cerebellum helps you with coordination and balance. I definitely use that when I am at the gym! Your thalamus carries messages. Your brain stem controls your breathing, heart beat, and digestion.

I really enjoyed the video, and I learned some interesting things about the nervous system. I have realized that the brain is really complex and I would like to learn more about the different parts. I would also like to do some projects in class about the nervous system and the brain.


Here is the video that we watched in class about the nervous system

Musical Instruments and Sound- Weekly Blog (3/11-3/15)

Sound Energy - Musical Instruments by SolPass Summary We understand how sound is produced, and how sound waves can travel through different mediums, but how do musical instruments produce sound? There are hundreds of instruments in the world, producing various pitches, tones, and chords. There are three main types of instruments: wind, percussion, and string. The sound is produced differently based on the type of instrument. The first type of instrument is a string instrument. In a string instrument, the sound is created from the vibration of strings. For example, when you play guitar, you pull on the strings. As the strings vibrate, the air molecules start vibrating as well, producing sound. The next type of instruments are wind and brass instruments and are made when we blow sound into them. The shape and position of the instrument affect the overall tone and pitch. The most common kind of wind instrument is a reed instrument. Blowing on the reed causes it to vibrate, mak

The Food Chain (10/26-10/30)

This is an example of a land food chain http://www.sheppardsoftware.com/content/animals/kidscorner/foodchain/foodchain2.htm Summary: This week in class we started to learn about the food chain. We watched a video about the food chain, and then we had to answer a few questions. First you need to know that food chains always start with plants and end with animals. But remember, humans are animals. Humans are usually at the top of the food chain. But that does not means that they are always at the top, what if a lion ate the human! Then the lion would be at the top of the food chain. There are different types of food chains. If you want to see a full list then go to this website: http://examples.yourdictionary.com/examples-of-food-chains.html . In the video they talked about the ocean food chain. The ocean food chain is a food chain that happens in the ocean. Here is an example of an ocean food chain: phytoplankton (tiny little plants), get eaten by zooplankton (tiny animals

African forest elephants range from 2.5 - 3 meters in height, weighing from 50-200 pounds. Their color is usually brown and grey, and even though other coloring is possible, it is very rare. They live for about 60-70 years, which is quite a lot compared to some other forest animals. The African Forest Elephant lives in Central and Southern Africa, traveling through the forests and grasslands searching for food and water.  Why Endangered: The populations of these Forest Elephants is decreasing because of illegal poaching. The poachers kill the elephants for their ivory tusks to sell. They are also decreasing because of habitat destruction such as deforestation, which results in less food and shelter, which they need to survive. According to defen
