2020 Lesson Nine-The Brain

The Brain was fascinating to learn about! Our brains are the operating system for our body and are part of the central nervous system. Our brain weighs about 3 pounds and contains billions of neurons (cells that send messages to our body). There are several areas of our brain that control different functions on our body. It's important to protect our brain so that our body can function properly.


We looked at "Larry's" brain and saw the two hemispheres of the cerebral cortex.

We discussed the 4 lobes of the brain, the cerebellum, and the brain stem. We also talked about the jobs of each area of the brain. 

We learned about Phineas Gage who had an accident while working with explosives. An iron rod went through his head and brain, causing him to have a completely different personality than he did before his accident! Now doctors and scientists know the different areas of the brain affect different parts of the body, including behavior and emotions. 

Then we played some games, looked at optical illusions, and solved riddles to get our brains thinking!
