Studying the Nervous System

The Narwhals have begun studying the nervous system and the first step was to look at neurons. First we watched a video about neurons and  then made models of them using beads.

Next we read about the chemical reaction that takes place between neurotransmitters and hypothesized what chemicals in the body might be the best conductors of an electrical charge. We learned how to make an electrical circuit then tried water, salt water and sugar water to see which would be the best conductor. Ask a Narwhal about the results.
