The purpose of this lesson is to understand how the brain receives and sends signals to the body. Until third grade, children view organs of the body as individual parts, e.g. the eyes are for seeing; the stomach digests food. At this level students are ready to start viewing the body as one whole system. One way to ease into this view is to study systems within the body such as the digestive system, circulatory system or the nervous system. This lesson introduces the brain, but not just the brain. It emphasizes how the brain interacts with the rest of the body. Students will learn about this by understanding “messages” that go from parts of the body to the brain, and vice versa. At this age it is less important for students to memorize scientific terms.
This lesson focuses more on answering questions and helping students realize the “job” of the brain and the nervous system in regard to the body as a whole.
