Today, Atticus wrote a explanation of how the nervous system disease, ALS, also affects other body systems. We discussed how your body has to receive a stimulus before it can respond to a stimulus. This is why we have senses: touch, taste, smell, hearing, sight. Atticus brainstormed how the body senses and responds to stimuli before it responds by moving/thinking/etc. We read about two vocab words: the sensory system and receptors. He underlined the words and definitions, then wrote and illustrated them in his science notebook.
