LESSON 9: THE NERVOUS SYSTEM
Help your child understand how the brain and nerves work together to coordinate and control the body’s functions. Your child will also learn how their senses gather information and send messages through the nerves to the brain.
LESSON 10: BRAIN POWER: NEURONS
In this lesson, your child will learn that neurons are the cells that carry messages in their bodies and brains. Your child will also learn that the neurons in the brain provide many different pathways for messages to travel on.
LESSON 11: THE EYES HAVE IT
