Chapter 1: Have Fun with Your Senses!
Your brain is the boss of your body. It tells your muscles what to do. But before it can decide what position to put your body in, or where you should walk or run to, it has to know what is happening in the world around you. That’s what your senses do. They send messages to your brain, telling it what is happening around you, so your brain can figure out what to tell your muscles to do.
YOUR SENSES AND YOUR BRAIN ARE PALS
Your brain and your sense organs—your eyes, ears, nose, tongue, and skin - work together to make sure that you are safe. They also help you make the body movements you need to survive and to enjoy your life. If the air is cold outside, your brain reminds you to put on a coat before going outside. But how does it know if it’s cold outside? With your eyes, you use yoursense of visionto read the thermometer, so your brain knows what the temperature is. By sticking your hand out a slightly open door for a few seconds, you use your skin, yoursense of touch,to feel what the air is like outside. With your ears, yoursense of hearing,you can listen to the weather forecast on the radio.
