Why is my hair straight when my friend's is curly, does my tummy growl when I am hungry, do things start to look all fuzzy when they get close to my eyes? Nothing fascinates kids more than their own bodies and how they work. The youngest budding scientists can find out some of the head-to-toe basics through these extremely simple activities. Using tea bags, children can test their sense of smell--and find out why they stop noticing even the most delicious aromas after a little while. With a pillow, a helpful adult, and a supported headstand, they'll discover why they become dizzy when they spin. Who knew learning could be such fun?
