The shape of our ears helps us to catch sounds from the air. The sounds then go into the hidden part of our ear, inside our head. Ears help us to be alert about things that happen around us. We can't move our ears, but animals like rabbits can move their ears to help them catch sounds.
Why do we feel dizzy when we spin?
Inside each ear, we have three loop shaped tubes with watery liquid in them. When we spin, liquid spins too. Special nerves send message to the brain about the spin. If we stop suddenly, the liquid continues to spin around for a little longer. Our brain gets confused and we feel dizzy.
What is your belly button?
Everyone has a belly button. What is it for? Your belly button is the place where a special tube (cord) joined you to your mom before you were born. This cord could bring you oxygen and food to keep you alive and growing while you were in your mommy's tummy. You didn't need mom's food after you were born, so the tube was cut and the place it was attached to made a belly button.
