Express Yourself!
Two circles representing faces, one with a circular a mouth signifying surprise, the other with a mouth and furrowed brows signifying a frown.

When you're feeling happy or sad, it's often written all over your face. And the person looking at you knows exactly how you feel!

Humans are very social animals. And facial expressions are a way for us to communicate our emotions with one another, even if we don't speak the same language. Communicating our feelings helps us get along. That's one reason our brains evolved the ability to make facial expressions, and to instantly recognize them in others.

Play this game to see how good you are at recognizing emotions!
