Written by: 
Tate Holbrook

Imagine being the size of an ant. Be careful - a face-to-face encounter with an ant would be scary and potentially life-threatening! But, if you avoided being eaten, you could learn a lot about ant anatomy from a close-up view. Ants have many body parts that are normally hard to see without a magnifying glass or microscope. And each structure has its own special function.

Whether a friend whispers in your ear, or you hear a jet flying high in the sky, sound is all around you. But how does a tiny sound wave change from waves in the air to sounds or sentences that we can understand?
