The Science of Airplanes
Have you ever watched airplanes overhead and wondered how they stay up instead of falling down? An airplane is a machine with stiff wings that moves forward very fast because engines push it through the air. Because the wings are shaped to make more pressure under them and less pressure above them, the airplane is lifted up into the sky. is a machine with stiff wings that moves forward very fast because engines push it through the air.

Uses of Airplanes
People use airplanesairplanes crossing the sky, think about the strong wings and engines working together. to travel, carry packages, and do important jobs like rescue or research, so they can reach faraway places quickly. Next time you see
