science 4th grade pltw

In 4th grade PLTW we're learning about how air affects engineering. This is what we know about airplanes...

1. Air takes up space and has pressure.2. Air can flow.3. Fast moving air has lower pressure than slow moving air.4. Objects move away from high pressure and toward low pressure.

How do engineers test air? Wind tunnels!This video from NASA explains...

Check out how easy it is to observe the flow of air over a foil (wing) when you're using a wind tunnel!
