Minute Physics recently published a great new video about jet engines. In Why Are Airplane Engines So Big? viewers can learn why jet engines have gotten larger over time, why they biggest engines don’t always go on the biggest or fastest airplanes, and the basic principles of jet propulsion. The video briefly explains the mathematics involved in determining at which point an engine becomes too big or too small to be efficient. It is a fast-paced video so your students may need to watch it a couple of times to catch everything.
Last year I had the privilege to fly on an A380. The A380 is the largest commercial jet in the world. As I saw the plane towering over the jetway in Dallas I couldn’t help but be amazed at the engineering that makes it possible for something so large to fly across the Pacific in one shot. The explanation can be found in a Minute Physics video that Airbus recently sponsored. How Do Airplanes Fly? explains the roles of wings, propellers, turbines, and wind currents in making a plane fly.
These videos could be the basis of a flipped science lesson. In this post I provided an overview of how to use five services to create flipped video lessons.
