I’m currently reading Bill Bryson’s book, One Summer: America, 1927. The book is centered around significant events of that summer including Charles Lindbergh’s crossing of the Atlantic. Airplanes have come a long way since Lindbergh flew in the Spirit of St. Louis, an airplane that he couldn’t see out of when looking forward. The physics of how an airplane gets airborne and stays airborne are still the same as they were 1927. A newly released video SciShow Kids uses excellent visuals to explain how an airplane flies today. The video uses both jet-powered airplanes and prop-powered airplanes to show the key concepts.
How Airplanes Fly is the latest video that I’m adding to my growing list of resources for teaching and learning about airplanes and airlines. Those resources are included below.
Turbulence: One of the Great Unsolved Mysteries of Physics is a TED-Ed lesson that explains what turbulence is and the forces that create it. The lesson explains that even though we typically associate turbulence with flying in airplanes, turbulence exists in many other places including oceans.
How Things Fly
hosted by the Smithsonian features an interactive module in which students design their own airplanes. The activity starts with a simple and slow airplane that students have to modify until it reaches a target speed and altitude. As students modify the wings, fuselage, and engines of their airplanes they are given instant feedback on the effects of those modifications. In some cases the feedback includes the airplane crashing and the students having to start over again.
Here’s some archival footage of Yeager’s flight in the Bell X-1.
If you have ever wondered why airlines sell more tickets than they have seats on an airplane, the TED-Ed lesson Why Do Airlines Sell Too Many Tickets?
is for you. In Why Do Airlines Sell Too Many Tickets?
you can learn about the mathematics that airlines use to maximize the revenue that they can generate from each flight. That math includes calculating the probability that everyone who holds a ticket for a flight will actually show up for the flight. The way that probability is calculated is explained in the video. Finally, the lesson asks students to consider the ethics of overbooking flights. Watch the video below or go here to see the entire lesson.
