Last night I started watching American Genius on Netflix. American Genius, produced by National Geographic, features the stories of American inventors and innovators who were competing in the same field. The first episode that I watched was The Contest for Human Flight about the competition between the Wright brothers and Glenn Curtiss. National Geographic has an interactive timeline that complements the episode. In the timeline you can see archival videos of the first airplane flights, images of prototype drawings, and additional passages of text about the Wright brothers and Glenn Curtiss.
The Wright Brothers - The Invention of the Aerial Age is another good timeline for teaching about the developments made by the Wright Brothers. Dig into the Interactive Experiments section of the timeline and you'll find Engineering the Wright Way. Engineering the Wright Way offers interactive simulations in which students learn about wing design by joining the Wright Brothers for test flights in Kitty Hawk, North Carolina.
