This activity (located on page 3 of the PDF) is a full inquiry investigation into Bernoulli’s principle and airplane wings. Learners will design and build their own airplane wing models out of Styrofoam, record their mass, and then use a fan to measure the “weight” change when air flows over the wing. Results from testing other wing shapes and sizes are then measured to chart relationships between lift and wing size and shape. Relates to linked video, DragonflyTV GPS: Balloon Fiesta.
