Learners revisit Bernoulli's Principle (Lesson 1 of the Airplanes unit) and learn how engineers use this principle to design airplane wings. Airplane wings create lift by changing the pressure of the air around it. This is the first of...

Learners begin to explore the idea of a force. To further their understanding of drag, gravity and weight, they conduct activities that model the behavior of parachutes and helicopters. An associated literacy activity engages the class...
