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...

The airplanes unit begins with a lesson on how airplanes create lift, which involves a discussion of air pressure and how wings use Bernoulli's Principle to change air pressure. Following the lessons on lift, students explore the other...

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...

Students are introduced to the concept of simple tools and how they can make difficult or impossible tasks easier. They begin by investigating the properties of inclined planes and how implementing them can reduce the force necessary to...
