One of the best reasons to lift weights is to reduce your risk of injury in daily life by strengthening your muscles and bones. Follow these safety tips to learn the proper way to lift weights to avoid injury. Lessons, information,...

In this lesson plan, students are introduced to the four forces of flight-drag, lift, thrust, and weight-through a variety of fun-filled flight experiments. Students will "fly" for short periods and then evaluate factors that might...

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...

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...

Students will make paper rockets, parachutes, and foam gliders to experience how objects move through the air. Explore topics such as thrust, weight, gravity, force, and lift through fun activities and stories and cutting-edge work done...

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...

The Illinois Institute of Technology lets students investigate the aerodynamics of a helicopter, focusing on the variables which effect the lift, thrust, drag, and weight. Students investigate the effects of aerodynamics on a wide board.
