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...

Simple machines allow us to do difficult tasks like lifting objects heavier than our body weight. In this science project you'll build a tabletop lever and measure how much effort it takes to lift an object by altering the length of the...

Water creates a lot of energy, just look at the Grand Canyon. In this science fair project, you will demonstrate the power of water by converting the kinetic energy in moving water to mechanical energy, which will lift a small weight.

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...

Do you know how an airplane flys? Use this challenge to learn about flight by building a wing that can generate lift from a fan while carrying weight. Find details about the challenge, tips, and a lesson plan on this site. Also, students...

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...

Did you know that an ant can lift 20 times their own body weight and that an ant's brain has 250,000 brain cells? You will find more interesting and out of the ordinary facts about ants in this enlightening site.
