The principles of levers and simple machines are presented here. An easy-to-make lever is constructed by each group of scientists, and they use it to explore how this simple machine makes heavy things so much easier to lift and move. A...

The lever is an everyday simple machine. Youngsters learn the principles of levers and explore their many uses. Groups of pupils perform a simple lab where they lift objects with a fulcrum while placing the load in a variety of...

Here is an inventive plan that should get your young scientists excited! In it, groups of pupils test out the work done by six different simple machines. The machines are: the wedge, the lever, the inclined plane, the pulley, the screw,...

The principles behind pulleys, levers, and simple machines are the focus of a science lesson plan. In it, learners take part in a whole-class activity. There are two groups of pupils who each must lift objects with fixed pulleys and...

What's the best way to use a simple machine to solve a real-world problem? Scholars construct their own simple and complex machines to explore the concepts of work and force. They discuss examples of simple machines they have found in...

An excellent activity awaits your young scientists! In it, learners are invited to explore the world of pulleys, levers, and planes; simple machines that make lifting heavy things much, much easier. They watch video, and engage in...

Young biologists identify parts of the body that serve as wedges (teeth and fingernails), and as levers (jaw, arms, and legs). The hands-on activities described here should be exciting for learners to perform, and should also lead to a...

Teach young engineers that all machines, no matter how complicated or complex, are made up of just six simple devices with this hands-on physical science instructional activity. Using the included templates, students first create...

Young scholars identify the various parts of the body that serve as wedges and levers, identifying the fulcrum for each body lever. They bite into carrots and apples to analyze how their jaws and teeth work, then complete three...

A very impressive lesson plan on the Wright brothers and their place in aviation history. Learners discover many fascinating facts about the Wright brothers and their trials and errors regarding flight. Best of all, they get to build a...
