When we think of machines, the likes of robots, appliances and manufacturing equipment come to mind, but scientists also classify such common objects as the screw, the lever, the wedge and the wheel ...

Find out how simple machines makes work easier on this Science Trek. Simple machines include the lever, the inclined plane, the wedge, the pulley, the wheel and axle, and the screw. Combine these and ...

Introduction: This lesson provides students with a review of simple machines and their tasks. It works best in combination with your lesson on simple machines, or as a review/additional activity.

Can you make a screw out of a piece of paper and pencil? Your friends might think it is magic, but it’s science at work. Here’s an easy experiment that might add a “twist” to your thinking. MATERIALS ...

Explains how pulleys work to lift heavy weights more easily. A fixed pulley changes the direction of force, allowing for easier lifting, while a movable pulley reduces the amount of force needed to ...

Throughout history, humans have developed several simple machines to make work easier. The most notable of these are known as the "six simple machines": the wheel and axle, the lever, the inclined ...

WAAAAAYYY back when I was in middle school physics they had some programs on our school computer that let you build simple machines. We basically built Rube Goldberg machines in the simulator to test ...

Physicists have devised an algorithm that provides a mathematical framework for how learning works in lattices called mechanical neural networks. It's easy to think that machine learning is a ...

Simple machines make work easier to do. But how? Join Joan at the Discovery Center of Idaho as she tries various experiments with simple machines. Science Trek is available to stream on pbs.org and ...
