A trebuchet is a catapult that uses a counterweight to supply the energy for throwing. They were used in the Middle Ages for attacking castle walls. In this project, you build your own model trebuchet and investigate how design changes...

Students explore methods employing simple machines likely used in ancient pyramid building, as well as common modern-day material transportation. They learn about the wheel and axle as a means to transport materials from rock quarry to...

In this structured inquiry, learners will investigate a catapult system. Having previously explored and identified the variables of the catapult system (length of lever, mass of shot, angle of catapult), students will conduct controlled...

In the following video Paul Andersen begins by discriminating between translation and rotational motion. He then explains how a torque is the product of the lever arm and the force perpendicular. [7:03]

In an open-ended design activity, students use everyday materials (milk cartons, water bottles, pencils, straws, candy) to build a small-scale transportation device. They incorporate the use of a wheel and axle, and lever into their...

Simple machines are devices with few or no moving parts that make work easier. Students are introduced to the six types of simple machines - the wedge, wheel and axle, lever, inclined plane, screw, and pulley - in the context of the...

Young scholars apply the mechanical advantages and problem-solving capabilities of six types of simple machines (wedge, wheel and axle, lever, inclined plane, screw, pulley) as they discuss modern structures in the spirit of the...

Watch a demonstration on how to put lever switches on a small robot. [10:24]

Explains how government can effect aggregate demand through tax policy.

More on mechanical advantage, levers and moments. [6:50]

In this lesson plan students start by trying to open a paint can with their bare hands. Eventually, they will use a lever to open it. Various activities are used to enforce different simple machines.

Learn how the equation for torque was derived through this video lesson. The lesson explains how to use geometry to find the lever arm and perpendicular component of the force. [6 min, 55 secs]

There are six simple machines. They are as follows: lever, wheel, pulley, incline plane, wedge, and screw. This tutorial will cover the first three.

Investigate how levers can be used to lift objects and discover how the position of the fulcrum affects the force and the distance of the load lifted.

Kids learn about the science behind simple machines such as levers, wheels, pulleys, inclined planes, and screws. How they work together to make complex machinery.

Read the story behind Archimedes' claim that he could lift the Earth with a lever. The author analyzes this hypothetical claim to show that it would never be possible to lift something as massive as the Earth.

In this Cyberchase video segment, the CyberSquad finds the right combination of switch, lever and button that will deactivate the force field protecting the stolen Black Crystal. [3:21]

This site describes different types of linkages and how they are used in simple machines.
