An in-depth explanation of the wheel and axle from Scholastic. Also provides several examples and a picture for understanding.

Describes some history of the wheel and axle, how it works, the formula for calculating its mechanical advantage, and some applications of the wheel and axle.

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...

A lab investigation of an accelerating object can be difficult without motion sensors or computer photogates. The accelerating object can gain velocity in such a way that it moves a great distance in a short time.

This lesson plan introduces students to three of the six simple machines used by many engineers: the lever, the pulley, and the wheel-and-axle. In general, engineers use the lever to magnify the force applied to an object, the pulley to...

Learn how wheels and axles help with force and motion.

This lesson will explain how to calculate the mechanical advantage of a wheel and axel. It is 1 of 2 in the series titled "Simple Machines: Wheel and Axel."

This lesson will explain how to calculate the mechanical advantage of a wheel and axel. It is 2 of 2 in the series titled "Simple Machines: Wheel and Axel."

Several good activities here. Look particularly at Wheel Figure It Out (which is the opening page) and Gearing Up. There are answers to the very good questions at the bottom of each.

A solid chapter explanation of the wheel & axle simple machine. Examples, the basic math, explanation of mechanical advantage, drawings, solved problem. Use the Next button. There are four pages in this chapter.

In this activity, students reinforce their understanding of compound machines by building a catapult. This compound machine consists of a lever and a wheel-and-axel. Catapults have been designed by engineers for a variety of purposes -...

An encyclopedia article from Wikipedia on the wheel discusses how wheels operate and travel on surfaces, and gives information on the invention and use of the wheel in ancient times. Links are also provided for additional information.

Learners 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 engineers and...

A slideshow and a short quiz on simple machines and how they reduce the amount of work or effort needed to complete a task.

Simple machines are devices with few or no moving parts that make work easier, and which people have used to provide mechanical advantage for thousands of years. Students learn about the wedge, wheel and axle, lever, inclined plane,...

Through a five-lesson series with five hands-on activities, students are introduced to six simple machines - inclined plane, wedge, screw, lever, pulley, wheel-and-axle - as well as compound machines, which are combinations of two or...

Refreshed with an understanding of the six simple machines; screw, wedge, pully, incline plane, wheel and axle, and lever, student groups receive materials and an allotted amount of time to act as mechanical engineers to design and...

Simple machines are everywhere, even many of your toys are simple machines. Come visit this science fair project and explore the six types of simple machines. Find out how many are hiding under the hinged lid (yes, another simple...

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...

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...

A thorough discussion of all the simple machines, beginning with some thoughts on mechanical advantage and conservation of energy. Very complete. Move down to the section that interests you.

Identify the six simple machines by dragging the correct term, and dropping it onto the associated simple machine.

In this problem solving exercise, students must decide which simple machine would work best in different situations, in order to help the principal manoeuvre himself after he has hurt his leg and can't walk. The site has a good tutorial...

Provides definitions of all 6 simple machines with examples and student drawing of them. Interactive "simple machines quiz" at the end.
