- Easier - A simple
machine is a device that helps make work easier; a
device that makes it easier to move something. Some
simple machines are a wheel, a pulley, a lever, a
screw, and an inclined plane.
- Harder - Most
machines consist of a number of elements, such as
gears and ball bearings, that work together in a
complex way. No matter how complex a machine, it is
still based on the compounding of six types of simple
machines. The six types of machines are the lever, the
wheel and axle, the pulley, the inclined plane, the
wedge, and the screw.

- Learn about devices that make work easier to do by
providing some tradeoff between the force applied and
the distance over which the force is applied. Also
provides a brief introduction to uses of a gear, cam,
crank and rod, chain and belt, and the ratchet.
from Beakman & Jax
- Play with levers and find out how work from the
fulcrum to the load to the effort.
- (Wait for second page to come)
- This website provides a series of experiments
about simple machines: levers, wheels and inclined
planes. They were developed for third grade students.

- Learn about four simple machines ( Inclined
planes, pulley systems, levers, and the wheel and
axle). All are mechanisms that convert energy to a
more useful form.

Energy and Simple Machines by J.S.
- This site investigates Newton's Laws of Motion and
the concepts of potential and kinetic energy. The
concepts of force, friction, energy transfer, and
mechanical advantage are explored as you build simple
machines and investigate there operation.
No Lego® Wedgies! from Weird
- Explore the wedge, the active twin of the inclined
plane. It does useful work by moving. In contrast, the
inclined plane always remains stationary.
