Define what a Simple Machine is.
A device that makes work easier by changing the direction or magnitude of a force.
A machine that uses electricity to operate.
A tool that only works underwater.
A device that creates energy from nothing.
How do Simple Machines make work easier?
By increasing the amount of work needed.

Inclined Plane
Wedge
Pulley
Screw
Imagine you need to move a large log across the ground. Which combination of simple machines from the list could you use to make this task easier, and why?
Lever and Wheel & Axle, because the lever can lift the log and the wheel & axle can help roll it.
Wedge and Screw, because the wedge can split the log and the screw can hold it together.
Pulley and Inclined Plane, because the pulley can lift the log vertically and the inclined plane can slide it down.
Pulley and Wedge, because the pulley can move the log and the wedge can cut it.
