SIMPLY HELPFUL
Simple machines make our lives easier. They help us by transferring a load, changing the direction of a force, and making things easier to lift. They are part of our everyday lives. Examples include screwdrivers, door handles, a wheel and axle in a car, or a ramp that helps people get in and out of buildings.

Can you name an object that sinks in water but also floats? A submarine, of course! A submarineâs ability to both sink and float has to do with density and buoyancy. See if you can build a boat that seems to defy the laws of buoyancy.
