Background Information:
A simple machine is something that makes work easier. Simple machines make lifting, pulling, pushing, joining and splitting easier. In grade two, we are learning about:
*Wedge -has a pointed end, like the tip of a nail. This is used to split things in two (like an axe), or prop thins open (like a door stop)
*Lever – a bar that is straight or bent, pushing down on one end makes the other move up, like a see-saw. Levers can help us move heavy objects. Examples are brooms, shovels. Examples of double levers are scissors or pliers.
*Pulley – a pulley is a grooved wheel with a rope around it. Pulleys help us raise or lower a load. Examples are a clothesline, and a flagpole.
*Wheel and axle – a wheel that turns around a stick or bar can be used to help carry things. Examples are skateboards, and bicycles.
*Inclined plane – a ramp that lets us raise heavy things without lifting them straight up. Ramps and stairs are an example.
*Screw – is used to hold things together. This is a type of inclined plane. Examples include screw, and lids on jars (with threading).
Task:
Each student is to create a machine that does work to make a job easier. The machine needs to be a combination of at least 2 simple machines from the list above. Students need to be able to describe what the machine does, and how it works. Examples might include a pet food dispenser or a cart to carry items from place to place in the house.
Happy creating!
