Here are pictures and what the pictures do. By: Aaron and Jenna

Simple machine
What does it help you do? How does it help?
Picture, resource, video, etc.
It makes things lighter and you can hold more

wheel and axle
As you can see it has wheels on the bottom and the axel pulls it.

It pulls heavy things that helps us when something is heavy and we need help carring it to the top floor those help us.

E xample
a force is a push or pull
If you push or pull anything it repesence a force.
what is done when a force moves soemthing
If you push or pull something and it moves than that is work if it doesn't move than it is not work.
the effort is a forse needed to move soemthing
People use effort to help move something.
Mechanical Advantage
This is a measure of how much effort you save by using a machine.
If I push a box up a 16 foot inclined plane to get onto a 4 ft shelf,
I need to divide 16/4=4. The mechanical advantage is 4. That means it is 4 times easier to lift the box using the incline plane.
A force (such as gravity or fraction) that slows down or stops movement
if something is moveing and your pulling it the other way, your the ressistance.

Teacher Comments
The definitions are very good.
The examples make a lot of sense.

Example of how it helps you
A pulley makes things feel lighter, but it doesn’t actually make them lighter. A wheel and axle makes it easier to push or pull things. Some levers can open doors. You don’t really explain how a lever helps. The explanation for the screw is a good one.

Picture or resource
All the pictures are good examples.
