Project UNIT 6: "MACHINES"

This is our last project. It is going to be very short an easy.
You have to set in pairs or groups of 3 people.
Here are the contents:
SIMPLE MACHINES
-Inclined plane
-Pulley
-Lever: class 1, class 2, class 3.
MACHINES
-Energy: what is it?
-Energy sources
-The function of machines

What you have to do is search one example of each in real life and bring a picture or drawing (you can bring it printed or in a pen drive).

You have to share all the contents, but it is important each pupil in the group says at least one of:
Classes of lever
Energy sources
The function of machines

OPTIONAL:
At home, you can build an example of an inclined plane, pulley or lever, or you can build all of them.
This isn´t compulsory, so if you don´t do it, it doesn´t matter.

Enjoy the project!!
