Working Principals of Gasoline Engine
Gasoline engines are used in every automobile and are the driving force for many electric generators and other industrial and household machines. Gas powered lawn mowers, chainsaws, blowers and trimmers are among the well known household and garden equipment. 

Have you ever wondered how gasoline produces power to drive a machine? Where does such a force come from? 

This project is an opportunity to learn about the structure and design of gasoline engines.

Material and instructions
In this project you will learn how a gasoline engine drives a wheel or other machines. You will also make models to demonstrate how a gasoline engine works. Materials for this project can be found at home or purchased locally. You may make a cardboard model or wooden model (described in the details section) to show how we can harness the pressure of burned gases to create rotational movement of a wheel. For older students who have the support of an adult, another experiment can be making a canon that works with the same principles of gasoline engines.
