1. In depth, describe how a pneumatic motor
works exactly.
2. What or how would the earth react after so many years of cars running on compressed
3. Does a pneumatic motorized car run differently in comparison to a common hydraulic motor?
4. How does a Pneumatic engine relate to the Particle Theory?
Purpose:
To determine how the earths environment will be affected after the end result of years and years of cars running off compressed air.
Hypothesis:
We believe the earth will be greatly affected by cars running off compressed air because it will help the earth by less pollution and it will help gas last longer than it would if all cars ran off gas.
Materials:
To make a pneumatic engine for a "air compressed engine car" you need:
a valve, pressure gauge, a pump, and conductors.
Variables: Control variable: Engine Independent variable: Gas/air (Pneumatic) and Fluid (Hydraulic)
Procedure:
1. After completion of the pneumatic engine, add gauge to determine the type of air being emitted. Complete this on both the hydraulic engine and pneumatic
2,. Let engine run on with pressure gauge on both for 10 minutes. observe gauge in the meantime.
3. Measure the difference from observations. you should than be able to determine which engine is more beneficial to the environment.

How does car pollution affect the environment and ozone layer?
The U.S Environment Protection Agency states that more than half of the air pollution in the nation is created by mobile sources, mainly automobiles. Vehicles contain many different fluids that are toxic to humans and animals such as motor oil, anti-freeze, gasoline, air-conditioning, refrigerants, and break, transmission, hydraulic and wind shield-wiper fluids. Theses fluids can pollute water ways if they were to leak from a vehicle of, or are disposed of incorrectly. The earths ozone layer is there to help protect life on earth from the suns ultraviolet rays, but human activities have contributed to help destroy this protective shield. The substances that have contributed to ozone depletion usually have high chlorine or bromine atoms concentrations, and include chlorofluorocarbons, of CFC's halons, methyl, bromide, carbon tetrachloride, and methyl chloroform.
Pneumatic engines, pros and cons.
Pros
Cons

In depth describe how a Pneumatic motor works exactly.
For one, a pneumatic motor is a motor that runs on compressed air. It consists of valves, a pump (which includes pistons, and cylinders.), conductors(providing a pathway for the compressed air), a pressure gauge(to determine the air pressure and the amount of air exiting the engine), and an engine. Now to describe how it all works. The more affordable way of refilling, is a start to the way a Pneumatic motor works. The air is filled in through the air tank waiting to be compressed through the tube. Once it is time, it the compressor stream and is held in the air cooler, It is then brought to the engine to provide power for the car to move or accelerate. After finishing the engine process, it is brought the the next compressed air tube to be let out into the soon-to-be clean earth. The pressure gauge then monitors the pressure being exiled. The process is complete and then ready to be continued.
We have chose to utilize the important titles Pneumatic and Hydraulic into our "Create your own Scientific Investigation" project. These briefly covered topics were only a beginning to our acquired interest. As partners we consulted through the large variety of different scientific topics we have covered greatly. We finalized our consultation to being strictly about the long term affect on the environment by using Pneumatic engines (compressed air engine) or using Hydraulic engine. Which would be more beneficial to our earth as we progress in our life. it has in fact been stated that the detrimental gas emitted from commuting to work, driving your kids to school, or even to run errands is slowly affecting global warming, our protective ozone layer, and many people as well. The year of 2010, 223 000 people were affected with lung cancer and passed away, worldwide because of air pollution. We wanted to greatly recognize the benefit of automobiles running on Pneumatic engines. Pneumatic engines are sections of technology that deals with the study and application of compressed air to produce mechanical motion. Prototypes of these air cars have been designed and created but have yet to pursue its fame. We have considered the fact that pneumatic engines have lack of space in their tank, but we are sure through the great technological advances our earth has been going through this bend in the road will be the least of our worries due tot the environmental issues. All in all as you listen to our presentation you will gain more of a scientific understanding. Overall after overlooking our experiment, we did in fact discover bias in our research. Where we found bias was when they stared talking about how pneumatic engines are in fact not good to use, and hydraulic are better and more efficient, only because pneumatic engines cannot hold a heavy load. Even though they make pneumatic engines sound worse, there are also the down sides to hydraulic engines like, how if the hydraulic fluid is disposed of improperly, it could be an environmental risk, Mishandling and constant exposure to a hydraulic fluid, and its gas fumes without proper precautions and equipment is a health risk, and more. Some of the bad things about pneumatic engines are that in the long term, it is more expensive, because its running off basically air its less efficient because tests have shown that there is a limited amount of space in the tanks that hold the compressed air, and more.

What or how would the earth react after so many years of running on pneumatic engine or compressed air?
After years and years of cars running off compressed air, the earth would react in a very good way because right now, the cars that run off gas are effecting the environment in many horrible ways, some in which include air pollution, damage to environment, the toxic elements coming from the gas in the cars harming humans and animals, damaging the ozone layer, and many more. If we started promoting air compressed eninges in cars, we would be doing a very great thing in helping our own environment that we are still continuously destroying by doing the daily activities that we do today.
What is the difference between a Pneumatic motor and a Hydraulic motor?
Pneumatic and Hydraulic are both similar because they are applications of Fluid power. Their differences vary, one including pneumatic uses compressible are or a pure gas, as hydraulic uses a liquid known as oil. Pneumatic= 80-100lbs/si and Hydraulic=1000-5000lbs/si. Pneumatic systems are very reliable and easily designed. The chance of a pneumatic motor catching fire is low in comparison to Hydraulic, running on oil. The Hydraulics uses a gas which doesn't absorb supplied energy. Hydraulics have much more capability of moving heavier loads which is a big downside for pneumatics.

How does a pneumatic engine relate to the particle theory?
A pneumatic engine relates to the particle theory because....
- When the temperature/pressure is increased,the energy level is increased as well
- Particles have spaces between them, but when pressurized they will try to spread out
- The gas particles are always in motion
Evaluation of research and changes we could make.
In further thought at the end of this project there are things believe we could have changed some including. Trying to meet our deadlines. Expanding in research. Looking in to How much pollution is actually being exiled through the use of a Hydraulic motor. And last but not least meeting up more to go over the project more in depth to gain more of an understanding. To support these changes, to meet our deadlines I believe we could have planned more reasonable ones for us, considering the amount of work we still had outside of class. To look into the amount of pollution actually being exiled we could have simply expanded the research portion and look in with more depth. and lastly getting together to go over the project to gain more of an understanding could have been achieved my using the given calender to more successfully mark places on it as to when to meet at eachothers houses, instead we just planned one day on short notice to do a large chink of the project on.
Our note-taking strategy
Split- page note making
Affects the environment.

several detrimental gases are being emitted to this earth when a car is running. Such as: carbon dioxide, hydro-carbons, greenhouse gases, etc.
air quality has improved since the mid 70's because the clean air act took place, it almost faded out gasoline
carbon dioxide contributes global warming
air pollutants have exerted from cars releasing into our soil and the surface of lake water and such eventually connecting to our food chains
can effect reproductive, immune, respiratory, and neurological systems of animals
contribution to acid rain also takes place through gas emitting
vehicles contain fluids such as motor oil, anti-freeze, gasoline, wind-shield wiper fluids, etc.
Hydraulics and Pneumatics.
Pneumatic: a system that uses pressurized air or other gases to do work
Hydraulic: a system that use liquids under pressure to perform a specific function
Consists of: a pump(including cylinders and pistons), conductors(providing a pathway for the independent variable), valves(keep component moving in desired direction), a pressure gauge(monitors pressure exiled from system)
Pneumatic=80-100lbs/psi
Hydraulic=1000-5000lbs/psi
Pneumatic system is reliable and easy designed
low chance pf fire caution
Hydraulic systems have a big caution due to it running on oil
