The Greenhouse Effect

Objectives/Goals 

My objective is to determine the effect of different gases on the greenhouse effect. I am doing this project because of the strong interest in the effect of gases like CO(2) and CH(4) on global temperature.

Methods/Materials

Materials:

1. Infrared test cell made up of PVC pipe containing a black-body absorber/radiator and closed off with polyethylene film. (Polyethylene was chosen because it is relatively transparent to IR.)

2. IR source (heat lamp)

3.Thermocouple for measuring temperature

4. CO(2) gas

5. Air

Procedure:

  1. Purge test cell with air.
  2. Shine IR source into the cell for a fixed amount of time
  3. Measure temperature rise over time
  4. Purge test cell with CO(2)
  5. Shine IR source into the cell for the same amount of time
  6. Measure temperature rise over time


Results 

The temperature rise in the cell when filled with CO(2) was slightly higher than when the test cell was filled with air. 

Conclusions/Discussion 

After many test runs I determined that there is a greater temperature rise when the test cell is filled with CO(2). That supports the hypothesis that CO(2) enhances the greenhouse effect. 

On the other hand, the additional temperature rise in a 100% CO(2) atmosphere is not substantially greater than with ordinary air so it is entirely possible that small increases in CO(2) might have only a small effect on temperature rise in the Earth's atmosphere.

Make a Rocket

Rockets are fascinating!  They soar into the sky and help us know many secrets. Are you fascinated by rockets? If your answer is yes, you would be interested in this activity. The rockets that you can make safely will not go very far, perhaps much less then the rockets we enjoy on the Deepawali day. But then you will agree, the fun and excitement to make your own rocket has a totally different dimension.  The basic principle of rocketry is Newton's Third Law of Motion, that is, "For every action there is an equal an opposite reaction".  A big rocket uses chemicals to release an intense stream of gas out its tail end that propels it upwards.  A fuel is used in a rocket to produce this gas through some chemical reaction. The rocket fuel is sometimes liquid, and sometimes solid.  But, in all cases, a gas is ejected from the tail of the rocket. The first kind of rocket that we can make is propelled by a very safe gas - carbon dioxide.  The ...

Make a Periscope

Are you familiar with the word "submarine"? A submarine is a kind of boat that moves underwater. Submarines are common crafts for the Naval forces of any country. But, while moving underwater, submarines need to know where they are with respect to other objects on the surface of water. The device they use to do this is called a periscope.  Periscopes are optical instruments that can afford submariners a limited though vital visual picture outside their windowless hull. Traditionally, periscopes offered the submerged submarine its only glimpse of the outside world. Classic English war movies have also made them the submarine's most familiar feature.  For most of us, who are unlikely to come across submarines in real life, a periscope can make it possible to see round corners and over the heads of crowds during processions or at sporting occasions. In a periscope, two mirrors are arranged at 45 degrees to each other. One mirror captures the rays of light from t...
