Global Warming and the Greenhouse Effect

Extracts from this document...

Introduction

Austin Richardson Davis - 3 09/31/00 Honors Chemistry Global Warming and the Greenhouse Effect In the science fair project, which I am going to be performing, has to do with global warming and the greenhouse effect. The definition of global warming is increase in the earth's temperature caused primarily by increased emissions of several gases into the atmosphere particularly carbon dioxide (CO2), methane (CH4), and nitrous oxide (N20), ozone (O3), water vapor (H20). When these gases are trapping heat, they cause greenhouse effect. The definition of greenhouse effect is the role the atmosphere plays in insulating and warming the earth's surface. The problem that I have run into during study is to know is global warming will affect the world greatly on the environment or is it nothing to worry about. ...read more.

These will both be affected by the independent variables which are time and weather. No one has control over time and weather, that is why they are the independent variables and they also affect the outcome of the experiment. The atmosphere is not transparent, that is why the earth warms up. Since there are not as many trees and things to absorb the carbon dioxide, the temperature rises and humidity also rises. Procedure: 1. First, collect the materials that you will need for the experiment. These include the following: 2 two liter plastic soda bottles (washed out cleanly), scissors or box cutters, two long thermometers, Three strips of cardboard (1/2" x 1"), soil, sand, water (in spray bottle), plastic wrap, rubber bands (medium size), ...read more.

Conclusion

The other bottle will be left open and will be the control bottle. 7. Position the lamp approximately 20 to 30 centimeters above the bottles. 8. Record the beginning temperature for each bottle. 9. Turn the lamp on. 10. Record the temperature every minute for 15 minutes. 11. After you are finished recording the temperature, fraph your data by plotting the temperature on vertical axis and time on the horizontal axis. One colored pencil can be used to graph the experimental reading as a solid line and the control reading as a dotted line. Also, the use of the CBL and graphing calculator can be used to measure temperature. After following the procedure and drawing a graph, you should come to your conclusion about global warming and the greenhouse effect. ...read more.

    CO2 Fertilization Because plants require CO2, rising levels may actually help plant growth. However, the increased plant growth requires adequate water supply and other fertilization, such as nitrates. Experiments in which crops are grown in CO2-rich air show that the CO2 fertilization effect could become small after a few years.

    NITROUS OXIDE Nitrous oxide is another colourless greenhouse gas but unlike the others has a sweetish odour. It is used as an anaesthetic because it deadens pain and is also known as laughing gas. It's released naturally from oceans and bacteria in soil, used for cars with catalytic covers, used in nylon and in the burning of organic matter.

    I believe global warming is a big threat to our nation and the world. If we do not act now, it may be too late. Although there is no sure way of telling what the climate will be like in the future we must take steps to ensure the health of the Earth.

    But many scientists think it could be at least partly due to the increased burning of fossil fuels. They suggest that if fossil fuel burning continues to increase at the current rate, carbon dioxide levels could rise rapidly. Another suggested cause of the rise is deforestation.
