Greenhouse gas simulation


Click on the above image and run the simulation. Note what happens to temperature at different levels of greenhouse gas in the atmosphere. Compare levels of greenhouse gas from the 1700s, the ice age, and today. After you record that temperature data you can manipulate the level of greenhouse gas and see what happens. The yellow photos are light that are coming to the Earth from the Sun and the red are infrared photos also known as heat.

Biofuels


We have our own biofuel vehicle that students at NGHS created. Go to the Fat to Fuel blog to check it out http://ngwvovehicle.blogspot.com/

Energy Sources Research


Use the following links as well as others you find on your own to learn about energy and sources of energy we use. 

Cool interactive site made by students for students. This won a competition for student created websites: http://library.thinkquest.org/06aug/01885/ 


Energy Quest’s Energy Story site is at http://energyquest.ca.gov/story/index.html Chapter 6-20 are good resources.


The butons on the left side show many different types of energy resources including fossil fuels, nuclear, solar, wind, tidal, hydroelectric, wave, geothermal and biofuels.

ThinkQuest.org has an Energy Matters site at http://library.thinkquest.org/20331/types/
It covers fossil fuels, renewable fuels and nuclear fuels.

If you were absent, please use the above links or and other websites to answer the following questions. If you find a really great link, please send it to me as a comment to this post for extra credit (be sure to include your first name and last initial so I know to whom to give the credit.)

Use the sites for research, but please write your answers in your own words.
 
1. What is energy?

2. What is the difference between chemical, potential and kinetic energy?

3. What is a “non-renewable” resource? Define it and give 3 examples.

4. What is a “renewable” resource? Define it and give 3 examples. 

5. Explain do you think we still use mostly non-renewable resources? Is this good or bad? Why?


6.  Describe advantages and disadvantages of the following:

Energy Source
Advantages
Disadvantages

7. What 4 types of energy sources do you think will be used most in the future? Why?
