Students as Teachers: Research Links
Many of the links below are from University Sites. Some of the language used may be a little complex for some students, but the graphics are good. Remember, do not dwell on the chemistry and math involved with your topics (especially at the level of some of these sites!) Your task is to teach the general concept of your topic to your 8th grade peers!
Natural Selection Links
1. Full text of Darwin's Origin of Species
2. History of Natural Selection and examples
3. Early Theories of Evolution
4. Peppered Moth-Clasic example of Natural Selection (with JAVA model)
5. Excellent source on Natural Selection (a little "wordy" but good!)
Invasive Species Links
1. Good Background on Invasive Species
2. Invasive Species in Delaware
3. Some impacts of Invasive Species
4. Good Bulleted list of impacts
5. Good Basics and links
6. Profiles of Some Invasive Species-good source for examples
Succession Links
1. Frames Site with great graphics and explanations-focus on New Mexico though!
2. Slide Show-excellent sequence of text slides by Michael Collins, MUN
3. Very Good Basics! -Penn State
Nitrogen and Carbon Cycles
1. Biogeochemical Cycling: Inputs and Outputs of Nutrients to Ecosystems
2. Biogeochemical Cycles-Very Good!
3. BIOGEOCHEMICAL CYCLES 2
4. Introduction to Biogeochemical Cycles
5. Carbon Cycle Diagram
6. Matter Cycles in General
7. Legumes that Fix Nitrogen
8. Other Organisms that Fix Nitrogen
9. Outstanding Carbon Cycle Site!
10. Nitrogen Cycle
11. Really Good Nitrogen page (a little complex, but you can get it!
Natural Resources
Fossil Fuels: (oil, coal and Natural Gas)

1. Encyclopedia of Sustainable Development- Site from the UK but VERY good info on natural resources, fossil fuels, renewable impacts etc.

2. "Energy Matters" ThinkQuest project produced by high school students. VERY good resource on fuels and impacts. The science is well done and accurate.
3. "Natural Resources: Can We Use them Forever?" Good Source
4. Fossil Fuels and Population Good basics on fossil fuels
5. Uof D extension Service Good overview of renweable and non-renweable natural resources
6. "The Energy Story More on fossil Fuels and how they are formed.
Iron

Infoplease Basics of iron use and production

Encylopeadia Another good overview with outstanding description of iron use in steel making.
cleanerproduction.com Overview of production methods and source of pollution from iron production. Has a table of ways to produce iron cleaner
Aluminum

World Aluminum.com OUTSTANDING! (enough said!!)

Ask a Chemist Quick overview of how aluminum is made.
Aluminum Manufacturing Very technical and lots of word but covers TONS of info!
