(Main Idea: Ecological research methods include observation, experimentation, and modeling.)

 

 

Elephant Tracking

Article, video, and maps describing ecological research using GPS collars to monitor elephant movements

(Main Idea: Ecological research methods include observation, experimentation, and modeling.)

 

 

Examples of Abiotic Factors

Article describing several abiotic factors of the Great Salt Lake ecosystem

http://learn.genetics.utah.edu/content/gsl/physical_char/

(Main Idea: An ecological system includes both biotic and abiotic factors.)

 

 

Ecosystem Simulator

Simulation in which you can change one factor in an ecosystem and see the effect on other factors

http://www.learner.org/courses/envsci/interactives/ecology/ecology.html

(Main Idea: Changing one factor in an ecosystem can affect many other factors.)

 

 

Chemosynthesis

Video describing hydrothermal vent ecosystems and the chemosynthesizing producers that support them

http://www.montereyinstitute.org/noaa/lesson05.html

(Main Idea: Almost all producers obtain energy from sunlight.)

 

 

Food Webs

Interactive food web in which you can increase or decrease different species to see how the change affects the other members of the food web

http://www.eduweb.com/portfolio/earthsystems/food/foodweb4.html

(Main Idea: A food web shows a complex network of feeding relationships.)

 

 

 Hydrologic Cycle

Interactive diagram illustrating the cycling of water on Earth

http://earthguide.ucsd.edu/earthguide/diagrams/watercycle/

(Main Idea: Water cycles through the environment.)

 

 

Carbon Cycle

Interactive diagram illustrating the carbon cycle

http://www.sciencelearn.org.nz/Contexts/The-Ocean-in-Action/Sci-Media/Animations-and-Interactives/Carbon-cycle

(Main Idea: Elements essential for life also cycle through ecosystems.)

 

 

 Biomass Model

Interactive animations explaining why there are more organisms at the bottom of a food chain than at the top

(Main Idea: Other pyramid models illustrate an ecosystem’s biomass and distribution of organisms.)
