How large can a population become? The fifth installment of a nine-part unit teaches young ecologists about limiting factors that determine the carrying capacity of species in the Sonoran Desert. Here is a PowerPoint to help present this...

Ecology aces examine sea surface temperature maps and relate temperatures to concentration in fish and zooplankton populations. Take your class to a computer lab and provide experience with actual remote sensing data. Some of the links...

Students explore wolves. In this ecology and wolves lesson, students research predator-prey relationships on the Internet and complete a related worksheet with a partner. Students interpret data on bar graphs to determine growth and...

Sixth graders are introduced to online research and beginning PowerPoint presentations that are integrated. They pass a plant and photosynthesis. Students locate information on a self selected animal online. They give a PowerPoint...

Young scholars explore global water contamination and water shortage problems. In this geography/ecology instructional activity, students gain information about the lack of safe drinking water in many countries. Young scholars read, use...

Great things come in small packages! What better way to illustrate this point than a week-long look at nanotechnology? Earth science scholars explore water quality issues through lab activities, then research new innovations in nanotech...

Ninth graders conduct an environmental inventory on one ecosystem. They collect data, and write an environmental impact statement on that area. Students explain the interactions between different systems found within an ecosystem....

Second in a series of five lessons, this lesson encourages preteens to consider cities as urban ecosystems. First, they keep a food diary for a few days. They visit the Natrional Agricultural Statistics Service website for current data...
