Global Symposium
Ninth graders work together to develop a sysnopis on the Earth. Using the Internet and print sources, they focus on one country to research and determine its condition. They offer possible solutions to the problem and share their...

Nuts & Bolts: is Classification, Arbitrary, Or Not?
Students, in groups, classify furniture, share their categories and rationales, then note how their different schemes vary, perfectly logical and useful, but completely arbitrary.

An Investigation into Effects of Rhizobium Soil Bacteria on Nitrogen Availability
Students identify the control and the variables in the experiment. They describe the growth of plants with and without nitrogen fixing bacteria, then name the bacterium responsible for making nitrogen available to the plant.

Aquatic Insects: Water Quality Index & Diversity Index
Students search stream beds to study the life cycle and adaptations of stream insects. They explore creeks and streams to see the diversity index of creeks or streams and to find the water qualit index.
Curated OER
Biotic Factors
Students identify individual organism, a species, and a population within the study community. They identify biotic factors at the site and attempt to characterize the site's species diversity.
Curated OER
Educating the Community
Students research the effects of invasive and exotic plants. They create posters, webpages and books to educate the community. They present their material in different forums.

Lotic Environment Lesson Plans
Learners create and conduct experiments on a "classroom river habitat." They manipulate the biotic and abiotic factors so that they are able to compare an artificially prepared river model to a naturally occurring lotic ecosystem.

Field Experiments on Succession
Student develop a hypothesis regarding the effects of either mowing or fertilizer upon the diversity of plant species in a grassland ecosystem. They set up experiment field plots and measure species richness.

Serc: Investigating Observing Stabilizing and Directional Selection
In this biology lab learners will compare two sample populations of sunflower seeds. Comparison of the two populations will be done through the generation of a histogram for each population. One population will be black oil sunflower...
