Predator and Prey Game
Young scholars explore the why the balance among producers, predators and prey is necessary in order for an ecosystem to be sustained over time. Through web games and activities, they discover how each component of the food chain works...

Eyes on Dissolved Oxygen
Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect...

Life in a Forest Stream
Students assess macro-invertebrates from a stream. In this science lesson plan, students observe, classify and identify organisms found in a stream. A lab station is constructed at the stream sight and students study the different...
Curated OER
The Portable Niche
Third graders, in groups, research animals, plants, and conditions found in ecosystems.
Curated OER
Extensions - Biology Review Unit
Students engage in a variety of activities in order to review a Biology unit. For example, they research the Bird Flu, it's history, how it is spread, what has been done about it, what better options exist for controlling or removing it....
Curated OER
Selecting Soil Organisms in Compost
Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...

Selecting Soil Organisms in Compost
Pupils demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment in...
Curated OER
Consider the Issues
Students develop and express opinions on personal and societal issues in biology through journal entries (written and other forms), oral position statements and group discussions.
