Grades 3-5. Designed to enhance the teaching of the Science and Technology Concepts Program™ in the classroom, the STC™ Ecosystems Student Investigations eBook allows students and teachers 24/7 access to their STC—Elementary™ content. In the Ecosystems unit, students set up terrariums for crickets and isopods. Duckweed, algae, Elodea, guppies, and snails are introduced to an aquarium. Connecting the 2 habitats to create an "ecocolumn," students observe the relationship between the 2 environments and the organisms living within them. Students simulate the effects of pollutants (road salt, fertilizer, and acid rain) on the environment. To discover how pollutants might affect the organisms in their ecocolumn, students create a food chain and make inferences about the effects of pollutants based on the relationships between the organisms in their ecocolumns. Students explore the Chesapeake Bay as a model ecosystem, analyzing the environmental problems present there from various perspectives. Applying their knowledge of ecosystems to a real-world situation, students generate possible solutions to the pollution problem and share their conclusions with the class. Access for 30 students per year for 60 months.
