Ecology and the St. Lawrence River
Ninth graders complete a unit of lessons on ecosystems, organism interactions, and energy flow. They create a key for known species of fish, diagram the movement of energy through an ecosystem, and create and present food chains and food...
Curated OER
Studying a Piece of an Ecosystem
Students carry out an outdoor land study in which they identify organisms living in the soil, and any other animals living within the site. Groups also examine abiotic factors. They respond to a series of questions concerning their data...
