Human Impacts on Alberta River Ecosystems is a Grade 8 Science worksheet focused on the Interactions and Ecosystems topic and the ways human land use can affect river ecosystems and watersheds. Students examine how changes to habitat structure, water movement, wetlands, nutrient cycles, and species can alter ecosystem interactions.

🌿 Apply Ecosystem Concepts to a River System

The resource moves beyond simple recall by asking students to apply ecological concepts to a realistic resource-use scenario. Students describe how human land use changes habitat structure and ecosystem interactions, explain how water diversion and wetland drainage can affect nutrient cycles and species, and identify evidence of cumulative effects within a watershed. They also consider mitigation actions that could reduce human impacts.

📝 Varied Practice and Assessment

Students work through a purposeful mix of multiple-choice questions, true/false statements, short-answer questions, a reading passage, matching, a cloze passage, an essay response, and a Did You Know section. This combination provides opportunities to recall concepts, interpret information, apply ecological reasoning, and communicate ideas about human impacts on river ecosystems.
