Ecological interactions in Alberta ecosystems become the focus of evidence-based investigation in this Grade 12 Science 30 learning stations activity. Through documented ecological case studies, students examine how species relationships, population changes, environmental conditions, and human activities influence ecosystem stability.

Ecosystems in Action: Alberta Ecological Interactions moves beyond identifying ecological relationships. Students compare environmental changes, investigate their consequences, and evaluate management strategies using scientific evidence and ecological principles. The station format encourages students to connect individual ecological events with broader patterns in ecosystem functioning.

Explore Ecosystems Through Real-World Cases

Ecological stability depends on interactions among organisms and their environments. Changes in one part of an ecosystem can affect other species, disrupt ecological processes, and influence the benefits ecosystems provide.

This Alberta ecology activity focuses on several connected scientific concepts:

• Species interactions: Analyze how relationships among organisms influence ecological communities.
• Population dynamics: Examine how changes in population size and environmental conditions affect ecosystem stability.
• Food webs: Explain how human activities can alter feeding relationships and ecological connections.
• Habitat changes: Investigate how environmental disturbances affect organisms and their surroundings.
• Nutrient cycling: Consider how human influences can disrupt the movement of nutrients through ecosystems.
• Ecosystem services: Examine how ecological changes affect the benefits provided by natural systems.
• Environmental management: Compare ecological changes and evaluate management responses using evidence.

What's Included in the Resource?

The materials are organized around a learning stations structure that supports investigation, written recording, and discussion.

• Station case-study cards: Reading materials for investigating documented ecological examples.
• Station recording sheet: A student worksheet for organizing information and observations from the stations.
• Station wrap-up: A concluding activity for bringing together ideas from the investigations.
• Teacher Guide: Included in the Answer Key PDF, with learning objectives, teaching tips, discussion questions, and common mistakes.

How to Use the Learning Stations

Place the ecological case-study cards at different locations around the classroom. Students work individually or in small groups to examine each case and record relevant information on their recording sheets. Groups then rotate through the stations to investigate additional examples.

After the rotations, use the station wrap-up to help students synthesize their findings. The Teacher Guide provides discussion questions to support a class conversation about ecological change, human impacts, and the evidence behind environmental management decisions.

This structure works well for a focused ecosystem investigation, a Science 30 ecology review, or a classroom activity that connects ecological principles with documented environmental examples.

Why This Approach Matters

Ecological problems rarely involve a single isolated factor. A population change may influence species relationships, while habitat alteration can affect food webs, nutrient cycling, and ecosystem services simultaneously.

By examining documented cases rather than considering concepts only in isolation, students practice explaining these connections and making evidence-based comparisons. The recording sheet provides a consistent place to organize findings, while the wrap-up encourages students to develop conclusions across different examples.

Bring ecological interactions, human environmental impacts, and ecosystem management together in one structured Grade 12 science investigation.
