Human impacts on forests become concrete in this Grade 6 Science learning stations activity focused on Alberta forest and freshwater ecosystems. Students examine documented cases and record evidence about how human activities can alter habitats, water quality, species composition, and connected ecosystems.

Explore Human Impacts Through Case Studies

Rather than treating environmental change as a single type of problem, the station format asks students to consider different forms of human activity. They identify impacts associated with land use, resource extraction, pollution, and introduced species, then connect those activities to changes in forest and freshwater habitats.

The recording work also develops an important comparison skill: distinguishing immediate effects from changes that continue across broader areas or longer periods. This gives students practice thinking about both direct impacts and cumulative environmental change.

What Students Do

• Rotate through case-study station cards focused on human impacts.
• Record key information from each case on a station recording sheet.
• Identify ways human activities change forest and freshwater ecosystems.
• Explain effects of land use, resource extraction, pollution, and introduced species on habitats.
• Compare immediate impacts with longer-term or larger-area changes.
• Complete a station wrap-up that brings the cases together.

Included Teacher Support

The resource includes the station recording sheet, station wrap-up, station cards, and teacher guidance. The Teacher Guide is included in the Answer Key PDF and provides learning objectives, teaching tips, discussion questions, and common mistakes to support preparation and follow-up discussion.

Built for Collaborative Science Learning

Use these Grade 6 science learning stations for small-group rotations during a Trees and Forests lesson. Groups can move from case to case, record their observations independently, and then compare findings as a class. The structure also supports discussion about why an environmental effect may extend beyond the place or moment where a human activity first occurs.

The Alberta framework and focus on forests and freshwater ecosystems make this activity especially useful when teaching environmental impacts within a Trees and Forests unit. Students work with specific ecological ideas while practicing identification, explanation, and comparison rather than simply recalling definitions.

Why This Resource Earns Its Place in the Unit

This activity connects human impacts on ecosystems with the reasoning students need to explain environmental change. By moving among cases, students encounter multiple causes and consequences and can compare patterns across examples. The accompanying teacher guidance helps turn the station work into a structured whole-class conversation about habitat change and cumulative effects.
