Alberta Trees and Forests learning stations give Grade 6 Science students a structured way to classify organisms and examine how those classifications connect to ecosystem change. Students work with ecological roles and species status while considering how organisms influence energy flow, competition, decomposition, and ecosystem balance in Alberta.

Classification With an Ecosystem Purpose

Rather than treating classification as isolated vocabulary, this activity connects categories to what organisms actually do within ecosystems. Students distinguish ecological roles such as producers, consumers, and decomposers and classify species as native, introduced, invasive, or pests. They then use those classifications to think about relationships and changes within Alberta ecosystems.

The station format supports comparison across cases. As students move through the station cards, they record information on their own station recording sheet and bring their observations together in the station wrap-up. This structure encourages students to connect individual examples to broader ideas about ecosystem balance and management.

What Students Practice

• Classifying organisms according to their ecological roles
• Distinguishing native, introduced, invasive, and pest species
• Explaining effects on energy flow and decomposition
• Examining competition and changes in ecosystem balance
• Comparing how species classifications support understanding and management of Alberta ecosystems

What You Receive

• ✅ Station cards for the learning-stations activity
• ✅ Student station recording sheet
• ✅ Station wrap-up activity
• ✅ Teacher Guide included in the Answer Key PDF

The Teacher Guide adds practical support for using the activity, including Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes. These components can help teachers introduce the classification focus, guide discussion after rotations, and anticipate areas where students may need clarification.

Flexible Classroom Use

Use the station cards as a small-group rotation activity, with students recording their observations as they move between stations. The wrap-up can then bring the cases together so students compare classifications and explain why those categories matter when examining ecosystem processes.

This Grade 6 Alberta Science resource is especially useful when teaching Trees and Forests, species classification, ecological roles, invasive species, native species, and ecosystem relationships. Its value comes from linking classification terminology with ecological effects, giving students opportunities to explain how organisms contribute to or alter the balance of an ecosystem.
