Ecosystem evidence and environmental decision-making take centre stage in this Grade 7 Science learning stations activity for Alberta's Interactions and Ecosystems topic. Students work with ecosystem observations and monitoring evidence, explain ecological changes, and consider how scientific evidence can inform responsible environmental decisions.

Investigate Evidence, Then Make Decisions

The station-based structure moves students beyond simply identifying ecosystem concepts. Students record evidence from station cards and complete a wrap-up that connects observations, investigations and long-term monitoring with decisions about ecosystems. The work emphasizes an important scientific idea: environmental decisions may involve uncertainty, benefits and possible unintended effects.

Students practise how to:

• Use observations and monitoring evidence to explain changes in real ecosystems.
• Compare investigations with long-term ecosystem monitoring as sources of evidence.
• Evaluate proposed ecosystem actions using available evidence.
• Consider uncertainty when interpreting environmental information.
• Recognize benefits and possible unintended effects of ecosystem decisions.

What Teachers Receive

• Station recording sheet for students to organize information from each case.
• Station wrap-up for connecting evidence across the activity.
• Case-study station cards for the classroom rotation.
• Teacher Guide included in the Answer Key PDF.

The Teacher Guide adds practical support with Learning Objectives, Teaching Tips, Discussion Questions and Common Mistakes. This makes the activity easier to introduce, facilitate and discuss without requiring the teacher to build supporting guidance separately.

Flexible Classroom Use

Set the cards around the room for a science learning stations rotation, or use the materials to structure a whole-class investigation of ecosystem evidence. The recording sheet gives students a consistent place to capture information as they move through the cases, while the wrap-up provides an opportunity to connect evidence and environmental decision-making after the rotations.

This resource is especially useful when teaching Interactions and Ecosystems because it links ecological observations to scientific reasoning rather than treating ecosystem knowledge as isolated vocabulary. Students examine how evidence can support explanations, compare different ways of gathering information, and evaluate actions while acknowledging uncertainty and possible consequences.

Designed for Grade 7 Science within an Alberta framework, the activity provides focused practice with ecosystem monitoring, evidence-based explanations and responsible environmental decisions.
