Digital sources for environmental investigations become concrete in this Grade 6 Alberta Science learning stations activity. Students work as data detectives as they examine how different digital sources can provide evidence for investigating environmental events and consider what makes a source useful for a particular investigation.

Investigating Digital Evidence

The activity focuses on choosing and comparing sources rather than treating all digital data as interchangeable. Students identify how sensors, archives, radar, and satellite products contribute different kinds of evidence. They also examine the source information that determines whether data can answer an investigation question.

• Identify digital sources used in environmental investigations
• Consider metadata when evaluating a source
• Examine why time coverage and spatial coverage matter
• Recognize the importance of data format when selecting evidence
• Compare evidence supplied by sensors, archives, radar, and satellite products

How the Learning Stations Work

Students rotate through station cards and record their thinking on a station recording sheet. After working through the cases, they complete a station wrap-up that brings the evidence and source-selection ideas together. This structure gives students practice applying the same evidence-evaluation skills across different examples instead of considering a digital source in isolation.

The station format works well for small-group rotations, an evidence and investigation lesson, or structured practice with digital data sources. It can also support class discussion about why the source chosen for an investigation affects what conclusions can reasonably be drawn from the available evidence.

Teacher Support Included

The Answer Key PDF includes a Teacher Guide designed to support lesson delivery and follow-up discussion. It provides learning objectives, teaching tips, discussion questions, and common mistakes, giving teachers guidance for introducing the activity and addressing misconceptions that emerge during the station work.

Why These Skills Matter

Environmental evidence increasingly comes from multiple digital systems. By comparing sensors, data archives, radar, and satellite products while paying attention to metadata and coverage, students practice making reasoned choices about evidence. The activity keeps the focus on a central investigation skill: selecting digital information that fits the question being studied.
