Human impact on Earth and the environment takes centre stage in this Grade 7 science investigation, where students examine how human activities change natural environments and affect both people and ecosystems. Rather than simply identifying environmental problems, students use environmental evidence and monitoring indicators to investigate the extent of human impacts and consider how those impacts can be reduced.

Planet Under Pressure: Human Impact Investigation is a learning stations resource focused on Earth and Human Activity. It gives students opportunities to investigate environmental change, record findings, reflect on evidence and compare approaches to balancing human needs with environmental protection.

Investigating Human Impact Through Evidence

The investigation develops three connected areas of environmental science:

• Human activities and environmental change: Identify ways human actions alter natural environments and examine the consequences for people and ecosystems.
• Environmental evidence and monitoring: Use environmental evidence and monitoring indicators to investigate the extent of human impacts.
• Mitigation strategies and trade-offs: Compare approaches to reducing environmental impacts and explain the balance between human needs and protecting natural environments.

These skills encourage students to move beyond recognising environmental issues and towards evidence-based investigation and reasoned comparisons.

What Is Included?

• ✔️ Station recording sheet: Provides a place for students to record investigation findings.
• ✔️ Station cards: Provide the station-based investigation activities.
• ✔️ Station wrap-up: Gives students an opportunity to bring their investigation to a conclusion.
• ✔️ Answer Key PDF with Teacher Guide: Includes learning objectives, teaching tips, discussion questions and common mistakes to help guide instruction.

Classroom Use and Teaching Support

Use this Grade 7 environmental science activity as a station-based lesson on Earth and human activity. Students can work through the station cards, document their findings on the recording sheet and complete the wrap-up to consolidate their investigation. The included teacher guidance provides useful preparation and discussion support, while the common mistakes section helps teachers anticipate areas that may need clarification.

The discussion questions also provide opportunities to extend classroom conversations about environmental monitoring, the consequences of human activity and the challenges involved in choosing mitigation strategies. Teachers can use the resource as part of an Earth science unit or as a focused investigation into human environmental impact.

Curriculum Connection

This resource is identified with the Next Generation Science Standards (NGSS), MS-ESS3-3. Its focus on investigating human impacts and comparing mitigation strategies makes it relevant to middle school science instruction about Earth and Human Activity.

For teachers covering environmental impact in Grade 7, this investigation brings together student recording, station-based exploration, evidence evaluation and teacher discussion support in one resource. Students get to examine the relationship between human activity and environmental protection while considering why reducing environmental impacts can involve difficult trade-offs.
