Population growth and consumption stress resources is the focus of this Grade 7 Science worksheet on Earth and Human Activity, giving students practice connecting human demand with changes in water, energy, land, raw materials, ecosystems, and resource cycles.

Students examine how both population growth and per-capita consumption can increase demand for essential resources. They trace cause-and-effect relationships, consider how greater demand can affect ecosystems over time, and evaluate actions that may reduce pressure on biodiversity, freshwater, and carbon emissions.

What students practice

• Explain how population growth and per-capita consumption change resource demand.
• Describe effects of increased demand on ecosystems and resource cycles.
• Use quantitative ideas and cause-and-effect chains to compare environmental impacts in different regions.
• Evaluate actions that could reduce pressure on biodiversity, freshwater, and carbon emissions.

Student tasks and assessment variety

The worksheet combines multiple-choice questions, true-or-false statements, short-answer responses, a dialogue, matching, a cloze passage, a labeled diagram, a reading passage, and an essay. This range gives students opportunities to recall concepts, interpret relationships, communicate scientific reasoning, and construct longer responses about population and consumption.

What the teacher receives

• Student worksheet: Practice covering population growth, per-capita consumption, resource demand, ecosystem effects, resource cycles, biodiversity, freshwater, and carbon emissions.
• Teacher Guide: A separate PDF with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes.

Practical classroom use

Use the worksheet as independent science practice, a lesson activity, or an assessment opportunity within an Earth and Human Activity unit. The varied response formats also provide natural points for class discussion and written scientific reasoning. The separate teacher guide supports preparation, discussion, and identification of common student misconceptions.

For teachers covering NGSS content related to Earth and Human Activity, this resource connects population and consumption patterns to environmental pressure through concrete resource and ecosystem examples. It gives students a structured way to move from identifying resource demand to explaining consequences and evaluating possible responses.
