Human impacts on Earth systems are the focus of this Grade 6 Science worksheet resource, helping students trace how human activities can affect the atmosphere, hydrosphere, geosphere, and biosphere.

Students examine real-world environmental situations involving pollution, land-use change, resource use, habitat destruction, and human effects on natural systems. The activities move from identifying direct impacts to tracing connected effects across multiple Earth systems, giving students practice with the cause-and-effect thinking needed to explain environmental change.

What Students Practice

• Match human activities with the Earth system and environmental impact they affect.
• Classify changes as natural or human-caused.
• Trace cause-and-effect chains from an initial human activity through later environmental effects.
• Distinguish immediate effects from secondary effects in environmental scenarios.
• Use a word bank to complete connected environmental effect chains.
• Predict what may happen next when human activities change land, water, or habitats.
• Connect changes in one Earth system to effects in another.

Classroom Use

Use the worksheet for independent practice, science review, small-group work, or a follow-up activity after teaching human impacts and interacting Earth systems. The progression begins with accessible identification and matching tasks before asking students to trace consequences and apply cause-and-effect reasoning to familiar environmental situations.

The resource gives students repeated opportunities to work with concepts such as air pollution, water pollution, deforestation, farming, urban development, habitat loss, warming, soil changes, and effects on living things. Clear scenarios and structured response spaces keep the focus on scientific reasoning rather than unnecessary visual or numerical complexity.
