Human impacts on Earth systems and biogeochemical cycles is the focus of this Grade 6 Science worksheet on Earth and human activity. Students examine how land-use change, fossil fuel combustion, agriculture, and waste management can alter Earth systems over time, while building cause-and-effect reasoning about environmental change.

What Students Explore

The resource connects human activity to changes in biogeochemical cycles and climate drivers. Students identify relationships between specific human actions and environmental observations, then consider why impacts can vary across locations because ecosystems and environments differ spatially. The lesson provides opportunities to apply environmental science concepts rather than simply recall definitions.

Student Tasks

Students work through a varied set of question and activity formats, including multiple-choice questions, true/false statements, short-answer responses, a dialogue, matching, a cloze passage, a labeled diagram, a reading passage, and an essay. These tasks give students practice explaining environmental cause and effect, interpreting information, connecting human actions with Earth-system changes, and communicating their reasoning in different forms.

Teacher Support Included

• Student worksheet covering human impacts on Earth systems and biogeochemical cycles.
• Separate Teacher Guide PDF with learning objectives, teaching tips, discussion questions, and common mistakes.

Classroom Use

Use this Earth and human activity worksheet as guided classwork, independent practice, a lesson review, or a written check of students' environmental science reasoning. The mix of selected-response and written tasks also gives teachers multiple ways to see how students connect human activities with changes in Earth systems.

NGSS Framework

The resource is identified with the NGSS framework and focuses on observable reasoning about how human activities affect Earth systems. The included Teacher Guide supports instruction with discussion prompts, teaching guidance, and attention to common student mistakes.
