Sustainability strategies are the focus of this Grade 6 Science resource on Earth and Human Activity, giving students opportunities to examine how human choices affect Earth system processes over time. Aligned to the NGSS framework, the resource connects population trends, per-capita resource use, conservation, renewable energy, circular resource use, and land-management strategies.

What students investigate

Students explain how changes in population and per-capita resource use can influence Earth system processes over time. They compare sustainability approaches and consider the trade-offs that can arise when environmental, economic, and social priorities compete. The resource also asks students to use indicators to measure progress toward long-term sustainability.

Varied practice for science learning

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 mix gives students practice with factual knowledge, comparison, explanation, interpretation, and written reasoning while staying focused on sustainability decisions and Earth system impacts.

What the teacher receives

• Student worksheet: A structured set of questions and activities centered on sustainability strategies and Earth system impacts.
• Teacher Guide: A separate PDF with learning objectives, teaching tips, discussion questions, and common mistakes to support instruction.

Practical classroom use

Use the worksheet as independent science practice, a guided classroom lesson, or a review activity after teaching Earth and Human Activity. The discussion questions in the Teacher Guide can extend classroom conversation around sustainability choices, while the varied response formats provide opportunities for students to explain and evaluate ideas rather than relying only on selected-response practice.

Why this resource earns a place in your science plans

The resource brings several connected sustainability concepts into one focused learning experience. Students move beyond simply identifying environmental strategies to comparing conservation, renewable energy, circular resource use, and land management; evaluating trade-offs; and considering how indicators can show whether sustainability goals are being achieved over time. The accompanying Teacher Guide adds practical instructional support without changing the focus of the student worksheet.
