Energy sustainability trade-offs give Grade 11 Science students a practical way to examine how energy system decisions balance efficiency, cost, safety, and environmental impacts. This resource focuses on evaluating designs at the system level rather than judging performance from a single component.

Explore Energy System Decisions

Students examine how energy efficiency, cost, safety, and environmental impacts interact when evaluating energy system designs. They also consider how energy storage changes demand timing and influences overall system sustainability. The activities require students to evaluate design choices using multiple criteria, helping them connect individual performance factors to broader system-level outcomes.

The worksheet includes multiple-choice questions, true/false questions, short-answer responses, a dialogue, matching, a cloze passage, a labeled diagram, a reading passage, and an essay. These activities provide varied opportunities to identify concepts, interpret energy-system situations, explain relationships, and justify evaluations of design choices.

Included Teacher Support

• Student worksheet focused on energy sustainability trade-offs
• Separate Teacher Guide PDF with learning objectives, teaching tips, discussion questions, and common mistakes

Bring System-Level Thinking Into Class

Use this Grade 11 science worksheet during an Engineering & Technology lesson, for independent practice, guided classroom work, review, or discussion. The teacher guide supports instruction by providing practical teaching tips and discussion questions while highlighting common mistakes students may make when evaluating complex energy-system choices.

Rather than isolating one measure of performance, students consider how several criteria interact. They explore the role of energy storage and demand timing and apply system-level thinking when evaluating sustainability. This makes the resource useful for building reasoning around realistic energy design decisions where improving one factor may affect others.
