Bring engineering and real-world problem solving into your classroom with this 10-page, black-and-white “Summer Tech Lab: Design a Smart Eco Device” worksheet pack. Designed for Grade 8, this resource places students in the role of engineers as they design and optimize a solar-powered cooler and water filtration system using algebra, functions, and modeling.

This is not a collection of disconnected worksheets. Each page builds on a consistent system where students analyze cost, output, efficiency, and constraints while making design decisions. The connected structure creates a realistic STEM simulation that mirrors real-world engineering challenges and increases both rigor and engagement.

Students progress through increasingly complex tasks, including linear functions, systems of equations, geometry, optimization, and data analysis. Each worksheet includes 10 structured questions, with the final question requiring explanation, justification, or design reasoning.

All worksheets are black-and-white, print-friendly, and formatted for US Letter (8.5 × 11). Each page includes a scenario box, data section, 10 complete-sentence questions, and one clean line-art illustration.
