Summary
In this multi-day culminating lesson, students construct, test, and evaluate their own desalination devices using the engineering design process. Building on prior lessons about water scarcity, filtration, evaporation, and biomimicry, students collect data on device performance, assess sustainability and efficiency using defined criteria, and propose evidence-based design improvements. Through collaborative testing, reflection, and presentation, students develop a deeper understanding of desalination as a real-world sustainability challenge and practice systems thinking, data analysis, and iterative problem solving.

Safety Precautions, Hazards, and Risk Assessment
-Saltwater is non-potable; tasting is prohibited
-Care required when handling plastic containers, hydrometers, and sunlight-exposed setups
-Devices placed securely to prevent spills
-Hand washing after activity encouraged
-Overall risk level: Low to Moderate with standard classroom supervision
NGSS Standards, if applicable
3–5-ETS1-2: Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints.

3–5-ETS1-3: Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
