Desalination Design Challenge: 03 Focus on Filtering

In this lesson, students investigate how water filtration improves access to clean drinking water and protects public health. After reviewing real-world filtration devices used globally, students apply ideas from biomimicry and sustainability to design their own water filter using readily available materials. Through sketching, peer feedback, and design revision, students practice the engineering design process while considering how nature-inspired and sustainable solutions can reduce waterborne disease and improve freshwater access.
