Activity 01
Design Challenge: Water-Saving Device
Provide recycled materials for pairs to design and build a prototype, such as a greywater system or drip irrigation model. Students test their devices with measured water volumes, record efficiency data, and present improvements. Follow with a class vote on most innovative solution.
Evaluate what technologies can help us conserve water in arid regions.
Facilitation TipFor the Design Challenge, provide only low-cost materials to emphasize creativity over complexity and keep the focus on water-saving function.
What to look forPresent students with three different water conservation technologies (e.g., low-flow showerheads, drip irrigation, xeriscaping). Ask them to write one sentence for each, explaining how it conserves water and one potential challenge to its implementation.
