The WSI is a fun and easy way for students and adult community members to become Water Scene Investigators and really save water! This activity starts with an eye-opening examination of water use and water-use technology. It includes installing a simple water-saving technology in the home: a faucet aerator. WSI Investigators measure their faucets’ average flow rate before instillation of the new aerator and after the installation of the new aerator. They report their water savings here. And they see how their actions compare to and combine with others’ to save more water in Arizona.
The WSI program can be used by educators, businesses, public agencies, non-formal education, and the community to engage 5th through 9th grade students in a project focused on water conservation, efficiency, and water auditing. The WSI is a two‐day, in‐classroom project; the two days can be separated by a week to allow for homework completion. And it may be easily adapted for non‐classroom use, whether that is in community groups or clubs, with youth or with adults.
The WSI inspires simple actions that result in real water savings. This year, students involved in APW programs that use the WSI activity in and out of school saved a projected 18,973,169 gallons of water through applying their knowledge and installing water efficient devices.
The WSI is a participatory method of learning STEM skills. Students learn effective ways of conserving water indoors, while developing specific STEM skills. Students utilize math skills by measuring water use before and after the installation of new faucet aerators, and then calculating annual water use in gallons per year using mathematical thinking skills. They gain critical awareness of scientific principles of measurement, accuracy, prediction, observation, problem solving, analysis and well-reasoned conclusion-making based on data-driven evidence as they perform the faucet audit with their own hands and minds.
