This lesson is designed to help students understand that role that water plays in shaping the earth. In this activity, students investigate different methods for removing pollutants from water using the properties of how water interacts with earth materials.
Water shapes the earth through the processes of erosion, deposition, and weathering. This is directly connected to how water interacts with various earth materials and this interaction creates a source of water known as ground water. This same process is how water is also able to breakdown larger rocks into smaller ones, through water penetration and freezing.
After being exposed to the problem of the lack of clean water around the world, the students will be tasked with designing and building their own water filters, mimicking Earth processes, to help provide solutions to this problem.
The Reseach Expereince for Teachers (RET) program at the Center for Bio-mediated & Bio-inspired Geotechnics (CBBG) at Arizona State University allows local, STEM-focused K-12 teachers and community college faculty to participate in cutting-edge laboratory research and use our test bed facilities. In addition, teachers engage in curriculum development to develop modules for implementing in their classrooms. This lesson was create in 2016 by Carlos Perla, a teacher participating in the RET program
