Did you know that 1.6 million people die annually from unclean drinking water? In this mini unit, students work to solve this world health crisis using STEM concepts of
water filtration and treatment to solve 3rd world problems. In this mini unit, students learn about drinking water quality issues in 3rd world countries. Students then research, plan, and build their own water purification devices. Devices are tested and results are compared (turbidity). Then comparisons are made among student-made water filtration devices, natural cycles, commercially available devices, and processes used in water treatment plants. Students then participate in a project-based assessment to integrate knowledge of existing filtration devices, water treatment plant operations, and natural cycles to plan and design the most effective water treatment plant possible.
This mini unit is directly aligned with the following NGSS Standards:
Overarching Student Learning Objectives:
