STEM Challenges are a great way to get your students working collaboratively and thinking critically. In this Earth Day Challenge, students will use the Engineering Design Process to design and build a water filtration system. This STEM Challenge also includes a mini-lesson demonstrating the amount of water on Earth. The demonstration completely shocked my students, which then transitioned to excitement when they were able to work on solving the problem.
