This lesson / activity is a great way for students to integrate STEM knowledge to construct a model of Earth's natural filtration system. The article provided good questions to ask students to get them thinking about the concept. However, I would like to have seen more information as to what materials will be effective and appropriate with different age levels and more information as to why it is important.

Great idea to test problem solving and science inquiry! Yet, I would use this idea during my soil unit. Students do not realize what a filter is and the different types of filters. How does different filters and different products effect our water system/cycle? Let the student(s) create a filter is genius!

This lesson illustrates a good way to demonstrate water filtration using almost completely every-day items. The only thing is that it seems rather limited in what the students can do to experiment, but tweaking it would come in whichever classroom it's adapted to.

Students in grades three through eight would enjoy this inquiry activity that has them designing, planning, building, and using their own water filters. If you have other resources that provide more direction in what materials would be suitable to provide students, rubrics for evaluating filters, etc., then this article is a good supplemental one. The authors provide many questions that teachers can ask their students as they go through the process of making and testing their water filters.
