A fun, wet-STEM lab where students construct water filtration columns using simple materials. Directions to set-up and run the activities are completely described and include instructions how to use the scientific method when measuring how fast water can flow through each column. The packet also includes an easy-to-setup inquiry activity where students filter a vinegar solution to determine if filtering can remove acid (litmus or pH paper required). More advanced columns that use double layers are also described. The result table is provided and can be a stand-alone assignment or can be incorporated into an interactive laboratory notebook.
