With three different types of water to test, fifth graders are making observations about how screen, coffee filters, and sand/gravel stand up to contaminants.
Collecting both qualitative and qualitative data, they are seeing how the clarity of the water changes as well as the length of time it takes to filter the water. How transparent can we get the water to become? How fast can we complete the process? Is faster always better? Or does the clarity of the water become compromised?
These are just some of the questions we're investigating as we'll begin to design our own water filters!
