With this Build a Water Treatment Experiment Kit, kids learn about sand filters and the basics steps of water treatment: aeration, coagulation, sedimentation, filtration, and disinfection. This kit will take kids through the first four steps of the water treatment process. But since the disinfection step is not included, this water is NOT safe for human consumption.
Using the items provided in this kit, kids will Build a Water Treatment Experiment, then watch as the water is transformed from a murky, muddy mess to clean and clear. While this kit provides the science supplies you'll need, like different types of sand, alum, and more, you provide household items and adult supervision. Click to see the complete experiment and materials list.
Setting up the experiment should take about 30-60 minutes, but the filtration process takes hours. This project would work well for a multi-disciplinary approach to studying water and the challenges many people in the world face in simply getting clean water.
