How would I go about filtering water for a science fair project?
My science fair project idea is: How clean is your water? but I don't just want to send the water through a water filter, we are testing four different types of water and I want people to visibly see what water is cleaner. Is there any way we can test
You can get one of the water testing kits like the testing paper strips. You just dip it in water and it turns colors that can be compared to a chart.
Or you can send things with obvious color that are small particles through the filter.
