After a demonstration by Mrs. Brinza showing how water travels through the land, fourth graders quickly discovered how pollution could travel from one place to the next. Just because pollution was dumped into river didn't mean it couldn't end up on a farm down the block. And just because someone dumped something behind a school didn't mean it wouldn't make an appearance at a lake far away!
The students needed a way to measure if a change had taken place in either the soil or the land. And that's when knowing about pH came into play! Testing various household liquids, fourth graders then extended their new knowledge into testing water and soil samples. They were able to identify changes and the possible pollution culprits!
