Science co-op - Dirty Water

This week at science co-op, we played with dirty water!! The talk was all about pollution, and all of the many ways our lakes, rivers and streams are contaminated every day. They made a filter out of their own bodies, and learned about particulate, filtrates, and residue, and then built their own filters to try and clean out the debris.

The water was still a rather un-natural blue when it came out of their filters, but was looking a whole lot better than when it went in!
