Science Co-op # 5: Dirty Water

During this week's 'dirty water' science co-op, participants learned about the cumulative effects of pollution as water runs through streams and rivers. They then applied the four-step engineering cycle to design filters to help remove contaminants form the water. Henri once again excelled during a group game of 'hangman' at the end of the session.

Some participants/contaminants took turns trying to see if they could get through the human filter
