One of the presenters introduced us to her crumpled paper activity. Sadly, I don't remember the specifics but I will outline what I remember below. This activity provides a neat explanation of runoff. Materials: washable markers spray bottle with water paper Procedure: In a small group, crumple a piece of paper. Color various regions on the crumpled paper: city dump- red neighborhood that uses fertilizers (etc) Take the spray bottle and saturate the paper so the markers run. Discuss observations: how does runoff lead to pollution of rivers and groundwater?
I'm just a science teacher sitting at my computer generating and finding ideas to make learning more enjoyable.
