Urban Landscape - Take I

Students created cities out of cardboard, index cards, and foil.  The groups were quite imaginative!

Then, they were given 15 minutes to plan how they would use the technologies we have explored to keep our pollutants out of their rivers.  These are their urban landscapes with their pollution reducing technologies:

 Uh oh!  Pollution has landed!  The students chose the sequins to represent plastic litter, the sprinkles to represent dog poop, food coloring to represent general chemicals, and dish soap to represent gas & oil from cars.

After 300 sprays of water, there was very little pollution in the rivers, but still more than we would like.  Tomorrow, the groups will be able to improve their plans, and we will test their technology again.
