Fourth graders had to not only decide the materials to use, but the order in which they would use them, too. Since cleaning up an oil spill is a very expensive process, they realized just how quickly the money could disappear. They will have a chance to redesign their process, noting how they could better meet the criteria of the challenge. Should they spend less but risk impacting the ecosystem more? Or should they spend more and impact the ecosystem less? YOU DECIDE!
