Fourth graders were asked to design a solution to the problem in Greentown. Some of the answers could possibly happen, and were therefore classified as realistic. Some of their solutions, after some in-depth discussion, were deemed unrealistic or unable to happen. Students had the chance to argue their viewpoints and come to a group consensus as to which solutions were realistic and those that were not!
Realistic solution: Develop a technology to clean up the pollution in the pond.
Unrealistic solution: Move the pond to a new location.
