This design brief has a complete lesson plan included. It can be used as a preview lesson for an erosion unit or as a post to complete a unit on erosion. Students will use the scientific method to determine the problem, predict a solution, test and evaluate. Suggested materials are listed for the design, but others may be added as available. My students were excited and engaged in this unit and were challenged to look for methods of controlling erosion in their own environment after the completion of the design brief.
