Key Elements: Response illustrates the cell in Environment 1 and the direction of water flow in this environment. Response illustrates the cell in Environment 2 and the direction of water flow when cell is in this environment. Response correctly describes the resulting change in the cell in river water. Response models what will occur if the cell remains in 100% water for 12 days. Response includes all four key elements. 4 Points Response contains no scientific errors. Response includes three of the four key elements. 3 Points Response may include scientific errors. Response includes two of the four key elements. 2 Points Response may include scientific errors. Response includes one of the four key elements. 1 Point Response may include scientific errors. Scoring Notes The following are examples only. All reasonable, valid responses should be accepted.
