Students are selected to develop procedures for conducting a study on plant fertilizers. They are given data to determine which fertilizer is best for school gardens based on growth rate, size of vegetables, amount of vegetables, taste, and color. They will reassess these fertilizers during the twist incorporating safety ratings.
Students may arrange the criteria based on their team's interpretation of most important to least important. Students may have to make trade-offs based on these interpretations.
