Use the criteria to plan, select, and use the most reliable method for a scientific inquiry.
In this activity, students work collaboratively to use the criteria and a thinking strategy to select a reliable method for a scientific inquiry assessing the impact of agricultural fertilizers on a local body of water. These thinking tools can be used by students to select reliable methods for inquiry in multiple contexts. While this activity uses examples related to water quality, other examples could be used to help nurture the competency of planning and conducting.
Select a local body of water near agricultural land where students can use their selected methods to conduct the inquiry. At the conclusion of the study, you might have students consider their obtained results as they revisit the reliability ratings for their chosen method.
This activity assumes a working knowledge of the effects of agricultural fertilizers on nearby bodies of water, including its effect on levels of phosphorous, nitrogen, dissolved oxygen, and the effects of eutrophication on plant and animal species.

Throughout the activity consider how well students:
Guide students in using the “Assessing my ability to select a reliable method for scientific inquiry” rubric during the activity.
Working in small groups, students role-play various positions at a fictitious energy company and explore the challenges...
