Developing Student Ability to Ask Scientific Questions

Author Profile

This activity was selected for the On the Cutting Edge Reviewed Teaching Collection

This activity has received positive reviews in a peer review process involving five review categories. The five categories included in the process are

  • Scientific Accuracy
  • Alignment of Learning Goals, Activities, and Assessments
  • Pedagogic Effectiveness
  • Robustness (usability and dependability of all components)
  • Completeness of the ActivitySheet web page

For more information about the peer review process itself, please see http://serc.carleton.edu/NAGTWorkshops/review.html.

This activity has benefited from input from faculty educators beyond the author through a review and suggestion process. This review took place as a part of a faculty professional development workshop where groups of faculty reviewed each others' activities and offered feedback and ideas for improvements. To learn more about the process On the Cutting Edge uses for activity review, see http://serc.carleton.edu/NAGTWorkshops/review.html.

This activity is a two-part (three week) lab in which students initially develop a claim (non-scientific) and learn how to use evidence to support a claim. They then are provided with a scientific research question for which they need to make a claim supported with evidence from their own models (river/stream tables). Based on their results, they then ask a new research question, design the model, carry out their tests and report their results.



This is used in an introductory natural hazards course, but could easily be adapted for any introductory geology/geography course that deals with river processes.

Skills and concepts that students must have mastered

Students require no special skills beyond basic proficiency of reading, writing and communicating.

Description and Teaching Materials

Lab 1:

  1. Students are presented with a series of possible research questions to answer, as a team, they must select one and do research on how to support a given claim
  2. Students will need computers and internet access (or access to research materials) and white boards to present their findings to the class
  3. Students participate in a "poster session" reporting on their findings and defending their stance.
  4. Post-activity discussion can include how emotions DO influence the scientific process and how peer review/going public can help to keep scientist accountable.
Lab 2:

  1. Students are presented with two basic research questions, of which they can choose one to answer: How does slope affect a river channel or how does ground material affect a river channel?
  2. Students work in small groups to select a research question, design a way to test the claim they decide to make based on their research question and determine if they may need to revise their claim and develop a new research question based on the outcomes of their initial trials (in addition, students start to appreciate the need to control variables as best as possible and the complexities of Earth as a system)
  3. Materials are listed in the lab, the key is that they aren't told what should go into their river system, they need to decide that for themselves. Instructor input may be needed as they're developing their models. Students generally want to jump right into testing, it requires some self-regulation to assure they have a well-thought out plan prior to engaging in the actual model testing.
  4. Based on their findings, students re-match up and share their results and learn from each other what different groups did. They then take this information back to their fellow group members and develop a new research question to test. These must be approved by the instructor.
  5. Once approved, students test new research questions, and report out on their results in a "poster session". Students receive feedback from their peers.
  6. If time allows, ask students to consider how their claims changed as they worked on new data and how the need to go public forces them to make their details clear.

Teaching Notes and Tips

In lieu of clay, I have used cornstarch, which is much cheaper.

These labs typically take three full lab weeks, but I find after, they are better primed to talk about the use of data in different analyses and have a better sense of the subtleties and complexities of the scientific process. In addition, they begin to appreciate the importance of clear lab notes.


I have both individual assessments and larger group assessments:
