Investigating dimensions of the solar system
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 a review and suggestion process as a part of an activity development workshop.
This activity has benefited from input from faculty educators beyond the author through a review and suggestion process as a part of an activity development workshop. Workshop participants were provided with a set of criteria against which they evaluated each others' activities. After the review, the authors developed a plan for revising their activities based on the feedback they received from their peers. To learn more about this review process, see http://serc.carleton.edu/quantskills/review_processes.html#2006.

Students use planetary mass and radius to calculate density and compare these quantities to orbital radius in order to assess trends and patters in the solar system. Excel is used to graphically compare the data (mass, and radius) and the calculation results (density) orbital distance. The results are used to investigate and evaluate the Nebular Hypothesis.
Context for Use
Description and Teaching Materials
Materials:A student handout (Microsoft Word 98kB Nov17 06) with introductory information and questions for the students.
A solution worksheet (Excel 29kB Nov17 06) with all the calculations keyed out.
Teaching Notes and Tips
Instructor must be sure that students apply the concepts of mass, size, and volume, especially in the calculations of density.
