Investigating dimensions of the solar system
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.
