Course Material 3A: Challenge Problems
As a culminating activity, students are asked to use their EMS model to solve one of several "challenge problems." Each problem contains data about celestial or seasonal phenomena that students haven't encountered before. For example, the students might be asked to explain phases of Venus or eclipses on a different planet. The challenge for the students is to use their EMS model to explain these new scenarios. Successful completion of each problem involves:
In addition, each problem will require students to:
Example: In another problem, students are asked to alter a component of their EMS model, the tilt of Earth on its axis. They are asked to predict what seasonal phenomena would look like if Earth were tilted at 0° rather than 23.5.
In this final activity, the students will work again in groups of two or three to produce a single product. Their final product will be a poster that answers all aspects of the particular challenge question posed and gives both written and graphical justification for their answers. In addition, each student group will present its work to the class during a scientific poster session.
