    In this assignment you will see several of the question types found in Foundations of Astronomy 12e by Michael A. Seeds and Dana Backman published by Brooks/Cole Publishing.

    Question 1 is an assignable Active Figure Exercises (AF). Active Figures Exercises help students visualize astronomy with animations and quiz questions.

    Question 2 is a Guidepost Question (GP). Guidepost questions are useful to stimulate student interest and attention both during the classroom lecture or while reading the chapters. They are the sort of questions an intelligent person on the street might ask about the chapter topics.

    Question 3 and 4 are Reading Exercises (RE). Active is better than passive! These exercises promote active, questioning reading of the materials. Reading Exercises test for comprehension of the text material. Instructors can assign these questions as incentive to the students to keep up with the reading assignments.

    Question 5 is a Ranking Task Exercise (RTE).

    Question 6 is a Review Question (RQ). Review Questions actively reinforce the major points, facilitating recall and understanding.

    Question 7 and 8 are Problems. A direct match to the textbook, these problems include an immense range of distances, times and masses found in astronomy. These straightforward problems in this text promote active calculation of numerical answers essential for true understanding. This demo assignment allows many submissions.
