Write out the definitions of each of the listed key ideas for yourself. Try to do this without the help of the book. Afterward, go back and use the book to check your answers and study the key ideas you missed the first time through. On separate sheets of paper answer the Review Questions. Answer Advanced Question 28 on page 39. Finally, do Observing Project 57. b. Log into the publisher’s website for our book at http://www.aw-bc.com/astronomyplace/ and do the tutorials on Kepler’s Laws. Take the multiple choice quizzes for Chapter 3. c. Working with your group members, research and prepare a report on one current or recent NASA exploratory mission to an object in the Solar System. Include in your report the purpose of the mission, the scientific instruments used, the challenges posed by exploring this object, the scientific questions being explored, and the results obtained thus far. d. Re-read the section in chapter 2 on Eclipses. Then, research the Solar and Lunar Eclipses that will occur this year. Consider using the excellent website by Fred Espansk, at http://sunearth.gsfc.nasa.gov/eclipse/OH/OH2005.html. Note specifically what did/will observers here in the SF Bay Area see of each eclipse? Why did we see (or not see) the eclipses? How long did the eclipses last? What do you notice about the interval between the solar and lunar eclipses during the two eclipse seasons this year (April and October)? That is, consider the eclipses that occurred during one of the seasons. How many days elapse between the eclipses? What about the length of time between these two eclipse seasons? Can you create a hypothesis to explain why these intervals make sense? How can you TEST your hypothesis? What additional data would help you confirm that you are right or wrong? Go ahead and find that data! e. Research Project: submit a one-page proposal via email or hard copy to your instructor and/or classmates as directed in the course syllabus. Based on feedback from your instructor and/or classmates, submit a six-page, 12 point, typed and doubled spaced paper on an area of current astronomical research not already covered in detail in the required course reading material. In lieu of a formal paper, you may create a web site or power point presentation of equivalent length and content. 2. Methods of Evaluating Student Progress a. Midterm and final exams b. Individual and/or group projects and reports c. Homework assignments d. Constellation and online quizzes e.
