It’ll be on Chapters 1 and 2. And you won’t be allowed to take the test until I have the syllabus acknowledgement. © 2005 Pearson Education Inc., publishing as Addison-Wesley announcements • How many clicker points do you have? You’ll know soon, I’m going to post the data later today on myUCF grades. • Please note that if you’ve been answering clicker questions incorrectly, it definitely behooves you to figure out why you were wrong, even if you don’t wind up losing points toward your grade. Clicker questions are good test questions! © 2005 Pearson Education Inc., publishing as Addison-Wesley announcements • Observatory extra credit -- tomorrow night. If you go, make sure you read the syllabus first. “Fill out the form while you are at the observatory, and turn it in to the appropriate place (i.e. "the box" at the observatory). Other AST 2002 students will be at Robinson doing a similar assignment, but they'll be using a slightly different form. You can use that form for this assignment, but you really ought to use the form that's attached to this syllabus. If you forgot our form, find a friend that has the form and answer the questions on the other form as if you had the right form.” © 2005 Pearson Education Inc., publishing as Addison-Wesley © 2005 Pearson Education Inc., publishing as Addison-Wesley Chapter 2 Discovering the Universe for Yourself • 2.1 - Celestial Sphere • 2.2 - Seasons • 2.3 - Moon Phases & Eclipses • 2.4 - skip for now © 2005 Pearson Education Inc., publishing as Addison-Wesley Section 2.3 The Moon Two extremely important, fundamental concepts here: • Phases of the Moon • Eclipses -- Lunar and Solar There are tutorials about these two concepts in MasteringAstronomy.
