1 Semester Goals What is science? How does it work? –Why is science different from philosophy or religion? –Why is a scientific “theory” different from a conspiracy “theory?” Learn about the Scientific Method through study of Astronomy: 1.How do we know there are planets around other stars? 2.How are stars and planets born, live, and die? 3.What are black holes? 4.Where did the Universe come from and where is it going? 5.Are we alone in the Universe? Prepare you to live in a scientific world. “Scientists discover giant black hole. Should I be afraid?”

1 Why should I believe? How do we decide what to believe is true? –Astrology. –Astronomy. –UFOs. –Search for Extraterrestrial Intelligence (SETI). –Creationism. –The Big Bang. Why should you believe one over any other?

1 Astrology The date, time, (and place) of birth affect: –Your personality –Your actions –Events that will affect your life Horoscopes appear in most papers. Millions of people read them daily. Is it real? Is it fiction? How do we know?

1 Horoscopes Horoscopes have been made for each of you. Do not share your horoscope with any one else. Does this horoscope describe you?

1 Does it work? Be careful what you are testing. Any good prediction can be tested. Science is the art of making good predictions.
