Presentation transcript:

2 Moons and Seasons Axial tilt is the reason for the seasons.

2 Goals What is science? What is the scientific method? Does the scientific method work? What does the scientific method assume? What is not a scientific argument.

2 What we see We experience astronomy daily: –Sun rise and sun set –Seasons –The Moon –Stars and planets Observing projects this semester.

2 Concept Question We experience winter in California because: a)The Earth is farther from the Sun in winter and so it is colder than summer. b)The tilt of the Earth moves California farther away from the Sun in winter so less light reaches California. c)The northern hemisphere is tilted away from the Sun in winter, so sunlight doesn’t beat down on us as much as in summer. d)The Earth’s elliptical orbit keeps us farther from the Sun for longer and so it is colder. e)None of the above.
