Astronomy Part 1
Course Length: 1 Semester
Has Textbook: Yes
Students will begin Astronomy Part 1 by taking an in-depth look into the night sky. Students will learn about the stars, constellations, and the phases of the Moon. This course will then discuss the cycles of the Sun, which influence the Earth's climate. Students will become familiar with the origin of modern day astronomy as they learn about modern methods of measurement and observation, ground-based and space-based astronomy, and ancient instruments and techniques for observation. The course will continue with a closer look at the Sun and stars. This section of the course will concentrate on solar activity, classification of stars, star formation, and the death of a star. Astronomy Part 1 will incorporate the use of interactive labs and a textbook.
