  3. Group Problems • Three to four students per group • 5–10 minutes for group discussion and 5 minutes for the presentation of the results • One student will take notes of the problem solving strategy, different steps in tackling the problem and the final solution. • The other students should be prepared to explain their results to the class or another group.

  4. A Pictorial Introduction • Where are we in the Universe? • The size of Earth, the Sun, the solar system, the “Milky Way”, and the entire universe • Is life on Earth unique? • The universe is the totality of space, time, matter, and energy. • Astronomy is the study of the universe. • Astronomical tools and techniques Center for Solar-Terrestrial Research
