Stars, planets, even a galaxy or two! Students will learn about constellations, star movement and how scientists have studied celestial bodies throughout history---from Ptolemy and Copernicus to work of the Hubble Space Telescope. Includes an interview with Kathy Thornton, one of the astronauts who repaired the Hubble while in orbit! Also includes a fun, hands-on activity where students will build their own sextant, demonstrating how ancient seafarers navigated using the movement of the stars.
