The Ancient Heavens: Exploring the History of Astronomy Lindsay Bartolone Adler Planetarium, Chicago Donna Governor Forsyth County GA Schools For the ancients, the heavens were of paramount importance in agriculture, religion, divination and tracking time. By understanding the roots and origins of Astronomy, and how ancient civilizations studied, used and applied this science, students can begin to appreciate what early astronomers contributed to our understanding of the world and our place in the universe. The History of Astronomy is important in developing an understanding and respect for not only what we know, but how we learned it. By encompassing a perspective of Astronomy that is historical, students develop a greater appreciation for the content they learn. From tracking the motion of the sun and stars, to the legends of Native Americans, these activities help participants appreciate not only what we know, but how we know it. Who were these ancient astronomers? Throughout human history people of all cultures have looked to the sky to improve their daily lives. What did they know? QuickTime™ and a YUV420 codec decompressor are needed to see this picture. The Mayans lived in the area in Central America which now consists of Yucatan, Guatemala, Belize and southern Mexico. They were accomplished astronomers and like other cultures, carefully observed the motion of the Sun, stars and planets. Native American Astronomy The center of the Mississippian culture was at Cahokia, at the juncture of the Mississippi, Missouri, and Illinois Rivers. In the 1960’s a celestial calendar was uncovered. Woodhenge is a solar horizon calendar that enabled the Mississippians to track the sun's movement as a way of determining important dates.

Mark the rising and setting sun on the solstices and equinox. The Multi-Cultural Moon The Moon is bright in the middle of the night. It is big and round. It’s in the sky. It has highlands and maria. It makes me smile. I like the Moon. Is the Moon made of rock? - Samantha Shroyer - first grade - Fall 2002 Moon Tales QuickTime™ and a YUV420 codec decompressor are needed to see this picture. Myths from around the world can be used to help even the youngest student understand concepts in astronomy. Make a Moon Finder The phase and position of the moon can be used to tell time, or the time and position can be used to help students learn the difference between a waxing and waning crescent. Star Stories - Orion The Hunter Greek/Roman The Alligator - Brazil Pata & Criminal Peru Tsan - Defender of Farmers - China Canoe of Tamarereti New Zealand Constellations & Coordinate Geometry Whether students are working with simple X-Y coordinates, or Cartesian Coordinates on a four quadrant grid, cross curricular connections include math. Star Stories Integrated curriculum activity! Use sticky stars Determine Coordinates Write Story Swap! Find Coordinates Write a story Compare Versions! Keeping a Star Journal Pawnee Mudlodge • The night sky was viewed through the smoke hole of the mud lodge. This celestial calendar was not dependent on the Sun’s position, but on the appearance of certain constellations at specific times. Comparing Constellations Constructing Star Wheels with both the traditional and Pawnee constellations can help students to understand that all cultures depended on knowing the stars and constellations. Polynesian Astronomy Hawai'iloa is said to have discovered the islands during a long fishing trip. Hawai'iloa's navigator, Makali'i, steered in the direction of Iao, the Eastern Star, and hoku'ula, the red star (perhaps the rising Aldebaran). After replenishing his supplies, Hawai'iloa returned home and brought his family back to Hawai'i, again using the fixed stars as guides. Celestial Navigation Use the Hawaiian Star Compass to find your way Experience an online simulation at Wayfinders: http://www.pbs.org/ wayfinders/ Learn the Hawaiian name for the stars Advances by Arabic Astronomers QuickTime™ and a YUV420 codec decompressor are needed to see this picture. Celestial Navigation is as useful in the deserts of the middle east as in the tropical waters of the Pacific. Common names for stars are often Arabic, recognizing their contributions to ancient astronomy. Bibliography & Resources Lasky, Kathryn.
