Star Detectives Reading PacketAncient Sky Watchers Large Print Grade 2 Reading • Adapted from Where Are the Constellations? (pp. 16–22) Name: Date: The Story in the Stars Read Aloud or With a Partner Long ago, there were no electric street lamps, alarm clocks, or glowing phones. When the sun went down, the world turned completely dark. The night was lit only by campfires and thousands of brilliant stars. Ancient people watched the night sky and noticed that groups of stars stayed together like giant connect-the-dots pictures. We call these star pictures constellations. Constellations were important helpers! Early farmers had no paper calendars. When special star patterns rose in the spring, farmers knew it was time to plant seeds. When different stars appeared in the chilly fall, it was time to harvest crops. On the open sea, sailors had no GPS maps. They used the bright North Star to steer their ships safely across dark waters without getting lost. Around 1,900 years ago, a star scientist named Ptolemy lived in Alexandria, Egypt. Ptolemy wrote an important book called the Almagest. In his book, Ptolemy mapped 48 constellations. He named them after ancient myths, brave heroes like Hercules, and mighty animals like Leo the Lion. Today, all 48 of Ptolemy’s star groups are still part of the 88 constellations we recognize today!

Sky Myths Reading PacketSky Myths and Star Bears Large Print Grade 2 Reading • Adapted from Where Are the Constellations? (pp. 22–29) Name: Date: Bears, Hunters, and Secret Maps 2nd Grade Text One of the most famous shapes in the night sky is the Big Dipper. It looks like a giant soup ladle with a long handle. But the Big Dipper is actually part of a much larger constellation called Ursa Major, which means the “Great Bear.” Next to it sits Ursa Minor, the “Little Bear.” Ancient Greek myths say a king tossed the bears into the heavens by their tails, stretching their tails out long! The two bright stars at the outer edge of the Big Dipper cup are called Pointer Stars. If you draw an imaginary line through them straight across the sky, they point directly to Polaris, the North Star, sitting at the tip of the Little Bear’s tail. For centuries, lost travelers in the dark followed these pointer stars to find north. Different people looked at the very same stars and told different stories. Native American storytellers saw the stars of Ursa Major not as one bear, but as a giant bear being chased by three hungry hunters. Later, during the Middle Ages, brilliant Arabic astronomers studied the stars and gave many bright stars Arabic names we still speak today, like Betelgeuse and Rigel!
