Roll and Read (Blue) 1 2 3 4 5 Suppose you are being driven to a soccer match, but your dad doesn’t know his way. Up in space a satellite transmits a signal. The satellite locks onto the car’s position and sends back directions. A galaxy may include hundreds of billions of stars. Galaxies contain gas and dust, and are held together by gravity. The two stars in the bowl are called the Pointers because they point to the North Star. The famous star is the North Star. The famous set of stars is the Big Dipper. Of all the early explorers, Christopher Columbus is probably the most famous. He is known both for the places he sailed to and he different groups of people he met on his travels. With dead reckoning, a captain would start sailing from a known point and measure out each day’s course and distance. Each day’s ending position would be the starting place for the next day’s measurement. Navigators used a magnetic compass to measure the course. The North Star is sometimes covered by clouds. And the horizon can be hard to locate at night because of darkness. Some people believed that two children were playing with his lenses and put two of them together. One night in 1610 Galileo noticed four objects near Jupiter that no one had seen before. What Galileo had discovered was Jupiter’s moons. Those “stars” were later identified as Saturn’s rings. That interest led him to design a reflective telescope that used reflecting mirrors instead of lenses. In Newton’s design a curved mirror was angled to reflect light through a side eyepiece. These telescopes were refractive. Their front lens bent, or refracted, light. Astronomers are scientists who study the universe. Constellations are groups of stars that make up shapes in the sky. In Columbus’s time the quadrant was the most important tool in celestial navigation. Your latitude is your distance either north or south of the equator. Columbus also used celestial navigation techniques. If you roll a 6, choose 1 block to read.
