Slide 4 Scale Scale Description 4 Through independent work beyond what was taught in class, you could: investigate the location of seasonal constellations in the local sky. predict location of constellations at future times. determine the celestial equator, latitude and position of the Pole Star for a given position on the Earth. determine the distances of stars in a given constellation to each other and to Earth. 3 You will be able to: describe and apply the coordinate system used to locate objects in the sky. distinguish the various methods of measuring astronomical distances and apply each in appropriate situations. 2 You will be able to: determine the meaning of symbols, key terms, and other astronomy specific words and phrases as they are used in context to relevant topics label diagrams with degree measurements describe how or why different units of measurement are needed for distances in space 1 You will be able to label diagrams with degree measurements list the different units of measurement needed to measure distances in space Slide 5 Question 2 What is the path that the Sun, Moon, and planets follow through the constellations? a) the celestial equator b) the north celestial pole c) the ecliptic d) the zodiac e) the Milky Way Slide 6 a) the celestial equator b) the north celestial pole c) the ecliptic d) the zodiac e) the Milky Way Question 2 What is the path that the Sun, Moon, and planets follow through the constellations? The ecliptic also marks the plane of Earths orbit around the Sun. Slide 7 Stars in a constellation are Question 13 a) in the same part of the sky. b) usually equal in brightness. c) about the same age. d) about the same distance away. e) physically close to each other.. Slide 8 Question 13 a) in the same part of the sky. b) usually equal in brightness. c) about the same age. d) about the same distance away. e) physically close to each other. Stars in a constellation are Stars within a constellation might be of very different ages, diameters, types, and luminosities. Slide 9 Slide 10 Have one person from each group read the Polestar paper to the rest of the group As a group, answer the two questions at the bottom of the paper in your journal. (dont worry about writing the question) Slide 11 Slide 12 1. Use the pointer stars of the big dipper 2. Look due North, then at your latitude. Florida coordinates: 28.1000 N, 81.6000 W 10 of sky = approximately 1 hand *Example: In New York, Polaris is located 41 degrees above the northern horizon, which also corresponds to the latitude of New York. *At the North Pole, you would find Polaris overhead. *At the equator, Polaris would appear to sit right on the horizon. *If you travel to the north, the North Star climbs progressively higher the farther north you go. When you head south, the star drops lower and ultimately disappears once you cross the equator and head into the Southern Hemisphere. Ways to Find the North Star Slide 13 Slide 14 Star Trails Above Mauna Kea Slide 15 Petroglyphs and Star Trails in the Teimareh valley, located in the Zagros Mountains of central Iran Slide 16 Star trails and Nauset Lighthouse, Cape Cod Slide 17 Star trails in Juneau, Alaska Slide 18 Figure 1.12 Slide 19 a) the Earth orbits the Sun. b) the Moon orbits the Earth. c) stars are in constant motion. d) the Sun orbits the Earth. e) the Earth spins on its axis. Question 1 Constellations appear to move across the sky at night because Slide 20 Question 1 1) the motion of Earth around the Sun 2) the motion of the Moon around Earth 3) the motion of Mars around the Sun 4) the motion of the constellations around Earth 5) the spinning of Earth on its axis What motion is responsible for the apparent motion of the constellations (east to west) across the sky? a) the Earth orbits the Sun. b) the Moon orbits the Earth. c) stars are in constant motion. d) the Sun orbits the Earth. e) the Earth spins on its axis. Question 1 Constellations appear to move across the sky at night because The Sun, Moon, planets, and stars all appear to rise and set because our planet rotates once each day.

Figure 1.15 Slide 22 Slide 23 Read group article: constellations (2 pages) At the bottom of page summarize your notes by answering the questions from the beginning of class yesterday and adding at least 3 other important facts. What is a constellation? Why are constellations useful? How has the use of constellations changed over time? Summarize your notes! Slide 24 Make your own constellation. Tape the star chart into your science journal on the left side On the picture, outline the stars that form the shape. On the top of the page, write the name of your constellation. On the right side, write the story of the constellation. Left Side Slide 25 Table of Contents so far! 1.Scientific Method 2.Adopt a Constellation 3.Constellation Notes 4.Create a Constellation
