11 What determines a star’s life cycle?
Star Life Cycles What determines a star’s life cycle? What happens to the elements a star fuses in its core as it gets older? Which type of star explodes in a super nova?

12 Are We Made of Star Stuff?
Think-Pair-Share

13 We are made of the stuff a star makes in its core
Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy. Where does all of the elements we see here come from? You, me, all other life, the planets –rocks, gasses, and everything we see in the universe comes from the fusion and supernova explosions of a star. One of the most profound things I have ever learned is that not only are we a part of this universe, but the universe is also a part of us.

16 Star Notes Pg 24 A star produces energy and light by nuclear fusion
The Star’s core combines hydrogen atoms to form helium which releases energy and light. Scientists classify stars using 5 different criteria Brightness (Luminosity) Size- Means mass, which determines life cycle Temperature- This determines a star’s color, measured in Kelvin (K) Composition- What elements a star is fusing Color- Blue, white, yellow, orange, red.

Vocabulary terms you may need to know: Radius- Length from the center of a circle to the outside or half a diameter Luminosity- The brightness of an object that gives off light Temperature- Measured in Kelvin (K) F = 0 C = K Mass- How much matter (atoms/stuff) something has

36 Constellation Close Read
Complete the close read about constellation and answer the questions in complete sentences

37 Ursa Major The Hunt The Micmac Indians of Nova Scotia and the Iroquois Indians along the St. Lawrence seaway share one story about the Big Bear. In this story, the quadrangle of the dipper represents a bear that is pursued by seven hunters; the three closest hunters are the handle of the dipper. As autumn approaches, the four farthest hunters dip below the horizon and abandon the hunt, leaving the closest three hunters to chase the bear. The hunters are all named after birds. The closest hunter to the bear is named Robin, the second closest is Chickadee, and the third is Moose Bird. Chickadee is carrying the pot in which the bear will be cooked. The second star in the handle is actually two stars [the famous double star system] called Mizar and Alcor which represent Chickadee and the pot. In autumn, as the bear attempts to stand up on two legs, Robin wounds the bear with an arrow. The wounded bear sprays blood on Robin, who shakes himself off and in the process, colors the leaves of the forest red; some blood stains Robin and he is henceforth called Robin Redbreast. The bear is eaten, and the skeleton remains traveling through the sky on its back during winter. During the following spring a new bear leaves the den and the eternal hunt resumes once more.

38 Make your own constellations
Constellations myths and culture ( read a constellation myth ) How does it represent the culture’s beliefs about the cosmos? Draw your own constellation. Give your constellation a name. Write a one paragraph story about your constellation. What is the purpose of constellation stories?

39 T-P-S “Where are the stars in orion”
Orion is a constellation- a group of stars in the sky. Choose the statement you think best describes the stars in Orion. AND EXPLAIN YOUR THINKING The stars of Orion are close together in space The stars in Orion orbit the Sun, just like planets The brightest stars in Orion are the ones that are closest to us. You can’t tell if the brightest stars in Orion are really brighter than the others, or if they are just closer to us. The stars in Orion are all the same distance from us. That is why we see the shape of the constellation The stars are arranged in the constellation Orion for only part of the year. The rest of the year they change their pattern and form different constellations

40 Constellations Even though the stars in constellations looks close together, they are actually very far apart As the Earth rotates on its axis and revolves around the sun, our perspective of the night sky changes. Look at orion

41 Source: NASA StarChild

42 There are two types of constellations
Seasonal- Because Earth is revolving around the Sun, out position in space changes- giving us a different view of space. Circumpolar- “around the poles”- these constellations are positioned in space where we can see them all year long. They are positioned around the North Star (Polaris)

43 Why do we see different constellations during the evening?
Earth rotates on its axis. Rotation - When a planet or moon turns all the way around or spins on its axis one time.

44 Why do we see different constellations during the evening?
The Earth revolves around the Sun. Revolution - The circling of one object around another object in space. The Earth revolves around the Sun. 

45 Constellations used for navigation.
The Big Dipper helps find direction. Runaway slaves used the Big Dipper (Drinking Gourd). Follow the Drinking Gourd.

47 Test Review What characteristics are used to classify stars?
How can you determine which of two stars is older by using color? How does a stars mass determine its life cycle? Write the colors of stars from hottest to coldest? If a star has a temperature of 8,000 C then what color would it be? What are the different types of stars? Where would each type of star and color be located on an Hertzsprung-Russel Diagram? DRAW What is fusion? How and where does a star produce energy and light? As a star gets older what happens to the elements it fuses? What is the life cycle of a low mass star? What type of star is our sun, and what part of it’s life cycle is it in? Explain.

86 Constellation Confusion/ Project

87 Do Now Name __________ Illumination 19% As an observer, the flash lights seems brighter or dimmer depending on the distance you observe the light from. The further away you are the dimmer the light will appear. However, if you were to observe the light emitted by the three flashlights from the same distance, would one light appear brighter than another? Explain. Astronomers must calculate a stars distance in order to calculate its ACTUAL brightness, because from Earth it may APPEAR brighter or dimmer depending on how far away it is.
