Study Guide Game

  1. 1. Study Guide Game<br />Chapter 4<br />
  2. 2. The Milky Way Galaxy is an example of:<br />Spiral Galaxy<br />Elliptical Galaxy<br />Spherical Galaxy<br />Irregular Galaxy<br />The Answer is : A. Spiral Galaxy<br />
  3. 3. Astronomers use parallax to measure a star’s:<br />Brightness seen from Earth<br />Distance from Earth<br />Color as observed from Earth<br />Color observed from Earth<br />The Answer is: B. Distance from Earth<br />Remember the demonstrations we did in class. This was to illustrate how astronomers use different perspectives to measure how far a star is away from Earth.<br />
  4. 4. True or False: Convection is the process of converting hydrogen into helium.<br />True<br />False<br />The Answer is: B. False<br />FUSION, people! FUSION! Convection is the process which the energy is heated and then cooled. As it is heated it becomes less dense and escapes to the outer atmosphere of the sun.<br />
  5. 5. Which of the following objects is part of a low-mass star’s life cycle?<br />White dwarf<br />Super Giant Star<br />Black Hole<br />Neutron Star<br />The Answer is: A. White Dwarf<br />High-mass stars have two different outcomes- neutron star and black hole. <br />Super giant= high mass. Giant star= low mass<br />
  6. 6. True or False: The more sunspots there are, the warmer Earth will be.<br />True<br />False<br />The Answer is: B. False<br />The more sunspots there are the cooler Earth is. Sunspots are dim areas on the sun which decreases the amount of energy being sent to Earth.<br />
  7. 7. What factor determines the length of a star’s life cycle?<br />Density<br />Size<br />Brightness<br />Mass<br />The Answer is: D. Mass<br />Remember we classify stars by their mass. Low-mass stars and high-mass stars!<br />
  8. 8. True or False: The Sun’s chromosphere is the layer of the sun which we only see during a total solar eclipse.<br />True<br />False<br />The Answer is: B. False<br />Remember, the layer of the sun we can not see is the corona. The density of this layer is too light for us to see. <br />
  9. 9. What do scientists use to note the existence of a black holes?<br />The Electromagnetic Spectrum<br />The Doppler Effect<br />X-Ray<br />Parallax<br />The Answer is: C. X-Ray<br />Remember: As the black hole’s gravity takes in all the surrounding matter, it heats up and emits x-rays.<br />
  10. 10. Sunspots appear on the surface of the sun in a regular pattern of:<br />1 year<br />11 years<br />11 months<br />1 month<br />The Answer is: B. 11 years<br />Remember the homework. You graphed the sunspots in 1 year increments but it was every 11 years that the number of sunspots increased!<br />
  11. 11. Which of the following is NOT a way energy moves through the layers of the sun?<br />Convection<br />Fusion<br />Friction<br />Radiation<br />The Answer is: C. Friction<br />I never even mentioned friction in this entire lesson. DO NOT PICK friction for ANY answers on the test!<br />
  12. 12. Draw the life cycle of a low-mass star using the following key words.<br />White dwarf<br />Main Sequence<br />Giant Star<br />Nebula<br />Bonus point for adding Planetary Nebula.<br />You will need to be able to identify the different phases of BOTH high-mass and low-mass stars. Study your Venn Diagram!<br />
  13. 13. Study tips:<br />Use your pre-assessment test, homework and exit slips<br />The power points will be essential but know the concepts!<br />When asked to explain or describe:<br />Full credit= more than three sentences or bullet points which directly answer the question!<br />Please email me if you have any questions about the material or test.<br /><br />
