  2. 5 Point Questions 1st question is for your # 4s

  3. # 1 Which color star has the most amount of energy? a) Red b) Orange c) White d) Blue

  4. # 1 Answer Which color star has the most amount of energy? a) Red b) Orange c) White d) Blue **Make sure you know WHY! *Blue waves are closer together, which means a short wavelength and higher frequency (which means MORE energy!) **Also remember we only SEE color (visible light) because the wavelengths are the perfect length to be seen and processed by our brains. All other types of electromagnetic radiation has wavelengths that are too long or short to be seen. # 3s…you’re up next

  5. # 2 What does color tell us about a star? • The star’s temperature • The star’s distance from Earth • The star’s age • The star’s size

  6. # 2 Answer What does color tell us about a star? • The star’s temperature • The star’s distance from Earth • The star’s age • The star’s size Color is a visual representation of temperature. ROYGBIV (coolest to hottest due to the amount of energy). # 1s or 5s…you’re up next

  7. # 3 What is a light year? • The time it takes light to travel in 1 year. • The time it takes to travel 1 astronomical unit. • The distance light travels in 1 year. • The distance of 1 AU.

  8. # 3 Answer What is a light year? • The time it takes light to travel in 1 year. • The time it takes to travel 1 astronomical unit. • The distance light travels in 1 year. • The distance of 1 AU. Light Years are used to measure distance between galaxies. AUs are better used for distances between planets in a solar (planetary system) and Parsecs are for larger, universal distances. *Make sure you know what this means for the size of our galaxy (old quiz). …how long it takes for light to travel across our galaxy. 2s…you’re up next

  9. # 4 What determines the path a star takes (Stellar Cycle—when it begins to die) • The shape of the star • The luminosity of the star • The size or mass of the star • The distance away from the sun

  10. # 4 Answer What determines the path a star takes (Stellar Cycle—when it begins to die) • The shape of the star • The luminosity of the star • The size or mass of the star (Small, Medium, and Massive stars all die differently) • The distance away from the sun **Large (and hot) stars have the shortest lifespan. You WILL need to know the life cycle of small, large, and massive stars. Beginning (nebula) to end… Next up….3s.

  11. #5 Question Which two Earth spheres are interacting if a lightning strike were to start a forest fire? • Atmosphere and biosphere • Biosphere and hydrosphere • Atmosphere and geosphere • Hydrosphere and biosphere

  12. #5 Answer Which two Earth spheres are interacting if a lightning strike were to start a forest fire? • Atmosphere and biosphere • Biosphere and hydrosphere • Atmosphere and geosphere • Hydrosphere and biosphere Next up 1s

  13. #6 Question • Amy wants to buy new tires for her bike. She wants to find out if the size of the wheels will affect how far she can coast on her bike. She is curious to see if the thickness of the tires affects how far she can coast. She decided to compare two brands of tires. She uses a small, thick tire and a large, thin tire. She designs an experiment with 5 trials per tire so it is accurate. She finds the large tire lets her coast longer. Is this a valid test? Why or why not?

  14. #6 Answer • Amy wants to buy new tires for her bike. She wants to find out if the size of the wheels will affect how far she can coast on her bike. She is curious to see if the thickness of the tires affects how far she can coast. She decided to compare two brands of tires. She uses a small, thick tire and a large, thin tire. She designs an experiment with 5 trials per tire so it is accurate. She finds the large tire lets her coast longer. Is this a valid test? Why or why not? • NOT VALID!!!!! TWO variables!!!! Size and Thickness of the tire are different on both tires. It is not possible to determine if size or thickness was the variable that affected coasting times. • Up nexts….2s

  15. #7 Question Two students are planning an experiment to determine the effect of the temperature on the number of cricket chirps per minute. They used two identical containers. What is the test (independent) variable and the outcome (dependant) variable in this experiment? • Test = # of crickets, Outcome = temperature • Test = containers, Outcome = temperature • Test = # of cricket chirps, Outcome = temperature • Test = temperature, Outcome = # of cricket chirps per minute

  16. #7 Answer Two students are planning an experiment to determine the effect of the temperature on the number of cricket chirps per minute. They used two identical containers. What is the test (independent) variable and the outcome (dependant) variable in this experiment? • Test = # of crickets, Outcome = temperature • Test = containers, Outcome = temperature • Test = # of cricket chirps, Outcome = temperature • Test = temperature, Outcome = # of cricket chirps per minute **Answer #4s up next

  18. #8 Answer According to Scientists who support the Big Bang Theory (Remember, theories are explanations, strongly supported by evidence that can be used to make predictions) believe the universe began • 4.6 BYA • 13.7 BYA **Answer • 49.6 BYA • 130 BYA 4.6 BYA is the proposed age of our solar system (nebular theory, which is the theory our SS formed from remnants of a dead massive star) ***Honors make sure to review question from old tests on evidence of the Big Bang.

  19. 10 Point Questions 1st question is for your # 3s

  20. # 1 What was Copernicus’ contribution to Astronomy?

  21. # 1 Answer What was Copernicus’ contribution to Astronomy? Copernicus was the scientist who first believed that the Sun was the center of the solar system, not the Earth AND that all the objects in our solar system revolve around the sun. Galileo also helped confirm this with his trusty telescope! **This is known as the heliocentric model. What did scientists believe before this? # 4s or 5s…you’re up next

  22. # 2 Describe our sun. Color, Temperature (not exact, just compare), Size, Stage of stellar evolution. *How does it get its energy?

  23. # 2 Answer Our sun is yellow (due to temperature!!!), Average temperature (between 5,000 and 6,000 degrees), it is a medium size star, and it is in its main-sequence stage (middle of its life) *It gets its energy from nuclear fusion in its core (fusing hydrogen to put out helium). # 1s…..you’re up next

  24. #3 The H-R Diagram shows the relationship between • Absolute and apparent magnitude • Parallax (distance) and temperature • Apparent magnitude and luminosity • Temperature and absolute magnitude

  25. #3 The H-R Diagram shows the relationship between • Absolute and apparent magnitude • Parallax (distance) and temperature • Apparent magnitude and luminosity • Temperature and absolute magnitude *Note--Absolute magnitude and luminosity are BOTH measures of TRUE brightness **Make SURE you can read this diagram. **Remember, stages in life are seen here too. • # 2s…..you’re up next

  26. #4 If two stars have the same surface temperature, BUT they appear to have a difference in brightness, what is a possible reason for this difference?

  27. #4 Answer If two stars have the same surface temperature, BUT they appear to have a difference in brightness, what is a possible reason for this difference? These stars are different DISTANCES from Earth OR they are different SIZES. # 3s…..you’re up next

  28. # 5 You have just witnessed a full moon. Which phase follows this in the days to come? • Waxing Gibbous • Waning Gibbous • Waxing Crescent • Waning Crescent

  29. # 5 Answer You have just witnessed a full moon. Which phase follows this in the days to come? • Waxing Gibbous • Waning Gibbous • Waxing Crescent • Waning Crescent # 2s or 5s you’re up!

  30. Make sure you can identify the moon’s phases based on the diagram below. *Where would eclipses occur? Can you relate tides to these phases?

  31. #6 The visible surface of the sun is called the • Chromosphere • Corona • Photosphere • Core

  32. #6 Answer The visible surface of the sun is called the • Chromosphere-Layer along with the corona that make up the atmosphere of the sun, can be seen during an eclipse. • Corona-can be seen during an eclipse along with the chromosphere • Photosphere • Core-where nuclear fusion is occuring *Number 2s

  33. # 7 What is true about the relative distance between the planets? • The terrestrial planets are relatively close together • The gas giants are relatively close together • The terrestrial planets are relatively close together, and the gas giants are further apart. • The gas giants are relatively far apart and so are the terrestrial planets.

  34. # 7 Answer What is true about the relative distance between the planets? • The terrestrial planets are relatively close together • The gas giants are relatively close together • The terrestrial planets are relatively close together, and the gas giants are further apart. **Remember Kepler’s Laws though! The further away from the sun, gravity decreases and revolution increases. • The gas giants are relatively far apart and so are the terrestrial planets. # 3s…..you’re up next

  35. #8 Draw a picture showing the POSITIONING of the moon during a New Moon phase (you must include the moon, earth, and sun)

  36. #8 Answer Draw a picture showing the POSITIONING of the moon during a New Moon phase (you must include the moon, earth, and sun) Earth Moon Sun Give board to your choice #

  37. # 9 The last question—New moon would result in the GREATEST or LEAST Tidal Range---WHICH means we would see WHICH Type of TIDE?

  38. # 6 answer The last question—New moon would result in the GREATEST or LEAST Tidal Range---WHICH means we would see WHICH Type of TIDE? GREATEST tidal range (greatest difference between high and low tides) THIS IS A SPRING TIDE! **Know NEAP too!

  39. 20 Point Questions 1st Question is for your 1s

  40. # 1 How do the orbital paths of objects in the solar system differ?

  41. # 1 answer How do the orbital paths of objects in the solar system differ? • Not every object takes the same path around the sun---all Planets travel (in ellipses) on one plane---the moon travels around the earth in another plane (a different tilt) Next question is for # 4s

  42. # 2 In the night sky, there appears to be a VERY bright object. When you look closely with a telescope (thanks to Galileo), you notice there are actually TWO stars. This is called a __________________. Together, describe the absolute magnitude of EACH star, compared to the apparent magnitude of the two together.

  43. # 2 Answer In the night sky, there appears to be a VERY bright object. When you look closely with a telescope (thanks to Galileo), you notice there are actually TWO stars. This is called a Binary Star System or MULTIPLE Star system. Together, describe the absolute magnitude of EACH star, compared to the apparent magnitude of the two together. The absolute magnitude of each star is less than the total absolute magnitude of the system. Together, they appear very bright, but in fact they are dimmer on their own. # 3s you’re up next

  44. # 3 Why do we only ever see the same side of the moon?

  45. # 3 Answer The moon is rotating and revolving at the same rate (every 27.3 days). Because the sun’s light reflects off the surface of the moon, we only see the side that is facing us (earth). # 2s…you’re up next

  46. # 4 Describe some of the characteristics of the sun that show it is quite an active star!

  47. # 4 Answer Describe some of the characteristics of the sun that show it is quite an active star! Sun spots—dark patches with a lower temperature than its surroundings. *Galileo watched these to prove the sun rotates on its axis. Prominences—Arcs of gas with the potential to turn into a flare. Solar Flare-Explosive events which can drastically affect our magnetic field (bye bye technology!) # 4s…you’re up next

  48. # 5 What causes the phases of the moon?

  49. # 5 Answer What causes the phases of the moon? The moon reflects the light of the sun. Depending on where the moon is in its orbit, we see different amounts of this reflected light. # 2s or 5s you’re up next

  50. # 6 Look at the HR diagram. Describe the stars at letters B and C.
