  1. 2. The measurement of an object’s co-ordinates that tells the angle (clockwise) from north. (Sentence: The student read the book and it told him that the azimuth of Jupiter tonight would be 49 degrees from north, and so the student used his compass and faced in that direction)
  2. 4. Are a group of stars that create a pattern or shape in space; the group is given a name. (Sentence: The astronomer studied the constellations and found that the groups of stars matched the name of the picture they look like.)
  3. 5. A telescope that uses a convex lens in order to collect the light from a distant object and focus it to be viewed. (Sentence: The student studied the refracting telescope and noticed the convex lens at the front used to focus an object using the principle of refraction.)
  4. 9. Are celestial bodies that orbit a star to create a solar system (Sentence: Our solar system consists of 8 planets including our own, Earth)
  5. 11. A description that includes every object that is seen in space. (Sentence: The astronomer observed the many celestial bodies through his telescope and noticed that they seem to be revolving around Earth.)
  6. 15. A device that is used to measure the azimuth of an object. (Sentence: The astronomer used his compass and found the azimuth of the north star.)
  7. 16. Another name for ocular lens (Sentence: Through the ocular lens, the students observed the cell of a strawberry.)
  8. 18. The gravitational force/attraction between the celestial bodies that keeps the planets orbiting elliptically around the sun (otherwise, they would be out of orbit). (Sentence: The universal gravitation of the planets and other celestial bodies cause them to revolve in an elliptical shape around the sun.)
  9. 19. Another name for the sun-centered model. (Sentence: Due to technology advancements and space exploration, we now know that the solar system is actually heliocentric.)
  10. 20. Developed by Aristotle, this is a model of our solar system with Earth in the center, with other celestial bodies revolving around it. (Sentence: The Earth-Centered model of the solar system made sense since the astronomer was on Earth when he created it and so Earth was his Frame of Referene)

  1. 1. Another name for Aristotle’s Earth-Centered model. (Sentence: People at the time did not know that the geocentric model was incorrect due to their misled frame of reference.)
  2. 2. The co-ordinates used to locate objects in space, relative to Earth. These co-ordinates are the azimuth and altitude measurements. (Sentence: To find the location of the planet mars, the student followed the altitude-azimuth co-ordinates and found the planet.)
  3. 3. On a telescope, the lens the user puts their eye on to view a magnified object. (Sentence: The scientist looked through the ocular lens and saw the amoeba.)
  4. 6. A telescope that uses curved mirrors to collect and bring reflected light to a focal point for viewing. (Sentence: The student notice that in a reflecting telescope, the focal point is before the eyepiece so that it can be amplified by the ocular lens.)
  5. 7. Is the level of detail that a telescope can view a distant object. (Sentence: The student read the labels about the resolving power of the telescope before buying her own.)
  6. 8. The measurement of an object’s co-ordinates that tells the angle of an object above the horizon. (Sentence: Then the student read that the altitude of Jupiter was 68 degrees above the horizon and so he used his astrolabe and found Jupiter)
  7. 10. A point or set of points that is used to describe and find the relative positions of objects. (Sentence: The speed of the box on the truck depends on the frame of reference we are considering, whether it is truck (in which it would be 0km/h) or the ground (which would be the same speed as the truck.)
  8. 12. An oval shaped or shaped like a squashed circle, is the shape of a path a planet moves in around the sun (shape of the orbit). (Sentence: The planets do not revolve in a circle, but an ellipse shape due to the gravitation of the sun.)
  9. 13. Developed by Copernicus, this is a model of our solar system with the sun in the center, with other celestial bodies revolving around it. (Sentence: It was later discovered that the sun-centered model was actually the correct model, since the new frame of reference was the sun and the universe)
  10. 14. On a telescope, the big lens at the front used to magnify an object. (Sentence: The object was blurry, and so the scientist used a 40x objective lens to amplify the clarity and size of the specimen.)
  11. 17. A device that is used to measure an object’s altitude. (Sentence: The astronomer used his astrolabe and found the altitude of the north star.)
