  2. Astronomers & Theories

  3. These are the Latin words for sun and moon

  4. The movement of the Earth about the Sun

  5. This theory, elucidated by Ptolemy, places the Earth at the center of the universe

  6. This famed scientist determined the two factors that keep the planets in orbit

  7. This astronomer showed that the orbit of each planet is an ellipse.

  8. Astronomers & Theories

  9. This theory states that the planets revolve around the sun

  10. Most astronomers from this region believed that the universe is perfect and unchangeable

  11. He was the first scientist to use a telescope to look at objects in the sky

  12. This Polish astronomer believed in the heliocentric system  

  13. This metal-nosed man observed the position of planets, providing data later studied by Kepler

  14. Light

  15. Orange wavelengths of light are reflected off of this

  16. These are the primary colors of light

  17. These substances are used to color paints or other materials

  18. These two colors are additively mixed to give yellow

  19. This term describes any two colors that are combined to make white light

  20. Light

  21. The appearance of water ahead on the road on a summer day

  22. This occurs when light rays hit a bumpy or uneven surface.

  23. The bending of light waves they enter a different medium

  24. The definitions of transparent, opaque, & translucent

  25. This mirror forms virtual or real images

  26. Earth, Moon, & Sun

  27. The main force that changes the tides

  28. This movement causes day and night.

  29. The phase of the moon during a lunar eclipse

  30. The reasons for the seasons

  31. The darkest part of the shadow of an eclipse

  32. Earth, Moon, & Sun

  33. This term describes the lighter, larger part of an eclipse’s shadow

  34. This tide occurs when the moon is at a 90 degree angle from the earth

  35. Areas of cooler gas in the photosphere

  36. A tide with the greatest difference between low and high tide

  37. These are huge looping explosions of gas through the chromosphere

  38. Seeing is Believing

  39. A person who can see objects far away but close objects are blurry  

  40. The part of the eye that looks black

  41. This uses lenses or mirrors to collect and focus light from distant objects

  42. The colored muscle in the eye

  43. This type of lens produces a virtual image

  44. Seeing is Believing

  45. This uses lenses to focus light and record an image of an object

  46. A short, thick nerve that sends signals generated within the retina to the brain

  47. This lens is thicker in the center then at the edge

  48. The clear lens that protects the eyes from dust

  49. This term refers to how light waves in a laser beam all matchcrest with crest,trough with trough

  50. It’s a Big, Big, Big, Big World!
