  1. Hello Friends.
  2. Today we are going to be exploring our maps and
  3. globes if you remember correctly a map is a piece
  4. of paper showing us something.
  5. It is two dimensional and our globe is our spa
  6. fears. It is three dimensional.
  7. We can put our hands on it, spin it and
  8. look all around our globe.
  9. So we're going to learn about some different parts of
  10. our maps and our globes.
  11. Here is a map and let's look and see what
  12. we see.
  13. I see different places on this map.
  14. I see the top and bottom are white.
  15. I see some lines.
  16. So let's learn about some of these things.
  17. So first a country a country is a nation with
  18. its own government.
  19. We live in the country of the United States of
  20. America but that's not the only country in the world.
  21. Even in this picture of the United States, you can
  22. see Canada on top the United States in the middle
  23. and Mexico, right down below us.
  24. You can have a map or a globe showing anything
  25. the globe shows the entire world.
  26. So you can see all of the countries that exist
  27. on our earth right here.
  28. This is two dimensional, but it looks like a three
  29. D. Globe and you can see that china is outlined.
  30. You can also see china on this map.
  31. Right here we see china and africa and Australia, and
  32. so many different countries and continents.
  33. Another thing that we can find on our globe is
  34. the equator.
  35. So the equator is an imaginary line that goes all
  36. around our earth.
  37. At the very center at the widest part on this
  38. globe, you can see it as the dark blue line
  39. that goes all the way around the globe.
  40. And you can see it a little bit better.
  41. In this picture, it splits our globe in half.
  42. It has a top half and bottom half.
  43. And these are called our hemispheres.
  44. We have our northern hemisphere up top above the equator
  45. and we have our southern hemisphere down there below our
  46. equator. Another thing that we can observe on our maps
  47. and globes are lines of latitude and longitude.
  48. Earlier I said we saw lines on those maps.
  49. Can you see those lines, do you see those lines
  50. that are going up and down?
  51. And those lines that are going across?
  52. Here's our picture of the United States again.
  53. Do you see all those lines?
  54. Those are our lines of latitude and longitude.
  55. The lines of longitude are lines that go up and
  56. down. And I remember this by saying longitude longitude.
  57. These are the long lines that go up and down,
  58. longitude. Lines go up and down.
  59. You can see it on this picture.
  60. So those lines that go all the way from the
  61. top, All the way to the bottom are the lines
  62. of longitude.
  63. Our lines that go around the globe are called latitude.
  64. Our lines of latitude go around the globe.
  65. I remember this by saying latitude flat itude.
  66. These are the flat lines that go all around our
  67. earth. So our lines of latitude include the equator.
  68. These go around our earth.
  69. Our lines of longitude also have one called the prime
  70. meridian. This is a lot like the equator, but it
  71. goes up and down, splitting our earth into the eastern
  72. hemisphere and the western hemisphere.
  73. These help us tell where something is.
  74. If I tell you that something is at the intersection
  75. of this line of latitude and this line of longitude,
  76. you can tell me exactly where it is, what it
  77. is. We can also see the north and south poles
  78. on a map or a globe.
  79. You can see right here at the tip top of
  80. our earth is the north pole and at the bottom
  81. is the south pole.
  82. This is what our earth rotates on and it is
  83. also called the axis.
  84. There are so many more things that you can observe
  85. on a map or a globe that we're going to
  86. dive into while we're learning about this.
  87. So next time you see a map or a globe,
  88. I want you to pay attention to these things.
  89. I don't want you to just look at the picture
  90. on the map.
  91. I want you to look at the lines of longitude
  92. and the lines of latitude.
  93. I want you to look at it and tell me
  94. is it in the northern hemisphere or is it in
  95. the southern hemisphere?
  96. Is it in the eastern hemisphere?
  97. Or is it in the western hemisphere?
  98. These are all things that you can see on the
  99. map now.
  100. So next, what I want you to do is go
  101. to back to our google classroom and do the independent
  102. activity that I have loaded.
  103. If you have any questions, please feel free to send
  104. me a message.
  105. Or you can, of course, come back and watch this
  106. video.
