  1. I that today we're gonna look up states of matter
  2. and how states of matter affect resistance.
  3. This bottle is a prime example.
  4. The ass of the bottle is solid.
  5. Therefore, the state of matter is solid.
  6. It's plastic.
  7. The inside of the bottle contains water that we can
  8. see that is the liquid within that.
  9. But also there's something you can't see, which is that's
  10. a Gus.
  11. That's its state of matter.
  12. So if you're thinking about these sorts of things you're
  13. thinking about, kind off tiny, tiny, tiny, tiny particles.
  14. Now, this plastic I wouldn't be able to move through.
  15. The particles are too closely packed, and therefore I'd be
  16. unable to move through them.
  17. Anyone that's gone swimming or seen a boat knows that
  18. we can move three water.
  19. It causes less resistance against our movements than a solid
  20. object would.
  21. We can't run into a brick wall, but we can
  22. swim through water just as I can.
  23. Walk along the road through air is actively in order
  24. to move faster through the EC, we need to be
  25. able to streamline or create a steam, streamlined body shape
  26. or home jet shape.
  27. This is why often people do cycling or something similar?
  28. Well, we're clothing that isn't Maggie.
  29. It's streamlined.
  30. Therefore, won't pull them back and create more air resistance.
  31. The same is a rocket is designed to make sure,
  32. but it rather than resists the air.
  33. It cuts through it.
  34. Oh, a speedboat, The bottom of which will be really,
  35. really, really ridged with very, very sharp edges.
  36. The sharp edges effectively cut through the water, making it
  37. much easier for the objects to flow through.
  38. If you had a speedboat with exactly the same power,
  39. one of which didn't have a ridged a streamlined base
  40. on one of which did, if you exactly the same
  41. force early, the speedboat bottom that was streamlined would go
  42. fast on.
  43. The one that wasn't would go slower, even though the
  44. same force, the push from the engine is exerted with
  45. the same force and therefore should be the same speed
  46. as Primary seven.
  47. Today you're going to design your own experiment to look
  48. at streamlining.
  49. That is to say, you can do a number of
  50. things. You could create a plastic bottle rocket by using
  51. a long, large, empty plastic bottle, creating some form of
  52. rocket to stick to the top of it and then
  53. squashing your bottle on letting the rocket fly away.
  54. You could potentially think about the streamlining of a boat
  55. using again another bottle or carton or something similar you
  56. found in your house, preferably empty.
  57. Cut out the bottom of it.
  58. Create the hull of the tapes and think about different
  59. ways. You can change the base of the vote to
  60. make a more streamlined effect.
  61. May be using tinfoil law.
  62. Kalinda. Fill whatever you can find at home.
  63. Think about his idea that you're cutting through the water
  64. well. Finally, what you could do is use a plastic
  65. bottle or another cartoon that is waterproof and fill it
  66. with a few rocks or stones or something that's more
  67. dense and heavy than water along with some water, too.
  68. Then drop it to maybe the bottle of your sink.
  69. That's one of water or the bottom.
  70. Your bath, that sort of water in time.
  71. How long it pigs for it to reach the bottom,
  72. then do it the same thing again.
  73. But maybe add fins or a nose cone or something
  74. else to try and make your object more streamlined, as
  75. you do this on to make notes.
  76. No scientific findings hypothesize gas.
  77. Talk about what might make something more streamlined, less streamlined.
  78. You could also even look at paper aeroplanes and think
  79. about how to make the most streamlined paper aeroplane.
  80. Obviously, that wouldn't work so well going through water.
  81. But it would add to the idea of cutting through.
  82. I can't wait to see how you get on.
