Vídeo de preguntas y respuestas

  • Why is Earth and Space Science important?

    It helps answer fundamental questions about our universe and the Earth's position within it.

  • What topics are covered in this course?

    The course covers seasons, solar and lunar eclipses, the water cycle, the rock cycle, plate tectonics, and environmental impacts.

  • How does this course impact learners?

    It empowers learners to understand key scientific concepts and encourages them to make positive changes for the Earth.

  • Can we still walk from the US to Africa?

    No, due to plate tectonics, the continents have drifted apart, making such a walk impossible now.

  • Is the water we drink the same as that in the past?

    Yes, the water cycle means the same water has been used by different life forms throughout Earth's history.

    - Hi everyone.
  • 00:00:01
    Sal Khan here and I'm with Iman Howard, who is our manager
  • 00:00:05
    for all of our stem content on Khan Academy.
  • 00:00:07
    And we wanted to welcome you
  • 00:00:08
    to the Middle school Earth and Space Sciences course.
  • 00:00:13
    Iman, why should folks be excited about this?
  • 00:00:17
    - So Middle school Earth and Space Science
  • 00:00:19
    is really exciting
  • 00:00:21
    because it's one of those areas
  • 00:00:22
    of science that answers what's happening in our universe.
  • 00:00:26
    And then like when you dig in, you're like
  • 00:00:28
    "What is happening in our universe?
  • 00:00:30
    This is why we have seasons."
  • 00:00:32
    And so we start like really big, we go all the way
  • 00:00:36
    to outer space and we figure out sort of earth's position
  • 00:00:39
    in our solar system and the relationship
  • 00:00:41
    to gravity and our inner planets and our outer planets.
  • 00:00:45
    And then we keep digging in and we finally figure
  • 00:00:48
    out how Earth's position answers seasons.
  • 00:00:50
    It's not because we get closer to the sun
  • 00:00:52
    or how based on earth's position, we look up at the moon
  • 00:00:56
    and you'll see a lunar eclipse or how you don't look up
  • 00:00:59
    and look at a solar eclipse, like seriously
  • 00:01:02
    don't look up because it'll hurt your corneas.
  • 00:01:05
    And then we keep going and we talk about water
  • 00:01:08
    and how the same water that you're drinking right
  • 00:01:10
    now is the exact same water that dinosaurs drink.
  • 00:01:14
    And then we get into the rock cycle and we figure
  • 00:01:17
    out why mountains are here and how we're moving right now.
  • 00:01:22
    Literally the plates below us are moving and how
  • 00:01:25
    at one point we could walk across all the way from the US
  • 00:01:29
    to Africa and how plate tectonics really changed that.
  • 00:01:32
    And then finally, finally, we talk about us.
  • 00:01:36
    We talk about us on this planet
  • 00:01:38
    and how there's so many amazing resources here and how well
  • 00:01:43
    how we use them really impacts the earth
  • 00:01:45
    and how that could impact our climate.
  • 00:01:47
    And really awesome things that you can do
  • 00:01:48
    as a learner to change all that
  • 00:01:50
    and make this earth really awesome.
  • 00:01:53
    What are you excited about, Sal?
  • 00:01:55
    - Well, I'll just double down everything you said
  • 00:01:57
    and I like how you said we're gonna dig into it
  • 00:01:59
    'cause it's very appropriate pun for earth, earth and space.
  • 00:02:02
    This starts to answer the questions of,
  • 00:02:05
    the from the cosmos to earth.
  • 00:02:08
    Over billions of years, as you mentioned, the earth is alive
  • 00:02:12
    in certain ways with the plates are still moving
  • 00:02:14
    it's active and we should say at least, and you know
  • 00:02:17
    we are part of the earth.
  • 00:02:18
    Your point, the, the water in our bodies
  • 00:02:20
    the air that we breathe, it's the same water
  • 00:02:23
    and earth that has been been here and the air
  • 00:02:25
    for billions and billions of years.
  • 00:02:27
    So to be able to actually understand that it,
  • 00:02:29
    it actually gives me, gives me goosebumps.
  • 00:02:32
    So I think folks will be very excited about this course.
  • 00:02:34
    - Absolutely.
  • 00:02:35
