What’s Matter? – Crash Course Kids #3.1

Theme Music Hey! What’s matter? No, no! Not what’s the matter. Obviously
since you’re here with me you’re pretty awesome at the moment. You might have heard that everything is made of matter–and that’s true. You, soccer balls, iPads–even your pet Fluffy:
all made of matter. So…that’s interesting. But what is matter exactly? The scientific answer is matter is
anything that has weight and takes up space. You already know about weight, right?
That’s just how heavy something is. Like if you’ve ever been to a doctor’s office, the first thing they do is have you
stand on the scale so they can measure how much you weigh. As for taking up space, another way of
thinking about it is that all matter has volume it simply fills the area it’s in. When
you pour water into a glass, for example, the water’s volume is the amount of space
that it takes up in the glass. So all matter has volume and weight, but
it sure doesn’t all look the same. Well that’s because matter comes in
different forms or states. Liquids are a state of matter that I’m sure you’re
familiar with. If you’ve ever poured yourself a drink while trying to watch
TV, you might have noticed that liquids take up space because once the space
inside your glasses full…gaaa! Right on the carpet. Sorry mom. You also know that water has
weight if you carry a water bottle. As you drink from it it gets lighter
because you’re removing water from it. Solids are matter too, of course. probably the most obvious kind. Rocks are solid and so is ice–which is just solid water. Soccer balls are solid. iPads, your
pet Fluffy, and every single guy in One Direction. And just like rocks, all those things have weight and take up
space. Now you know what’s weird? Sometimes matter can’t be seen or felt, but it’s there. Like the air we breathe. Air is an example of gas the third main state of matter. And I
probably know what you’re thinking. How do we know air, or any gas really, is
there if we can’t see it. Well, we can prove it
by doing an experiment. Science! Let’s start by asking the question: Is
air matter? Because if it is, it should take up space and have weight, right? To
see if air takes up space, look it. I can easily drop an empty
balloon into this little box, but a full one won’t fit. That’s because the air that fills the
space inside the balloon is bigger than the space inside the box. Now, does air have weight? Let’s try
something else. Take two empty balloons and tape them to
the ends of a meter stick. Then we’ll hang the meter stick on a
string so that it’s perfectly balanced. Now let’s see what happens if we blow up
just one of the balloons and put it back on our meter stick. Check it out! The end with the full balloon sinks–it
weighs more than the empty balloon because the air gives it extra weight. The balloon full of air will always weigh
more than the empty one because air is matter and matter has
weight and takes up space whether it’s a liquid, a solid or a gas. So listen: the next time someone tells you that something doesn’t matter, you can
tell them, to their face, that technically everything is matter. And tell him

  1. i dont get it if air has weight, why when u drop a balloon with air it takes a longer time to fall down than the empty balloon

  2. Thanks I have a science test tomorrow 🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗

  3. One exception to the "everything is matter" thing. Neither heat nor light is matter. No shade, just clearing that up 🙂

  4. no! it is supposed to be mass not weight. Weight is the pressure on the object or how 'Heavy' something is. Weight is usually measured in Newtons. Mass, on the other hand, is usually measured in Kilograms.
    She used weight in 0:35

    Thanks! !!!

  6. Now I know what does volume mean. I'm from Estonia and I'm in 3rd grade. That's when I'm 10 years old.

  7. ye ye bruv real good ye gonna learn heaps of sick rhymes ye aye gonna be doing features with stormzy ye bruv

  8. Wow helped a lot on my Homework! i subscribed i think you should keep it up on your Chanel.
    can you give me tips for my own Chanel people give a like on the vid like i did

  9. if you legitimately said "well technically, everything is matter" when someone says "it doesn't matter" I think everyone would think you are a massive nerd
