Hey! What's matter? No, no not what's the matter? Obviously since you are here with me you are pretty awesome at the moment. You might have heard that everything is made of matter. And that's true. You, soccer balls, i-pads even your pet, Fluffy all made of matters. 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 have 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 does not look all the same. Well that's because matter comes in different forms or states. Liquids are the state of matter that I am sure you are familiar with. If you've ever poured yourself a drink, while trying to watch T.V you might have noticed, that liquids take up space. Because, once the space inside your glass is full, direct 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 are removing water from it. Solids are matter too of-course. Probably the most obvious kind, rocks are solids and so is ice, which is just solid water. Soccer balls are solids, i-pads 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 that the space inside the box. Now, does air have weight? Let's try something else, take 2 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 the 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, # 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 them Sabrina said so.
