Hi there! Have you ever helped with chores at home? One of my chores was vacuuming, and I always wondered about the powdery stuff that got sucked up. It turns out, that powdery stuff is called dust! Let’s learn more about it together.
Dust is everywhere! It’s so tiny and light that it can float in the air. Sometimes, you might see little specks of dust dancing in a sunbeam. Eventually, dust settles on things like fans or floors.
Dust is made of many different things. Some of it comes from outside, like tiny bits of sand and dried mud. When we play outside, these bits can stick to our shoes and clothes and come inside with us.
But dust isn’t just from outside. It also comes from inside our homes. Have you ever noticed a hole in your sock? Tiny bits of fabric from clothes, carpets, and furniture can break off and become dust. Even crumbs from food and tiny pieces of paper can turn into dust.
Did you know that our bodies make dust too? We all shed tiny bits of skin every day, and these can become part of the dust in our homes. If you have pets, their fur and skin flakes can add to the dust as well.
Dust is special because it tells a story about the place it comes from. Scientists can study dust to learn about different places. For example, dust from a city is different from dust in the countryside. By looking at dust, scientists can even guess if someone has a pet!
Dust from nature is unique too. Dust from the Sahara Desert in Africa is made of tiny bits of rocks, plants, and animals. This dust can travel far, reaching places like rainforests in South America and mountains in Europe. Even outer space has its own dust, made from exploding stars!
So, dust is made of tiny bits of everything around us, both inside and outside. It’s unique to each place, making the dust in your home one of a kind. Isn’t that amazing?
Thanks for learning about dust with me! Stay curious, and keep exploring the world around you. There are so many mysteries to discover!
Dust Detective: Become a dust detective in your own home! With a magnifying glass, explore different areas like the windowsill, under the bed, or on top of shelves. What do you see? Can you find different types of dust? Try to guess where each type of dust might have come from. Is it from outside, like sand, or from inside, like tiny fabric pieces?
Dust Art: Create a dust art project! Collect a small amount of dust from different places in your home using a piece of tape. Stick the tape onto a piece of paper to make a collage. Look closely at your dust collection. Can you see different colors or textures? Share your dust art with your family and explain what you discovered about where the dust might have come from.
Dust Diary: Keep a dust diary for a week. Each day, write down where you find dust in your home and what you think it’s made of. At the end of the week, look back at your diary. Do you notice any patterns? Is there more dust in certain places? Discuss with your family why you think dust collects more in some areas than others.
Sure! Here’s a sanitized version of the transcript:

(phone ringing)(chiming sound effect) – Hey, it’s Esther. Do you help with any chores? One of my chores growing up was vacuuming. Sometimes I’d look at everything that got sucked up and wonder, what is that? There was all this powdery stuff. I didn’t see it while I was vacuuming, but there it was. Where did it come from? Someone named Deago has a question about something we clean. Let’s give Deago a call now. (phone ringing)(chiming sound effect) – Hi, Esther. – Hey, Deago. – I have a question. What is dust? – That’s a great question. Where I live, I often find dust on my ceiling fan. It’s a layer of powdery, fuzzy stuff that I can sweep up with my fingers. Maybe you’ve noticed dust like that too. And you may have guessed that the powdery stuff in my vacuum was also dust. It seems like dust gets everywhere. That’s because dust is small enough and light enough to float around in the air. Sometimes, you can even see specks of dust drifting by. Eventually, the dust settles someplace like on my fan or the floor.
Now, here’s a view of dust you may not have seen before. This is dust up close. Look at that. Pieces of dust have different shapes. Some are round, some are crinkly, some are long and skinny. It makes me think maybe dust could be a lot of different things, but what and where does it come from? Before I go on, I’m curious, what do you think? Where does dust come from? Now would be a good time to pause the video and discuss.
Okay, you ready? I don’t know how you answered, but maybe you said dust is dirt. It’s bits of stuff from outside that get inside, and you’re right. That’s part of the answer. Dust includes tiny bits of sand, dried mud, and other things from outdoors. If you’ve ever played in the sand or had fun in the mud, you can probably guess how bits of outside stuff get inside. They come in on our shoes, clothes, and bodies. While some get washed away, other tiny bits fall or float off and join the dust inside.
Now, I’m not saying you should never get dirty outside. It’s awesome. But even if you did, outside stuff would probably still get inside. The wind can blow bits of sand and other outside stuff in through windows and gaps around doors. Plus, dust isn’t just stuff from outside. There’s more. Remember that close-up picture of dust? There were so many shapes, like this one. It looks kind of like a string or thread, right? Well, it is. This piece of dust came from something like a T-shirt or a towel. It’s a tiny bit of fabric. You might have noticed that things made of fabric can wear down, like when a sock gets a hole. Maybe you wondered where that fabric went. As you move around, tiny bits of fabric break off from your socks and other clothes, as well as the carpet and furniture. Those bits of fabric can become dust.
And have you ever eaten something that broke apart and made lots of crumbs? You probably notice those crumbs, but you might not notice the bits of paper that break off as you read a book, or the specks of black soot when you blow out a candle. Yet, those bits of food and paper and soot can all become dust. In fact, tiny bits of everything around you become dust. Even your body makes dust. Bits of skin come off your body in flakes. You might be able to spot some on your clothes, but even if you don’t see them, every one of us sheds millions of tiny bits of skin each day, really. Some of those skin flakes go down the drain, but a lot of them, you guessed it, become dust. If you have pets, flakes of their skin, fur, and dried saliva become dust too.
Hey, it’s just something bodies do naturally. So, that powdery fuzzy dust you see is actually bits of sand and other stuff from outside, and bits of fabric, food, and other things around you inside, and flakes of skin from your body. All of that added together is what indoor dust is made of. When I think about the dust in my home, I’m sure there’s bits of dirt from my garden outside. There’s probably fuzz from my favorite sweater. And I’m always sweeping up fur from my cats and crumbs from their food. The dust in my home is tiny bits of all the things around me. And the dust in your classroom comes from a different combination of things.
Because dust is tiny bits of all of the things that make up a place, scientists have discovered they can learn a lot from dust. Homes that are in the city have dust that’s different from homes that are in the country. By studying a sample of indoor dust, they can figure out where in the United States someone lives. They can also tell pretty well if someone lives with a dog or a cat. Dust is full of clues. It’s tiny bits of things that make each place unique. That’s true for dust in nature too. Dust from the Sahara Desert in Africa is tiny bits of the rocks, plants, and animals found there today and in the past. Scientists can track that unique dust from the Sahara as it blows to other places, like rainforests in South America and mountains in Europe. Even outer space has its own unique dust. Space dust includes tiny bits of exploding stars. Isn’t that incredible?
So, in summary, dust is tiny bits of the different things that make up a place. It’s tiny bits of what’s outside and what’s inside. And since the combination is unique to each place, that makes the dust where you live one of a kind. That’s all for this week’s question. Thanks, Deago, for asking it. Now, for our next episode, we reached into our question jar and picked out three questions sent into us that we’re thinking about answering next. When this video’s done playing, you get to vote on one. You can choose from, how do light bulbs work? Why do we sneeze? How are skateboards invented? So, submit your vote when the video’s over. We want to hear from all of you watching. There are mysteries all around us. Stay curious and see you next week.
