Hello, friends! Have you ever flown a kite and noticed it needs wind to stay up in the sky? That’s because it uses wind energy! But what exactly is energy? Energy is what makes things move or happen. There are many types of energy, like light, heat, electricity, water, and wind energy. Today, we’re going to learn about wind energy, which is a special kind of energy you can’t see, but you can feel it all around you!
Wind energy is the power we get from the wind. Even though you can’t see it, wind energy can do amazing things. It can make flags wave, help kites fly high, and even push toy boats across a pond. Have you ever played with a pinwheel? When you blow on it, you’re using wind energy to make it spin!
Here’s a fun experiment you can try at home to see wind energy in action. You’ll need a fan and some small objects like a dollar bill, an empty water bottle, a pen, a plastic egg, and a hammer. Place these objects in front of the fan and turn it on. Which object do you think will move first?
As the fan blows, you’ll see the lighter objects like the dollar bill and the water bottle start to move. The heavier objects, like the hammer, might not move much at all. This shows us how wind energy can move things, especially if they are light!
Now, let’s see how wind energy can do some work for us. Imagine we have a wind catcher that spins when the wind blows. We can attach a string to it and use it to lift an egg off the ground. As the wind catcher spins, it pulls the string and lifts the egg. Isn’t that cool?
Did you know that wind energy can help power our homes? Engineers and scientists build big machines called wind turbines. These turbines look like giant pinwheels. When the wind blows, it turns the blades of the turbine. Inside the turbine, there’s a generator that creates electricity. This electricity travels through wires to our homes, helping to light up our rooms and charge our devices!
Wind energy is just one of the many amazing types of energy that help us every day. Keep exploring and learning about the world around you. There’s so much science to discover! Thanks for joining us, and don’t forget to check out more fun videos and activities!
Make Your Own Pinwheel: Create a pinwheel using paper, a pencil, and a pin. Decorate your pinwheel with bright colors. Once it’s ready, take it outside on a windy day or use a fan to see how it spins. Think about how the wind makes it move. Can you feel the wind’s energy when the pinwheel spins fast?
Wind-Powered Boat Race: Use a small plastic container or a piece of lightweight material to create a simple boat. Place it in a shallow tub of water. Use a straw to blow air onto the boat and see how far it can travel. Try using a fan to see if it moves faster. Discuss with a friend or family member how the wind helps the boat move across the water.
Observation Walk: Go for a walk outside with a family member or friend. Look for things that are moving because of the wind, like leaves, flags, or swings. Make a list of everything you see that is using wind energy. Talk about how wind energy is helping these things move and why some objects move more than others.

Welcome to Kids Academy!
Hi everyone! It looks like our friend’s kite needs more wind energy to keep it flying. What is energy? Energy is the ability to do work or to make something happen. Let’s talk about some types of energy: light energy, heat energy, electrical energy, water energy, and wind energy. That’s a lot of different types of energy!
There’s one particular type of energy I want to talk about today, and that’s an invisible energy. It’s an energy you can’t see, but it’s all around us all the time. You might even feel it right now. It’s called wind energy. Wind energy can do all kinds of things, like blow this flag or help these kids keep their kite in the air. It can also help push this toy boat across the pond.
Something you might have used to harness wind energy is a pinwheel. If we want it to move, we have to use energy. I can use an invisible type of energy, and we all know what I’m going to do here—blow into it! That’s wind energy. Even though you can’t see it, it’s coming out of my mouth and hitting the blades of our pinwheel, making it spin.
Now, why don’t you give it a shot? Great job! That’s all energy, and this type is wind energy. Let’s do some experiments with wind energy.
Earlier, I explained how you can’t see wind energy; you can only see what it does. So, what we’ve set up here is a little experiment that you can try at home. It’s basically a wind tunnel. I have a simple house fan and a couple of different objects of different weights and densities: a hammer, a dollar bill, a regular pen, an empty water bottle, and an Easter egg.
I’m going to place all of these about the same distance from my wind machine. Now, I’m going to plug my wind machine into the wall. The wind machine will pull electrical energy from the wall down this cable into the machine and turn that electrical energy into wind energy. By definition, wind energy should be able to do work or move things. Let’s see if it works!
Now we’re stationed just behind the wind machine, and I’m going to fire it up to see if we can’t turn some of that electrical energy into wind energy and have it do some work for us. Which object do you think will move first: the egg, the empty water bottle, the pen, the dollar bill, or the hammer? Let’s fire it up!
There goes our dollar! Now our water bottle is definitely moving. We can see the energy being transferred into that bottle. The pen’s moving a little bit, and the egg seems to be wobbling. I’m going to turn up the energy a little bit to see if we can’t move some of this stuff. There goes the egg starting to move away! The bottle looks like it’s about to go now.
We got one more level; let’s see if we can really get it going. There goes the bottle! The dollar bill looks like it might be stuck under the hammer. Oh, there goes the dollar!
What we saw in this experiment was that the force from our fan, or the amount of energy, was able to move some of the lighter objects like the water bottle, the egg, and the dollar bill, while heavier objects like our hammer barely moved at all.
Now, let’s see if we can put some of that wind energy to work for us. What we’ve designed here is a wind catcher connected to our rod, which is loosely held on by some string. Down here, we’ve tied some string onto it, and I used two eggs to try and keep the string in place. You’ll see why I need those in a minute. Attached to that string is another egg.
Let’s see if we can take that wind energy and make it do some work for us and pick up that egg. Here we go! Look at our spoons rotating, spinning our shaft, and lifting the egg off the floor for us.
Now you might be wondering how wind energy like this can help around the house. Engineers work together with scientists to build large wind turbines. They look very similar to the pinwheel we used earlier today. Both catch that invisible energy called wind. As the wind blows, it creates force. That force, or wind energy, is able to turn the blades of our turbine. As the turbine spins, the generator inside creates electricity.
That electricity travels down wires across the power lines and into your home to light it up. When you go to charge something, you might actually be plugging into electricity generated by the wind.
Whoa, that’s a lot of science! Let’s go burn off some of our own energy. Subscribe to our channel to stay updated on new videos, and find links to our apps in the comments below!
