Welcome to Science Madness, where we explore and learn about exciting things! Today, we’re going to talk about different types of electricity and how circuits work. Are you ready? Let’s dive in with some fun questions!
Have you ever walked on a carpet and felt a tiny shock when you touched something? Or noticed your hair sticking to a brush after combing it? This happens because of static electricity! Static electricity is created when objects rub against each other.
Everything around us is made of tiny particles called atoms, which have electric charges. These charges can be positive or negative. When two objects rub together, they can transfer these charges, creating an imbalance. This imbalance is what we call static electricity.
Sometimes, static electricity makes things stick together, like your hair and a brush. This happens because the brush gets more positive charges, and your hair gets more negative charges. Opposite charges attract each other, which is why your hair sticks to the brush. But, hairs with the same charge push away from each other, making them stand up!
Static electricity is fun, but it doesn’t last long. We can’t use it to power our phones or lamps. For that, we need dynamic electricity. Dynamic electricity is like a river of electric charges flowing continuously.
To make this flow happen, we need a circuit. A circuit is a closed path that allows electric charges to travel. It has two main parts: a source of electricity and materials that let the charges flow.
Let’s look at a flashlight to understand circuits better. Inside the flashlight, there are batteries that provide electricity. There are also wires that carry the electric charge to the bulb. When you turn on the switch, the electric charges flow through the wires, and the bulb lights up. When you turn off the switch, the charges stop, and the light goes out.
Think of a circuit like a drawbridge. When the bridge is down, cars can drive across. Similarly, when the circuit is complete, electric charges can flow and power things like lights and gadgets.
Now that we’ve learned about electricity, let’s see what you remember! Static electricity is when there’s an imbalance of charges between two objects. Dynamic electricity is the flow of electric charges, like water in a river. Great job learning about electricity and circuits!
Thanks for joining us on this adventure! There’s so much more to discover, so keep exploring and having fun with science!
Static Electricity Experiment: Try this fun experiment at home! Rub a balloon on your hair for about 10 seconds. Then, slowly bring the balloon close to small pieces of paper or your hair again. What happens? Write down your observations. Can you explain why the paper or your hair reacts to the balloon? Discuss with your family or friends how static electricity is at work here.
Build a Simple Circuit: With the help of an adult, gather a small battery, a light bulb, and some wires. Try to connect them to make the light bulb glow. Can you make the bulb light up? If not, what might be missing in your circuit? Draw a picture of your circuit and label the parts. Think about how electricity flows through your circuit like a river.
Electricity in Everyday Life: Look around your home and make a list of things that use electricity. Are they using static or dynamic electricity? How do you know? Share your list with a classmate and see if they found anything different. Discuss why dynamic electricity is more useful for powering devices in your home.

Welcome back to Science Madness, a program where we discover, learn, and experiment with new things! In our last video, we learned what electricity is and where it comes from. Today, we’re going to learn about types of electricity and circuits. Are you ready? Let’s start with a couple of questions!
Have you ever walked across a carpet and later felt a small shock when you touched an object? Yes? And have you ever brushed your hair for a while and noticed how it got stuck to your brush? Good! Well, this happens because of static electricity, which means that an electric charge is created when objects rub against each other.
Let me explain: all objects are made up of atoms that are too small to see. These atoms have different electric charges: positive or negative. When two objects rub against each other, they become charged with energy, and the negative charges move, creating an imbalance. We call this imbalance static electricity.
Sometimes, static electricity causes two objects to stick together or attract each other, such as hair and a brush. When we comb our hair, the brush has more positive charges, and the hair has more negative charges. Positive and negative charges attract each other, while atoms with the same charge repel each other. This is why you will notice that hairs want to separate from each other; each strand of hair is negatively charged.
Now we know why sometimes some objects give us a shock—it’s because we transfer the excess electrical charge from one object to another.
Now that we know what static electricity is, let’s look at dynamic electricity. Static electricity only lasts a short time; we can’t use it to charge our cell phones or turn on a lamp. We need a different type of electricity using the natural resources around us. As I explained in our last video, the electricity we receive at home to run our electronic devices is called dynamic electricity. Dynamic electricity is the flow of electric charges, just as water flows in a river.
In order for electrical charges to flow continuously, we need a circuit. A circuit is a closed path in which electrical charges travel. Circuits have two parts: the first is the source of electricity, which we discussed in the previous video, and the second corresponds to the materials that allow the flow of electric charges.
Here, we see an electric circuit inside this flashlight. There are two batteries, which are the source of electricity, and the wires that carry the electric charge to the bulb. If I turn on the switch, the electric charges begin to flow through the wires, and the bulb emits light. If I turn off the switch, the electrical charges stop flowing, and the bulb stops emitting light.
This works the same as a drawbridge: when its parts are lowered, cars can go back on the road. The same is true for the electrical charges in a circuit.
Alright, now that we’ve learned all about the types of electricity and circuits, let’s see what you remember! An imbalance of positive and negative charges between two objects is called static electricity. That’s it! And the flowing of electric charge is called dynamic electricity. Very good! Great job!
See you at the next show—don’t miss it!
