ClassX Video Lessons Youtube Channel Learning Junction Invention of Electricity? – Discovery of Electricity
Hello friends! Today, we’re going to learn about the discovery of electricity. Have you ever imagined what life would be like without electricity? Without it, we wouldn’t have our favorite video games, glowing lights at night, or mobile phones for online classes. But don’t worry—electricity is here, and it makes life a lot more fun and convenient!
Electricity is a form of energy that has always been around in the universe. It wasn’t invented by anyone; instead, it was discovered. Many people think of Benjamin Franklin when they think about the discovery of electricity. He was an American who loved to learn about many things, including electricity, back in the 1700s.
Before Franklin’s time, scientists mostly knew about static electricity, which is the kind of electricity you might feel when you rub a balloon on your hair. Franklin had some new ideas about electricity. He thought it had positive and negative parts and that it could flow between these parts. He also believed that lightning was a form of this flowing electricity.
On June 10th, 1752, Franklin did something very brave and interesting. He flew a kite during a thunderstorm! He tied a metal key to the kite string to see if lightning was really electricity. When the thunderclouds passed over the kite, the loose threads on the kite string stood up. When Franklin touched the key, he felt a shock, proving that the kite was conducting electricity. This experiment showed that lightning is indeed a form of electricity.
After Franklin’s exciting experiment, other scientists became interested in studying electricity too. They learned more and more about how it works. In 1879, a man named Thomas Edison made a big breakthrough by inventing the electric light bulb, which changed the world forever!
Did you know that electricity travels at the speed of light? That’s about 186,000 miles per second! It’s super fast, which is why when you flip a light switch, the light comes on almost instantly.
So, thanks to Benjamin Franklin and many other scientists, we now have electricity to power all the cool things we use every day. Isn’t that amazing?
Electricity Scavenger Hunt: Take a walk around your home or classroom and make a list of all the things that use electricity. Look for items like lights, computers, and kitchen appliances. Discuss with your friends or family how life would be different without these items. Can you think of any ways to do these tasks without electricity?
Static Electricity Experiment: Try creating static electricity at home! Rub a balloon on your hair and then slowly bring it close to small pieces of paper. Watch as the paper jumps up to the balloon! Discuss why you think this happens and how it relates to what you learned about static electricity.
Lightning in a Jar: With the help of an adult, create a simple “lightning” experiment. You’ll need a clear plastic jar, a small piece of aluminum foil, and a wool cloth. Place the foil inside the jar and rub the wool cloth on the outside of the jar. Turn off the lights and watch closely. Can you see tiny sparks? Talk about how this is similar to Franklin’s kite experiment and what it tells us about electricity.
Sure! Here’s a sanitized version of the transcript:

Hello friends! Today, we’ll learn about the discovery of electricity. Have you ever thought about what life would be like without electricity to power your favorite video games, the glowing lights at night, mobile phones for online classes, or other things? But don’t worry—electricity does exist, and it allows you to enjoy life in many ways.
Electricity was never invented; it’s a form of energy that has always existed throughout the universe, so it was discovered. Most people give credit to Benjamin Franklin, an American polymath, for discovering electricity in the mid-1700s. He became interested in the study of electricity, and until that time, scientists had mainly known about static electricity, which is typically produced by friction. Franklin advanced the understanding of electricity by proposing that it has positive and negative elements and that electricity flows between these elements. He also believed that lightning was a form of this flowing electricity.
On June 10th, 1752, Franklin conducted an experiment known as the kite experiment to demonstrate that lightning was electricity. He flew a kite during a thunderstorm and tied a metal key to the kite string to conduct electricity. This experiment showed the connection between lightning and electricity. When thunderclouds passed over the kite, Franklin noticed that the loose threads on the kite string began to stand on end. He then touched his knuckle to the key and received an electric shock, proving that the kite was conducting electricity.
Building upon Franklin’s work, other scientists also began to study electricity. In 1879, Thomas Edison
