Lesson Introduction

Think About It

Today, we are going to learn about an amazing inventor named Thomas Edison. Thomas Edison did something incredible that changed the way we use light in our homes.

You know those bright light bulbs you have at home? Well, a long time ago, they weren’t as good as the ones we have today. They didn’t shine for very long, and they were quite expensive. That’s where Thomas Edison comes in.


Thomas Edison wanted to make a better light bulb, one that could shine for a long time and that was affordable for everyone. So, he worked really hard with his innovative team. He experimented with a lot of different materials to improve the light bulb.

After trying many things, he finally found the right material that made the light bulb last a long time. It was called a ‘carbonized bamboo filament,’ which is a fancy way of saying a special kind of string that glows when electricity passes through it.


When Edison and his team used this new filament in their light bulbs, it was a huge success! The light bulbs stayed lit for a long time, and people had brighter and safer light in their homes without using smelly gas lamps or candles.

Because of Thomas Edison’s hard work and clever thinking, we have the light bulbs we use today, and we can read, play, and do our homework comfortably in well-lit rooms. Edison changed the world and made our lives much better!
