Okay kiddo, let me explain the timeline of steam power to you in a simple way.
Steam power is a way of using steam to produce energy for machines. It all started with a man called Hero of Alexandria, who lived a very long time ago, like more than 2,000 years ago! He invented something called an aeolipile, which was like a spinning ball that used steam to spin it around.
But it wasn't until the 1700s that people started to really use steam power, and it was thanks to a man called James Watt. He improved upon an earlier design of a steam engine and made it more efficient. This meant that factories could use steam engines to power their machines, which made it easier and faster to make things like textiles and pottery.
Then, in the 1800s, there were many advancements in steam power. Steam engines were used to power trains, ships, and even some cars. This made transportation much faster and more efficient.
But as time went on, people started to look for more environmentally-friendly ways to power machines, and steam power became less popular. Nowadays, we use electricity to power most of our machines.
So, that's the timeline of steam power. It started a really long time ago with Hero of Alexandria, then James Watt made steam engines more efficient in the 1700s, and in the 1800s steam power was used for trains, ships, and cars. But now we mostly use electricity instead.
