Once upon a time, there was a boiler named Boilie who lived in a steam engine factory. Boilie loved to invent new things and one day, he had an idea to expand his pressure capabilities by using diesel instead of coal. However, when he tried it out, something went wrong and BOOM! The steam engine exploded!
The other engines were shocked and worried, but Boilie had a plan. He fixed the engine, added more power, and created a new invention that made the locomotive run even faster! From that day on, Boilie was known as the greatest inventor in the steam engine world and all the engines admired his creativity and cleverness. The end.

Reflections

1. What was Boilie's invention?
2. Why did the steam engine explode at first?
3. How did Boilie fix the engine after the explosion?
4. What made Boilie the greatest inventor in the steam engine world?
5. Can you think of any other inventions that use steam or diesel as a power source?
