The worksheet asks why Thomas Edison’s invention of the electric light bulb helped the world.
Let’s think step by step:
1. Before electric light bulbs, people used candles, oil lamps, or gas lights to see at night.
2. These older ways were dangerous (could cause fires), dim, and needed constant refilling or trimming.
3. Edison’s electric light bulb was safer — no open flame.
4. It was brighter and lasted longer.
5. You could turn it on and off with a switch — very convenient!
6. Electric lighting let people work, study, and do activities after dark — which changed daily life forever.
7. Factories could run at night. Streets became safer with streetlights. Homes became more comfortable.
So, the big reason his invention helped the world is:
→ It gave people safe, reliable, bright light anytime — day or night — which improved safety, productivity, and quality of life.
Final Answer:
It provided safe, bright, and convenient light that allowed people to be active after dark, improving daily life, work, and safety around the world.
