My opinion on why I think the light bulb is the technological outcome that changed mankind.The Light BulbBy Grant
Reason 1: • Without the light bulb we would need to use fire to see. This would be dangerous. So the light bulb is helping to make us safer.
Reason 2: • If the light bulb wasn't invented we would have to use kerosene oil which is a fossil fuel and would be less environmentally safe.
Reason 3: • Its used in lighthouses to stop ships from crashing into rocks and shore.
Reason 4: • It lights our way so at night in the dark we will know where we are going.
Reason 5: • Headlights on cars light the road so they wont crash into other cars.
Reason 6: • Light bulbs in torches allow us to see in caves, forests and used in emergencies.
Reason 7: • Light bulbs attached to microscopes allow us to see very small objects and insects
Reason 8: • Light bulbs in operating theatres allow surgeons to perform the most complicated operations.
Thanks For listening to my illuminating presentation • That's why I think the light bulb is the technological outcome that changed mankind.
