You should talk about:

How it affected the human community
It is really difficult to choose a specific scientific invention that has had a positive impact on mankind. I would like to single out the “light bulb” as one such invention that has had a very positive impact on the human race.
This unique invention of science has promoted the human race towards prosperity and the modern world. Think of a world without any lights in the dark and we would be no different than living in a cave. The great scientist “Thomas Edison” is known as the inventor of the light bulb, and many improvements have been made since then.
The light bulb is the main source of light at night. We are so used to electricity and light bulbs that we may wonder if this is a life-changing invention or not.
But think about living without a light bulb for a few days and then you will realize the real importance of this invention.
Scientific inventions are interrelated, and one invention or theory inspires and catalyzes the invention of other important inventions.
The lamp is one of these inventions that inspired the invention and research of other inventions. It is the only invention that has freed us from working only during the day when the sun is there.
