In the chapter ‘The Wright Brothers’, you read about the titular
brothers’ quest to invent a flying machine. Their contribution led to
the development of the modern airplane and air travel.

Now, in groups of five, think of one invention that changed the
course of humankind forever, and which continues to help us in our
day-to-day lives. Make a PowerPoint presentation as a group and
choose a representative to present it before the class. Remember to
cover the following points:
• What was the invention?

• Who invented it and when?

• What led to the invention? (historical contribution of other people
towards the invention)
• How did it impact the lives of the people living at that time?

• How is the invention used in modern times?
• What are the other scientific discoveries that were possible due

to this invention?
