ACTIVITIES
Lesson 5: B3 - 5
Most of the world’s surface is water. We may know the land very well, but we know very little about the oceans.
Until recently, man could not stay underwater for long. A pearl diver, for example, couldn’t stay underwater for longer than two minutes. But now, with special breathing equipment, a diver can stay underwater for a long time. After the invention of this equipment, man could swim freely underwater and scuba-diving became a popular sport.
A Frenchman, Jacques Cousteau ( 1910-1997), invented a deep-sea diving vessel in the early 1940s. In the vessel, he could explore the oceans of the world and study the underwater life.
Now, we can explore the oceans, using the special TV camera as well. We can learn more about the undersea world thanks to this invention.
