Swimming under the sea, looking at ocean life, is a very popular pastime, but there was a time when SCUBA diving did not exist. People had to wear very heavy diving suits, boots, and helmets. They could not swim freely and easily. Jacques Cousteau changed all that. Students read about his invention of the Aqua-Lung and how his love of swimming as a boy led to a lifetime of adventure, movie-making, and discovery.
