Section 45
Swimming etc.


The crawl, the backstroke, the breathstoke and the butterfly, what are these?
They are the different strokes we can use when swimming.
There are others, but these are the main ones.
These are strokes used for swimming on the water.
But what about under the water?
Snorkeling is a method of swimming on the surface while looking under the sea.
We use a tube which fix into our mouth for breathing, and a mask to help us see.
This way we can skim along the surface without bringing our head out of the water for air.
We use scuba 1 equipment if we want to go deeper and stay under the water for a longer time.
Scuba is an acronym 2 for Self Contained Underwater Breathing Apparatus 3.
Usually when scuba diving, we will wear a special waterproof 4 suit, a weighted belt, a mask, flippers and an oxygen tank.
In order to do this kind of diving, we should first be trained, as it can be dangerous.
Another form of diving is to plunge 5 into the water from above the surface.
This is also an event in the Olympic Games, which involves many different styles.
Synchronized 6 swimming is a form of dance performed in the water, and is also an Olympic event.
So we can use the water in many exciting and interesting ways.
