LESSON 2: SNORKELING PEH 104 PREPARED BY: GDC LEARNING OBJECTIVES AT THE END OF THIS SESSION THE STUDENTS SHOULD BE ABLE TO: UNDERSTAND THE MEANING SNORKELING ENUMERATE THE DIFFERENT PARTS OF SNORKEL AND MASK AQUATIC ACTIVITIES CAN BE DONE IN WATER SUCH AS SWIMMING AND SNORKELING, ON WATER (SURFACE WATER) SUCH AS SURFING AND WHITEWATER RAFTING AND UNDER WATER SUCH AS SCUBA DIVING SNORKELING  SNORKELING It allows one not only to grasp the amazing beauty of marine life, but swim with them as well. Snorkeling is peeking through life underneath water by swimming with the aid of a snorkel and mask. HOW DID SNORKELING BEGIN? 01 0 02 0 03 0 ANIMAL SKIN HOLLOW REED1 2 DIVING BELL 3 WERE FILLED 3000 B.C WITH AIR 900 B.C 300 B.C. 04 0 05 0 06 0 Eye goggle 4 WOODEN 5 Modern fins 6 from shells of PADDLES 1717 1912 tortoise 1300s  Skin divers of the island create in the HOLLOW Mediterranean used REED hollow reeds to breath 3000 B.C. while submerged in water as they collected sponges  Animal skins were filled with air 900 B.C An ancient bas-relief dating 900 B.C. depicted divers in Assyria using animal skin with air to lengthen their stay underwater.  DIVING BELL 300 B.C. Alexander the great encouraged the development of the first diving bell, which was a cauldron designed to trap a pocket of air when it was lowered into the water. This instrument allowed divers to take breaths without needing to go all the way up to the surface to gulp air, but it also limited their mobility..  Eye goggle from shells of tortoise 1300s The shell of the tortoise was used to develop a gadget to protect the eyes as well as to see more clearly in water. It was then used by the Persian divers.  WOODEN PADDLES 1717 Benjamin Franklin came up with an idea of using wooden paddles attached to the hands and feet to help swimmers swim faster.  Modern fins 1912 Modern fins were invented by Frenchman louis de corlieu. Patent for this was obtained in 1933. The basic gears needed in snorkeling are: SNORKEL GOGGLES/MASK FINS FLOATING VEST RASH GUARD. MASK – the mask serves as the viewing device in appreciating the world beneath the water. There are two most important things to remember on choosing a mask. These are fit and comfort. Parts of the Mask: 1. Strap – Holds the mask to the face underwater. 2. Mask Skirt – Is the soft flexible material that seals the mask around the face. 3. Nose pocket –Protects the nose. Some masks have the purge valve, a little flap valve located at the bottom of nose pockets that helps in removing the water that has entered. SNORKEL – The snorkel is a piece of equipment that makes it possible to breathe at the surface while the face is submerged in water. The snorkel is basically composed of a tube, also called the barrel, and a mouthpiece. 2 types of snorkel  CLASSIC SNORKEL has the most basic part, the solid tube and the mouthpiece. Sometimes, this can be bent to a specific shape.  Snorkel with a flexible tube below the strap attachment point is more comfortable than the classic snorkel. The flexible tube allows the top and mouthpiece to rotate to different angles to better fit the face. It can also drop away from the face when not in use. PARTS OF SNORKEL 1. Purge Valve This is a small valve just lower than the mouth that empties the collected water that comes down the tube when one blows it out 2. Splash Guard Prevents splashed water and spray for easily entering the tube. However, this will not stop water from entering the tube when a big wave covers the snorkel or when one goes underwater.  3. Dry Valve Is a special valve on top of the tube that completely stops water (and air) from entering the tube when a wave comes or when diving underwater. This way, one does not need to clear the water out when coming back to the surface.
