• Outdoor recreation is organized activities done during one’s free time for his/her own personal reasons, where an interaction between man and an element of nature is present.
• Recreation is derived from Latin word RECREARE which means “to be refreshed”.
• There are three types of days: Existence, Subsistence, Free time.
• Existence Time is the time spent for biological needs like having meal, sleeping and other personal care.
• Subsistence Time refers to the hours spent for economic purposes such as going to work, chores, and for students going to school.
• Free time is all the remaining time.
• Snorkeling is peeking through life underneath water by swimming with the aid of a snorkel and mask.
• Bouyancy is the upward force of water on an object.
• Enhanced Cooling is the process of transferring the heat away from the body much quicker than air given in the same temperature.
• Hydrostatic pressure is the pressure exerted by the water at equilibrium due to the force of the gravity.
• Alexander the Great encouraged the development of the first diving bell.
• Leonardo De Vinci proposed and created the first contemporary snorkel.
• Benjamin Franklin came up with the idea of using wooden paddles attached to the hands and feet to help swimmers swim faster.
• Frenchman Louis de Corlieu invented the modern fins.
• A mask serves as the viewing device in appreciating the world beneath the water.
• A strap holds the mask to the face underwater.
• A mask skirt is the soft flexible materials that seals the mask around the face.
• A snorkel is a piece of equipment that makes it possible to breathe at the surface while the face is submerged in the water.
• A classic snorkel has the most basic part, the solid tube and the mouthpiece.
• A purge valve is a common feature of many snorkels.
• A dry valve is a very special valve on top of the tube that completely stops the water from entering the tube when a wave comes or when diving under water.
• A snorkel vest is small and inflatable, which provides buoyancy with floating on water.
• A swimming cap helps in keeping hair out of the snorkel and the face as well.
• A mask defogger helps prevent the mask from fogging up.
• Fogging is when the lens of mask becomes hazy or obscured with tiny droplets of moisture that are formed on the lens inside the mask.
• When camping, keep the campsite small and discreet.
• Avoid places where impacts are just beginning to show.
• Respect people who live and work in the countryside.
• Avoid introducing non-native plants and animals.
• Examine archeological structures, old walls, and other heritage artifacts but do not touch nor leave marks on them.
• Burn all wood to ash and make sure fires are completely out.
• Use lightweight stove for cooking; campfires can cause lasting impacts.
• Observe wild animals from a distance and they should be avoided during sensitive times such as mating, nesting, or raising the young.
• When camping, cat holes are dug (6 – 8 inches deep) for human waste and covered just the same with soil and weeds or leaves on top.
• “Pack it in, pack it out” means everything you brought should be brought back with you including left-over food or fruit peel.
• Never burn plastics or other substances that emit toxic fumes.
• Vegetation damage can occur when trampling on a young tree or pasture.
• Do not feed wild animals or birds as it is not their natural food; the food might damage their health or alter their natural behaviors and even expose them to predators.
• Allow the sound of nature to prevail, not your noise or your radio.
• Be courteous; yield to others on a trail.
