Walk as fast as you can in a circle around a section of the pool that's about 3 feet deep (the more people, the better the effect). Do about 20 laps, then change direction for 10 laps. The resulting rush of water against your body will feel much like the jets in a whirlpool.
Elements and Compounds. All matter in the natural world is composed of one or more of the 92 fundamental substances called elements. An element is a pure substance that is distinguished from all other matter by the fact that it cannot be created or broken down by ordinary chemical means.
Atoms of the four elements Carbon, Hydrogen, Oxygen and Nitrogen combine with traces of other elements to produce the molecules that make up the building blocks of our cells, amino acids. DNA (deoxyribonucleic acid) in the nucleus of cells acts as both the hardware and software of a system that uses amino acids to create proteins.
