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.
The human body is made up of cells, and within every cell is a nucleus â everything else contained within the cell walls is the cytoplasm. This is one of many technical terms for the little building blocks of life within us all. Cytoplasm is material in a cell, such as mitochondria, that aren't the cell's nucleus and control the cell's metabolism. Cytoplasm is full of proteins, which are essential to your body. Cytoplasm is also called protoplasm.
