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.
For example, clay is matter relative to a brick because a brick is made of clay, whereas bricks are matter relative to a brick house. Change is analyzed as a material transformation: matter is what undergoes a change of form.For example, consider a lump of bronze that's shaped into a statue. Bronze is the matter, and this matter loses one form (that of a lump) and gains a new form (that of a statue).According to Aristotle's theory of perception, we perceive an object by receiving its form with our sense organs.or example, clay is matter relative to a brick because a brick is made of clay, whereas bricks are matter relative to a brick house. Change is analyzed as a material transformation: matter is what undergoes a change of form.
