HEPA means high efficiency particulate air.ĭiatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake. Natural attenuation means the reduction in the con- centration and mass of a substance, and the products into which the substance breaks down, due to naturally occurring physical, chemical and biological processes. Natural uranium means uranium with the naturally occurring distribution of uranium isotopes, which is approximately 0.711 weight percent uranium-235, and the remainder by weight essentially uranium-238.

This video explains what they are and why they are important-all in just 60 seconds.Examples of Natural phenomena in a sentence Phenomena are important to science education because they give students tangible, interesting examples of science in the real world. They are also good opportunities for encouraging student inquiry: students can observe a phenomenon and subsequently ask questions and do research to find out more about how it works. But they are still observable events that can be explained with science and are therefore phenomena. Some phenomena occur very slowly and can be hard to notice, such as the passing of the seasons, the decomposition of organic matter, or the erosion of mountains. However, there are also a lot of phenomena that are less dramatic and less noticeable: simple things like light reflecting in a mirror, the way electricity passes through wires to allow you to switch on a lamp, or the simple fact that gravity allows us to walk on the surface of the Earth! Common examples of natural phenomena include lightning, earthquakes, tsunamis, volcanic eruptions, tornadoes, and similar.

Phenomena can be defined as “ observable events that occur in a natural or designed system.” They are everywhere around us, but some are easier to notice than others. Phenomena-based learning is at the core of the NGSS and many other science standards-but what are they, really? And why are they important? If you’re a science educator, you’ve probably come across the word “phenomena” countless times.
