chemical: A compound shaped from two or extra atoms that unite (bond) in a mounted proportion and structure. For case in point, h2o is a chemical built when two hydrogen atoms bond to a person oxygen atom. Its chemical system is H2O. Chemical also can be an adjective to describe homes of products that are the outcome of many reactions concerning various compounds.

circuit: A network that transmits electrical alerts. In the entire body, nerve cells produce circuits that relay electrical alerts to the mind. In electronics, wires ordinarily route people alerts to activate some mechanical, computational or other function.

electrical engineer: An engineer who patterns, builds or analyzes electrical devices.

electrical energy: A movement of charge, usually from the motion of negatively billed particles, referred to as electrons.

electrode: A system that conducts electricity and is made use of to make contact with non-metal component of an electrical circuit, or that contacts one thing by way of which an electrical sign moves. (in electronics) Part of a semiconductor unit (such as a transistor) that both releases or collects electrons or holes, or that can control their motion.

electron: A negatively charged particle, typically discovered orbiting the outer regions of an atom also, the provider of electrical energy within solids.

electronics: Units that are powered by electric power but whose attributes are controlled by the semiconductors or other circuitry that channel or gate the motion of electrical expenses.

engineer: A man or woman who takes advantage of science to remedy problems. As a verb, to engineer indicates to structure a machine, content or procedure that will address some difficulty or unmet require. (v.) To complete these responsibilities, or the identify for a human being who performs such jobs.

natural environment: The sum of all of the items that exist all over some organism or the approach and the ailment individuals matters create. Natural environment may possibly refer to the temperature and ecosystem in which some animal life, or, maybe, the temperature and humidity (or even the placement of factors in the vicinity of an merchandise of interest).

gene: (adj. genetic) A phase of DNA that codes, or retains instructions, for a cell’s output of a protein. Offspring inherit genes from their mothers and fathers. Genes impact how an organism appears to be like and behaves.

gradient: From the term “grade,” it describes the incline, slope or diploma of maximize in some evaluate (these kinds of as temperature, stress or even color) that develops as one moves in time, posture or alongside some scale.

graduate student: An individual operating toward an highly developed degree by using courses and undertaking exploration. This do the job is done after the student has presently graduated from higher education (generally with a 4-calendar year degree).

eco-friendly: (in chemistry and environmental science) An adjective to explain products and processes that will pose little or no harm to dwelling issues or the surroundings.

humidity: A evaluate of the amount of money of water vapor in the ambiance. (Air with a great deal of h2o vapor in it is recognized as humid.)

iron: A metallic factor that is typical within just minerals in Earth’s crust and in its very hot main. This steel also is located in cosmic dust and in a lot of meteorites.

lightning: A flash of gentle activated by the discharge of electric power that happens involving clouds or among a cloud and a little something on Earth’s area. The electrical recent can trigger a flash heating of the air, which can make a sharp crack of thunder.

microbe: Short for microorganism. A dwelling issue that is way too modest to see with the unaided eye, which includes microbes, some fungi and quite a few other organisms this kind of as amoebas. Most consist of a solitary mobile.

microbiology: The review of microorganisms, principally micro organism, fungi and viruses. Researchers who review microbes and the bacterial infections they can lead to or strategies that they can interact with their surroundings are recognized as microbiologists.

molecule: An electrically neutral team of atoms that represents the smallest doable amount of a chemical compound. Molecules can be manufactured of solitary kinds of atoms or of distinct varieties. For instance, the oxygen in the air is manufactured of two oxygen atoms (O2), but water is made of two hydrogen atoms and a person oxygen atom (H2O).

nanotechnology: Science, technologies and engineering that deals with items and phenomena at the scale of a few billionths of a meter or considerably less.

nanowire: A wire or rod on the order of a billionth of a meter in cross-section or in circumference. It is usually made from some sort of semiconducting product. Nevertheless some micro organism make string-like anchoring buildings on the similar dimensions scale. Like the semiconductor wire, the bacterial types also can transport electrons.

novel: A thing that is clever or abnormal and new, as in in no way noticed ahead of.

oxide: A compound made by combining a single or much more features with oxygen. Rust is an oxide so is water.

pore: A tiny gap in a surface. On the skin, substances these kinds of as oil, water and sweat pass as a result of these openings.

protein: A compound made from 1 or additional extended chains of amino acids. Proteins are an critical aspect of all dwelling organisms. They kind the foundation of residing cells, muscle and tissues they also do the work inside of cells. Amongst the much better-recognised, stand-by itself proteins are the hemoglobin (in blood) and the antibodies (also in blood) that endeavor to struggle infections. Medicines frequently get the job done by latching onto proteins.

radioactive: An adjective that describes unstable features, such as particular forms (isotopes) of uranium and plutonium. Such components are stated to be unstable due to the fact their nucleus sheds power that is carried absent by photons and/or and normally a single or far more subatomic particles. This emission of strength is by a course of action identified as radioactive decay.

renewable electrical power: Energy from a source that is not depleted by use, this sort of as hydropower (water), wind electrical power or solar energy.

sea: An ocean (or location that is element of an ocean). Compared with lakes and streams, seawater — or ocean water — is salty.

technology: The software of scientific information for sensible functions, primarily in market — or the products, processes and programs that consequence from individuals endeavours.

threshold: A decrease limit or the most affordable degree at which a little something takes place.

voltage: A pressure associated with an electric recent that is calculated in models regarded as volts. Electric power firms use substantial-voltage to move electric electric power around prolonged distances.

squander: Any components that are left above from organic or other methods that have no worth, so they can be disposed of as trash or recycled for some new use.
