atom: Refers to atoms, which are the smallest units that compose chemical elements.
chemicals: Substances formed when two or more atoms combine in a specific proportion and structure. For example, water is a chemical produced when two hydrogen atoms combine with one oxygen atom, with the chemical formula H2O. Chemistry can also describe the properties of materials resulting from reactions between different compounds.
data: Facts and/or statistics collected for analysis. They may not be organized in a way that gives them meaning. For digital information stored by computers, data are typically numbers stored in binary code and represented as strings of 0’s and 1’s.
melt: Changing a solid into a liquid and dispersing it. For example, solid sugar or salt crystals dissolve in water, resulting in a liquid mixture.
force: External influences that can alter the motion of objects, bring objects closer together, or cause stress in stationary objects.
hydrogen: The lightest element in the universe. It is colorless, odorless, and highly flammable. Hydrogen is essential in fuels, fats, and chemicals found in living tissues, consisting of a single proton as the atomic nucleus orbited by a single electron.
information: Facts or trends learned about something or someone, often resulting from the study of data.
insoluble: Unable to dissolve in liquids or gases. For example, salt and sugar dissolve in water, but substances like proteins do not.
ion: An atom or molecule that becomes electrically charged by losing or gaining one or more electrons. An ionized gas or plasma is a state where electrons are separated from their atoms.
Manufacturer: Refers to people who create their own products rather than buying commercial versions. Many manufacturers now use 3D printers to produce items when needed.
molecule: An electrically neutral group of atoms representing the smallest amount of a compound. Molecules can consist of one type of atom or different types. For example, oxygen in air has two oxygen atoms (O2), while water has two hydrogen atoms and one oxygen atom (H2O).
monitor: To test, sample, or observe something regularly or continuously.
oxygen: A gas comprising about 21% of the Earth’s atmosphere. Oxygen is essential for the growth and metabolism of animals and many microorganisms.
physics: The scientific study of matter and energy. Classical physics explains matter and energy based on descriptions like Newton’s laws of motion, while quantum physics provides a more precise description of matter’s motion and behavior.
polarization: In physics, the state in which light rays show different properties when viewed from different angles.
salt: A compound formed by combining an acid and a base, with water produced as well. The sea contains various salts collectively called “sea salt,” while common table salt is made of sodium and chlorine.
solid: A stable, solid shape that is neither a liquid nor a gas.
soluble: A chemical substance that can dissolve in liquids, forming a solution.
solution: A liquid where one chemical is dissolved in another.
solvent: A substance, usually liquid, used to dissolve other substances in a solution.
weather: The atmospheric conditions at a specific location and time, described by characteristics like barometric pressure, humidity, precipitation, temperature, and wind speed. Weather is a real-time occurrence, unlike climate which refers to general conditions over a particular period in a broad area.
