2D: Refers to two-dimensional objects that exist in a flat world, with characteristics defined by width and length.
3D: Refers to three-dimensional objects that have characteristics defined by height, width, and length.
atom: The basic unit of a chemical element, consisting of a nucleus with protons and neutrons surrounded by electrons.
carbon: A fundamental element essential for life on Earth, existing as graphite, diamond, and in various compounds with great importance.
catalyst: A substance that speeds up chemical reactions, such as enzymes or elements like platinum and iridium.
chemicals: Substances formed by atoms combining in specific ratios and structures, with properties determined by their molecular composition.
Chemical reaction: A process involving rearrangement of molecules rather than a change in physical form.
electronics: Devices powered by electricity and controlled by semiconductors or circuits.
element: A fundamental substance with the smallest unit being a single atom, including hydrogen, oxygen, carbon, and more.
fuel: Substances releasing energy in controlled reactions, such as fossil fuels like coal, natural gas, and oil.
Graphene: Ultra-thin, ultra-strong material made of single atomic layers of carbon atoms.
hydrogen: The lightest element, essential in fuels, fats, and living tissues, consisting of one proton and one electron.
metal: Material that conducts electricity well, is shiny, and malleable.
molecule: Group of atoms representing the smallest amount of a chemical compound, like oxygen (O2) or water (H2O).
particle: A trace amount of something.
phosphorus: A reactive nonmetallic element found naturally in phosphates, crucial in cellular chemicals and structures.
sensor: Device measuring physical or chemical conditions and transmitting that information for analysis.
solution: A liquid where one chemical is dissolved in another.
