Science Terms in Oakland County

Science Help: Glossary of Terms

Preparing your child for the STEM (Science, Technology, Engineering, & Mathematics) world that will face them as adults does not need to be a challenge. Here are a few terms your child should know. Test your children yourself and ask for examples where appropriate.
  • Absorbent- a substance that soaks up liquid, or energy, and retains it.
  • Acid- a chemical that neutralizes a base. By definition, acids contain a pH balance higher than 7. There are many kinds of acid- citric acid as found in lemons, acetic acid in vinegar, and hydrochloric acid.
  • Alloy- a metal formed by melting and mixing two or more metals together. For example, brass is a mixture of copper and zinc, and bronze is an alloy of copper and tin.
  • Amphibians- animals that live on both land and water. Their skins are smooth and moist and they lay eggs in water. Frogs and salamanders are well-known examples.
  • Bacteria- small, single-celled organisms with no nucleus. Some are harmful, like salmonella, while others are beneficial, like rhizobia, which convert nitrogen in soil.
  • Carnivores- animals that eat other animals. Lions and tigers and polar bears, oh my! Panda bears are herbivores, and all other bears are omnivores.
  • Catalyst- something that changes a chemical reaction without being permanently changed itself. A catalytic converter in a car's muffler contains platinum which changes carbon monoxide, a toxin, into carbon dioxide.
  • Circuit- one or more conducting paths between the two electrodes of a cell or a battery of cells.
  • Climate- the weather conditions of an area- an arid desert, or the frozen tundra.
  • Conclusion- the result of an experiment, including an explanation, judgment, or opinion based on interpretations.
  • Condensation- changing from a gas to a liquid or solid, like morning dew.
  • Data- a collection of observations, measurements, and facts.
  • Dilute- to make a liquid thinner, usually by adding water.
  • Dispersion- the splitting of white light into the seven colors of the visible spectrum, like a rainbow.
  • Ecosystem- the relationships between the environment, its animals, and its plants.
  • Electron- a small particle of matter with a negative charge that travels around the nucleus of an atom.
  • Enzyme- a biological catalyst, that is, a substance that speeds up a chemical reaction in the body.
  • Evaporation- the process of a liquid or solid changing into a vapor as a result of particles leaving the surface of the material.
  • Friction- the result of two surfaces rubbing against each other. Air resistance and water resistance are examples.

  • Gas- a state of matter in which the particles move really fast and are very spread out.
  • Habitat- the natural home of a plant or animal.
  • Herbivores- animals that eat only plants. Nature's vegetarians include panda bears, horses, and cows.
  • Insoluble- a solid that cannot transform into a liquid.
  • Insulator- something that stops electricity, heat, or sound from passing through.
  • Joule- a unit of measurement of energy or work.
  • Keratin- a fiber protein found in hair and nails.
  • Kinetic energy- the energy found in moving things.
  • Liquid- a state of matter in which particles are close together, but randomly arranged so that they can move over each other.
  • Melting point- the temperature at which a solid turns to a liquid.
  • Mixture- two or more substances that are mixed together, but not combined, so they can be separated later.
  • Molecule- a group of atoms joined together.
  • Neutralization- the reaction between an acid and a base. The result is salt and water.
  • Neutron- an uncharged particle found in the nucleus of an atom with similar mass of a proton.
  • Newton- the measuring unit of force.
  • Omnivores- animals that eat both plants and animals. Examples include humans, most bears, chickens, and cockroaches.
  • Opaque- does not allow light to pass through.
  • Permeable- a substance that allows liquids to flow through.
  • Photosynthesis- the process by which plants change sunlight into food.
  • Proton- an atomic particle found in the nucleus with a positive charge and the same mass as a neutron.
  • Refraction- the change in speed and/or direction when light or other waves travel from one material into another.
  • Residue- something that remains behind, left over.
  • Sedimentary- an element deposited by wind or water, or the matter that forms at the bottom of a liquid.
  • Solution (chemical)- a mixture of two or more substances. Solutions dissolve in a solvent.
  • Synthetic- substances that are not found in nature, but man-made by chemical reactions. Polyester and nylon are examples of synthetic fabrics, whereas cotton and wool are found naturally.
  • Texture- the appearance, feel, and structure of a substance.
  • Variables- factors that can change in an experiment.
  • Zero error- a systematic error usually resulting from a measuring instrument having an incorrect zero. One example is not realizing that the ruler edge is not zero.
