SCIENCE VOCABULARY REVIEW

All the non-living matter in an environment. Abiotic

Biotic All the living matter in an environment.

Amino acid sequence The order of amino acids in a protein or peptide chain. The primary structure determines the protein type

Protein An organic compound that is made of one or more chains of amino acids. Is a principal component of all cells

Protein Each bead is a small amino acid. The amino acids join to make different proteins. Proteins are sometimes described as long necklaces with different colored beads.

Antoine Lavoisier French chemist know as the father of modern chemistry

Accelerator A substance that speeds up a chemical reaction

Accelerator When you push on the car accelerator the car goes faster.

Accelerator

Albert Einstein (March 14, April 18, 1955) A theoretical physicist, born in Germany, who is widely regarded as the greatest scientist of the 20th century. He proposed the theory of relativity and also made major contributions to the development of quantum mechanics, statistical mechanics, and cosmology.

Albert Einstein His famous equation that the energy of a body at rest (E) equals its mass (m) times the speed of light (c) squared:

Atomic bomb Its violent explosive power is due to the sudden release of energy. The energy is a result from splitting the nuclei of elements by neutrons in a very rapid chain reaction

Atomic bomb

John Dalton English chemist and physicist who formulated atomic theory and the law of partial pressures

Atomic theory A theory that states that all matter is composed of tiny particles called atoms

Atomic configuration The arrangement of atoms or groups in a molecule

Atomic mass The average mass of all the known isotopes of an element

Atomic number The number of protons that an atom contains

Electron A subatomic particle in an atom that is negatively charged and occupies an energy level outside the nucleus

Proton Positively charged particle in the nucleus of an atom. Has a positive charge.

Neutron A subatomic particle found in the nucleus of an atom. It has no charge = Neutral.

Periodic Table of the Elements

Alfred Wegener German meteorologist and geophysicist who formulated the first complete statement of the continental drift hypothesis

Plate tectonics Theory that Earth’s crust and upper mantle are broken into plates that float and move around on a plastic like layer of the mantle

Daniel Gabriel Fahrenheit German physicist who invented the mercury thermometer and developed the scale of temperature that bears his name

Fahrenheit A scale used to measure temperature Water freezes at 32 degrees Fahrenheit

Big Bang theory The theory that the universe originated from the cataclysmic explosion of a small volume of matter at extremely high density and temperature.
