VOCABULARY
REVIEW
Abiotic
All the non-living
matter in an
environment.
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
Proteins are sometimes
described as long necklaces
with different colored beads.
Each bead is a small
amino acid. The amino
acids join to make
different proteins.
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.

Albert Einstein
(March 14, 1879 - 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.
