The smallest part of an element which maintains
the properties of that element.
Changing one substance into another substance
resulting in a different arrangement of atoms and thus giving it new
characteristics or properties.
A shorthand way of writing down all the atoms and
molecules in a chemical reaction, showing both products and reactants.
The identifying characteristics of a substance; like color,
taste, heat content, effervescence, that makes substances behave or react
the way they do.
The process of oxidizing or burning a substance
that produces light and heat.
The ability to do work.
Kinetic, Potential, Chemical, Thermal, Nuclear,
Electrical, and Gravitational.
The process of going through the scientific method
to prove or disprove your hypothesis.
Anything that has mass and takes up space.
The smallest part that a chemical compound may
be divided into. In chemical form, these are expressed with the
chemical symbol and numbers representing the number of atoms of
that atom. An example is: H2O (water).
A chemical reaction that occurs in plants. Using light
energy, plants change Carbon Dioxide (CO2
) and Water (H2
to Sugar (C6
) and Oxygen (O2
The reaction is written as:
Changing characteristics of a substance such as; size,
shape, without affecting the chemical makeup of that substance.
Mainly the size and shape of a substance.
Any chemical substance formed as the result
of a chemical reaction.
The chemical substances that are used during a
The process of reviewing, analyzing, testing, experimenting,
and documenting discovery.
The process of using Oxygen(O2
) to break
) into Carbon
) and Water(H2
O). This reaction
is the opposite of photosynthesis. Instead of using energy, energy
is given off. The reaction is usually written as:
The process of oxidation; a chemical reaction that
combines O2 with iron to produce a reddish or brownish residue.
A measurement of the amount of heat energy contained
in an object. Scientists express temperature in degrees Celsius,
Fahrenheit, or Kelvin.
Things that can change in an experiment, equation,
or natural phenomenon that can effect the outcome.
