1-5
Well tested and widely accepted description of observations that have been repeated many times in a variety of conditions.
Scientific Theory
Type of matter with a unique set of properties that cannot be broken down into simpler substances by chemical means
Element
Atom or group of atoms with one or more positive or negative electrical charges
Ion
energy is neither created nor destroyed
Law of conservation of energy
Forms of kinetic energy traveling as electromagnetic waves.
Electromagnetic radiation
Factual information collected by scientists
Data
Capacity to do work
Energy
One or two more forms of a chemical elements that have the same atomic number but different mass numbers because they have different numbers of neutrons in their nuclei
Isotope
Change in the chemical composition of a substance,
Chemical CHange
Energy stored and potentially available for use.
Potential Energy
a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Hypothesis
Anything that has mass and take up space. It commonly exists as solid, liquid, or gas
Matter
Combination of two or more atoms of the same or different elements held together by chemical bonds.
Molecule
Process that alters one or more physical properties of matter without changing its chemical composition.
Physical change
Energy associated with motion, such as energy in flowing water, a speeding car, or electricity.
Kinetic energy
Practice used by scientist to ask questions, gather data, and formulate and test hypotheses
Scientific Method
the evaluation of work by one or more people with similar competencies as the producers of the work (peers).
Peer Review
The basic building block of matter.
Atom
Compound that contains at least two carbon atoms combined with atoms of one or more other elements
Organic compond
the energy contained within a system that is responsible for its temperature
Thermal Energy
Broad field of study focused on discovering how nature works and using that knowledge to describe what is likely to happen in nature.
Science
Description of what scientist find happening in nature repeatedly in the same way, without known exception.
Scientific Law
Combination of two or more different elements held together in fixed proportions.
Compound
Numeric Value that indicates the relative acidity or alkalinity of a substance on a scale of 0 to 14, with the natural point at 7
pH
in a chemical reaction mass is neither created nor destroyed.
Law of conservation of mass
