Matter
Characteristics that describe how one kind of matter is different from another.
Properties
One of the most important sources of energy for earth that comes from the sun
Electromagnetic Radiation
A simple machine that consists of two incline planes that work when they move.
Wedge
Energy can be neither created nor destroyed, only changed in form.
Conservation of Energy
A mental model—a conceptual representation of how part of the world works.
Scientific theory
The smallest chemical unit of an element.
Atom
Energy that is stored somehow, but which can be released from storage and put to use
Potential Energy
A simple machine that consists of an incline planes wrapped around a cylinder or cone.
Screw
What objects/substances have reached when they are all at the same temperature, and no heat is flowing between them.
Thermal equilibrium
An informed prediction, based on a theory
Hypothesis
The three 3 subatomic particles within an atom
Electron, neutron, proton
Heat energy that comes from the earth
Geothermal energy
A simple machine consisting of a bar that rotates around a fixed point called a fulcrum.
Lever
Thermal energy
Reconsidering experimental methods, appropriateness of hypothesis, adequacy of theory
Review
A substance characterized by being composed of atoms all possessing the same number of protons in the nucleus.
Element
Energy stored in the chemical bonds holding together the molecules.
Chemical potential energy
A simple machine that consists of 2 connected rings or cylinders, one inside the other. Both wheels turn in the same direction around a single point. The smaller, inner cylinder is called the axle while the bigger, outer ring is called the wheel.
Wheel and axle
This is the transfer of heat through a material without the material itself moving. Occurs in solids, the solid most readily heated is metal
Conduction
Determining if the results are consistent with the theory we started with, and if the hypothesis is supported
Analysis
What is formed any time atoms of two or more different elements are chemically bonded together.
Compound
The nuclear process where atoms are split apart, creating energy
The force a person exerts on a machine.
Input force
The type of energy that is transformed from the chemical energy of gas in a car.
Kinetic
Replicate
