Conservation of mass – Conservation of mass refers to how the mass within a closed system remains the same regardless of the energy of transformations or processes acting within the system.
Conserved – Conserved means to remain the same in quantity or amount.
Convection – Convection is heat energy moving from one place to another due to the motion of the warm and cold masses of fluid.
Data – Data is observations and facts about concepts that can be used to calculate, reason, and draw conclusions.
Elastic potential energy – Elastic potential energy is the form of energy an object has when its shape is changed through stretching, compressing, twisting, and bending. Objects with elastic potential energy resist changes in shape and return to their original shape when released.
Energy – Energy is the ability to do work or cause change. Things change when there is an energy transfer.
Energy transfer – Energy transfer is the transfer of the energy of heat and or motion from one object or system to another.
Evidence – Evidence is what a person observes, reads or does, that strengthens a belief that something is true. It is important to know what the evidence is for a person to write statements or talk about a science investigation.
Food energy – Food energy is an example of chemical energy.
Force – A force is a push or a pull on something. A force is needed to change the motion of something.
Gases – Gases are atoms or molecules that are far apart and that move freely with random motion.
Gram – A gram is a metric unit of measurement used for determining the mass of an object or substance.
Gravitational potential energy – Gravitational potential energy is the potential energy an object or group of objects have in a system, due to the separation or height above the earth.
Heat energy – Heat energy is energy associated with the difference in the temperatures between objects. Heat energy can change things.
Heat transfer – Heat transfer relates to the transfer of heat from warmer objects to colder objects due to the motion of molecules.
Kinetic energy – Kinetic energy is the energy an object has due to motion.
Liquids – Liquids are atoms or molecules that are close together and that move in random motion.
Magnetic potential energy – Magnetic potential energy is the form of energy related to the distance between the magnetic materials.
Mass – Mass is the measure of the amount of matter in an object. The mass of an object remains the same no matter what the gravitational pull.
Molecules – Molecules are two or more atoms that bond together as the basic unit of elements or compounds.
Motion – Motion is the changing of position. Motion can be described in changes of distance, time, and or direction.
Motion of molecules – The motion of molecules is the particular way that molecules move.
Newton – A newton is a metric unit used for measuring force. Weight is the measure of the force of gravity and can be measured in newtons.
Potential Energy – Potential energy is often described as “stored energy”. Potential energy is energy an object has due to its shape or position.

Solids – Solids are atoms or molecules that are very close together and that move within fixed positions in a rigid structure.
Spring Scale – A spring scale is a tool used to measure the force on an object.
State of matter – State of matter describes whether a substance is a solid, liquid, or gas.
Thermal contraction – Thermal contraction is a physical change in which matter becomes more dense due to temperature changes.
Thermal expansion – Thermal expansion is a physical change in which matter increases in size due to temperature changes.
Transformation – Transformation of energy refers to the changing or conversion of one form of energy to another.
Variables – Variables are the properties of things that can change, be changed, or vary in an investigation. Variables can affect the results of an experiment. Some examples of variables are time, distance, and temperature.
