mixture		The capacity of a substance to combine chemically with another substance
criticalthinking		A factor that changes in an experiment in order to test a hypothesis.
molecule		The temperature and pressure at which a solid becomes a liquid.
flammability		A substance made up of atoms of two or more different elements joined by chemical bonds.
scienctificnotation		A change of matter from one form to another without a change in chemical properties.
puresubstance		The smallest unit of a substance that keeps all of the physical and chemical properties of that substance.
weight		A prescribed decimal place that determines the amount of rounding off to be done based on the precision of the measurement.
technology		The ratio of the mass of a substance to the volume of the substance.
meltingpoint		Describes two or more liquids that can dissolve into each other in various proportions.
mass		A summary of many experimental results and observations; tells how things work.
accuracy		Anything that has mass and takes up space.
scientifictheory		The ability and willingness to assess claims critically and to make judgments on the basis of objective and supported reasons.
physicalproperty		The smallest unit of an element that maintains the properties of that element.
boilingpoint		An explanation of some phenomenon that is based on observations, experimentation, and reasoning.
precision		A series of steps followed to solve problems, including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions.
science		___is observing, studying, and experimenting to find the nature of things.
element		A change that occurs when a substance changes composition by forming one or more new substances.
volume		The ability of a substance to react in the presence of oxygen and burn when exposed to a flame.
heterogeneous		A sample of matter, either a single element or a single compound, that has definite chemical and physical properties.
miscible		A measure of the amount of matter in an object.
scientificlaw		A combination of chemical symbols and numbers to represent a substance.
