The Scientific Method
The systematic collection and classification of data, and usually the formulation and testing of a hypothesis based on that data.
What is the Scientific Method
A fraction made up of equivalent measures, that is equal to one. It is used to convert from one unit to another.
What is Unit Multiplier?
A method of expressing extremely large or extremely small numbers, using powers of ten.
What is Scientific Notation?
Takes place in definite proportions, and results in the formation of new compounds and/or elements. It involves the breaking of bonds, and the formation of new ones.
What is Chemical Change?
The smallest unit of elements, made up of electrons surrounding the nucleus of protons and neutrons.
What is an Atom?
A collection of facts and information, which you may have recorded during an experiment, from which conclusions and decisions can be made.
What is Data?
A system of measurement based on multiples of ten and the decimal. The base unit of measurement is the meter.
What is the Metric System?
The number of digits known for certain, plus one estimated digit.
What are Significant Digits?
0 K on the Kelvin scale, it is the theoretical minimum possible temperature, at which an object would have the lowest possible kinetic energy.
What is Absolute Zero?
A molecule composed of two atoms bonded together.
What is a Diatomic Molecule?
Starts as facts and works towards general conclusions (science). It is the process of finding rules.
What is Inductive Reasoning?
The mass per unit volume of a substance.
What is Density?
A systematic study through careful observation, collection of data, and experimental investigation; observations of the physical universe.
What is Science?
When particles spread out to evenly fill a space.
What is Diffusion?
A substance made up of two or more elements chemically joined together.
What is a Compound?
Starts with general statements and leads towards specifics. It is about applying rules.
What is Deductive Reasoning?
Mass cannot be created or destroyed. For any amount of chemical or physical changes, total mass remains constant.
What is the Law of Mass Conservation?
The degree of closeness between a measured value, and its actual value.
What is Accuracy?
The thickness of a liquid.
What is Viscosity?
A mixture in which one substance made up of very small particles is dispersed throughout another substance.
What is a Colloid?
The standard in an experiment that whatever factors are being tested are not applied to.
What is the Control?
The curved surface of a liquid. It will be a convex curve if the liquid molecules have a greater attraction to themselves than the container, or a concave curve when the liquid molecules have a greater attraction to the container than each other.
What is a Meniscus?
The degree of closeness of repeated measurements. How close the results of multiple trials of something are to each other.
What is Precision?
A state of matter similar to gas, but in which the particles are moving at much greater speeds, and are electrically charged.
What is Plasma?
A heterogeneous mixture, that differs from a solution in that it contains particles that are not permanently suspended, and will eventually settle out of.
What is a Suspension?
