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

100

This physical property refers to the measure of the amount of matter in an object and is typically measured in grams or kilograms.  It is related to but not exactly the same as weight.

What is Mass?

100

A method of expressing extremely large or extremely small numbers, using powers of ten.

What is Scientific Notation?

100

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?

100

The smallest unit of elements, made up of electrons surrounding the nucleus of protons and neutrons.

What is an Atom?

200

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?

200

This physical property describes the amount of space an object occupies and is typically measured in cubic units.

What is Volume?

200

The number of digits known for certain, plus one estimated digit.

What are Significant Digits?

200

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?

200

A molecule composed of two atoms bonded together.

What is a Diatomic Molecule?

300

Starts as facts and works towards general conclusions (science). It is the process of finding rules.

What is Inductive Reasoning?

300

The mass per unit volume of a substance.

What is Density?

300

A systematic study through careful observation, collection of data, and experimental investigation; observations of the physical universe.

What is Science?

300

When particles spread out to evenly fill a space.

What is Diffusion?

300

A substance made up of two or more elements chemically joined together.

What is a Compound?

400

Starts with general statements and leads towards specifics. It is about applying rules.

What is Deductive Reasoning?

400

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?

400

The element symbol for Sodium?

What is Na?

400

The thickness of a liquid.

What is Viscosity?

400

A mixture in which one substance made up of very small particles is dispersed throughout another substance.

What is a Colloid?

500

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?

500

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?

500

The number of magnesium atoms in the compound 2Mg2SO4.

What is four?

500

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?

500

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?
