Chemistry

100

This type of paricle is like an atom but it has an imbalanced number of protons and electrons

Ion

200

This type of chemical reaction follows the general formula:

AB --> A + B

Decomposition Reaction (D)

300

The name of the compound produced in the synthesis reaction between diatomic oxygen and magnesium metal

Magnesium oxide

400

This ionic compound can be written as:

CuO

(What is its name?)

Copper (II) oxide

(BONUS POINTS FOR GETTING THE ROMAN NUMERALS!)

500

This is the name of the salt produced in the acid-base neutralization reaction between hydrobromic acid (HBr) and sodium hydroxide (NaOH):

Sodium bromide (NaBr)

Nuclear Energy

100

This is the amount of time it takes for 50% of a radioactive isotope to decay

Half-life

200

This type of subatomic particle varies between different isotopes of any given element

Neutrons

300

This type of nuclear reaction is not practically usable by humans but is readily occuring within the Sun (and other stars); it creates heavier nuclei from lighter ones

Nuclear fusion

400

This number is obtained by taking the sum of the mass of all nucleons (particles that make up the nucelus) of any given isotope

Mass number

500

This type of nuclear decay results in an increase in the atomic number of the parent isotope

Beta decay

Biology

100

These are different versions of a gene

Alleles

200

This process describes heritable changes in populations over many generations

Evolution

300

This type of genetic drift occurs when a few individuals of a species are the first to "settle" a new habitat

The Founder Effect

400

Human blood types display this particular pattern of inheritance

Codominance

500

Organisms with this type of characteristic are more likely to survive and reproduce

Selective advantage

Physics

100

This force is considered when calculating the potential energy of an object some height above the ground

Gravity

200

This type of quantity has magnitude but not direction

Scalar quantity

300

This is calculated by considering displacement over time

Velocity

400

This type of energy relates the mass and velocity of a moving object

Kinetic energy

500

This is equal to the slope of a velocity-time graph

Acceleration

Cosmology

100

Ancient civilizations recognized that these groups of stars appear to resemble familiar shapes like animals and heros

Constellations

200

This theory is our best scientific explanation for the beginning of the universe

The Big Bang Theory

300

This type of number is used to express very big or very small numbers in science

Scientific notation

400

This so-called "law" describes the observation that distant galaxies seem to be moving away from us

Hubble's Law

500

These stretched out light waves appear all across the universe when radio-telescopes are aimed deep into space; this radiation is thought to be from the very early universe

The Cosmic Microwave Background (CMB)
