This number represents the number of protons in an atom.

Atomic number

100

This layer of Earth lies directly below the crust.

The Mantle

100

This is the rate at which an object changes its position, and it includes both the speed of the object and the direction of its motion.

Velocity

100

A tentative, testable statement or educated guess that proposes a possible explanation for a phenomenon or answers a specific research question

Hypothesis

200

These blood cells help fight infection.

White blood cells

200

This type of bond involves the sharing of electrons.

Covalent Bond

200

This biome is characterized by permafrost and low-growing vegetation.

Tundra

200

This quantity measures how much matter an object contains.

Mass

200

Any factor kept constant in a scientific experiment or statistical study, or a baseline group in an experiment that does not receive the experimental treatment.

Control.

300

Name at least three biological kingdoms

Any combination of plants, animals, fungi, protists, bacteria, and archaea

300

The element has the chemical symbol "Pb"

Lead

300

Name one of the two most significant "greenhouse" gases

Carbon dioxide and methane

300

This is the path followed by a projectile under gravity. Plotting a quadratic equation also yields this shape.

Parabola

300

The most commonly occurring value in a set of numbers

Mode

400

This is the maximum amount of solute that can dissolve in a solvent at a given temperature.

Solubility

400

This family of elements includes helium, neon, and argon.

Noble gases


400

This process wears away rock and soil and transports it elsewhere.

Erosion

400

This is the law stating that an object in motion stays in motion unless acted on by a net force.  

Newton's first law

400

a statistical measure that describes the strength and direction of a relationship between two variables. It indicates how closely these variables change together, but importantly, _________ does not imply causation.

Correlation

500

This is the movement of water across a selectively permeable membrane.

Osmosis

500

Who was the scientific leader of the Manhattan project? 

J. Robert Oppenheimer

500

This scale is used to describe the hardness of minerals.

Mohs hardness scale

500

This is the maximum speed reached by a falling object when air resistance balances gravity.

Terminal Velocity

500

This is the probability of getting results at least as extreme as the observed result, assuming the null hypothesis is true.

Hint:

With a value below 0.05, we consider a result statistically significant.
