Earth/Space Physics Test 1 Review

A set of vocabulary flashcards reviewing key concepts, measurement units, statistics, and scientific method principles from the Earth/Space Physics Test 1 review.

Scientific method order

The sequential steps of the scientific method listed as observation, question, hypnosis, experiment, conclusion, and results.

Units in measurements

Standard units (such as meters or inches) that help provide clarity and accuracy in measurements (e.g., $6\,\text{ft}$).

Independent variable

The cause that acts alone in an experiment (e.g., Mariah studying 15 minutes a day to improve math skills).

Dependent variable

The effect that depends on the independent variable (e.g., Mariah's math skills getting better after 3 months).

Closed system

A system type where matter is trapped on Earth, but energy can flow in and out.

Earth's system features

Unique characteristics of Earth's system, including that Earth has lids, a lot of water, oxygen, and an atmosphere.

Mode

The value that appears most frequently in a dataset (e.g., $7$ in the set $8, 7, 9, 5, 7, 2$).

Mean

The average of a set of numbers (e.g., for the set $3, 4, 5, 9, 2$, the mean is $4.6$, which rounds up to $5$).

Range

The difference between the maximum and minimum values in a set of numbers (e.g., $9 - 1 = 8$ for the set $4, 2, 3, 6, 9, 8, 1$).

Slope of a position vs time graph

The slope feature on a position vs time graph that represents an object's velocity.

CER

A scientific reasoning framework standing for Claim, Evidence, and Reasoning.

Centimeters

The best unit of measurement among seconds, grams, kilometers, and centimeters to use when measuring the length of a table.

Kilograms

The best unit of measurement among centimeters, kilograms, and meters to use when measuring the mass of a dog.

$$3.5 \times 10^6$$

A number written in scientific notation that converts to $3,500,000$ in standard form.

$625,000$ in scientific notation

The number $625,000$ expressed in scientific notation as $6.25 \times 10^5$.
