Chapter 1 Science Skills Test Review

Vocabulary flashcards covering scientific concepts, measurement conversions, models, laboratory safety, and SI units from Chapter 1.

Science and Technology

Fields that are related because advances in science may lead to advances in technology and vice versa.

Earth Science

A branch of science that overlaps with biology because it involves the study of systems that may include living organisms.

Atoms

The building blocks of all matter.

Hypothesis Revision

The action taken when data in an investigation does not support the original hypothesis.

Scientific Theories

Scientific explanations that are never proven.

Scientific Models

Physical or mental representations of an object or an event that help visualize things that are very complex, very large, or very small.

Most Important Safety Rule

To always follow your teacher's instructions and textbook's directions exactly.

Safe Laboratory Procedure

Practices such as tying back long hair and loose clothing before conducting an experiment.

Conversion of $15\,\text{km}$ to Meters

$$15\,\text{km} \times \frac{1000\,\text{m}}{1\,\text{km}} = 15000\,\text{m}$$

Clock Precision

Illustrated by a clock measuring to the nearest tenth of a second, which offers more data than a clock measuring only to the second.

$50^\circ\text{F}$ in Kelvins

$283\,\text{K}$ (calculated via $C = \frac{5}{9}(50 - 32)$ and $K = 10 + 273 = 283$).

Circle Graph

The type of graph used to show how a part of something relates to the whole.

SI Units

Units used by scientists who speak different languages to make their data understandable to one another.
