Questions and Answers
physics
Ans: the study of forces, energy, motion
Chemistry
Ans: study of atoms and molecules, their structures, and their
interactions to form various substances.
Earth Science
Ans: Earth's structure and composition, as well as the processes that
change Earth, such as volcanic and seismic activity.
astronomy
Ans: The study of the moon, stars, and other objects in space
Science
Ans: An organized way of gathering and analyzing evidence about the
natural world.
Precision
Ans: a measure of how close a series of measurements are to one
another
SI
Ans: is a scientific method of expressing the magnitudes or quantities of
important natural phenomena. There are seven base units in the system,
from which other units are derived. Universal for comparing data.

Ans: the sciences concerned with the study of inanimate natural objects,
including physics, chemistry, astronomy, and related subjects.
life science
Ans: the study of living things
controlled experiment
Ans: An experiment in which only one variable is manipulated at a time.
Or a condition that is being held constant
independent variable
Ans: what is being changed
dependent variable
Ans: what is being measured
control
Ans: In an experiment, the standard that is used for comparison
Observational experiment or study
Ans: studies attempt to understand cause-and-effect relationships.
However, unlike experiments, the researcher is not able to control (1)
how subjects are assigned to groups and/or (2) which treatments each
group receives. ... Therefore, a sample survey is an example of an
observational study.
field study
Ans: a research investigation carried out in a naturally occurring setting
laboratory study
Ans: Research done in a laboratory
Physical Model
© 2025 All rights reserved
, 3 | Page
Ans: A physical representation of an object. Prototypes and appearance
models are physical models.
conceptual model
Ans: a verbal or graphical explanation for how a system works or is
organized
mathematical model
Ans: one or more equations that represent the way a system or process
works
Hypothesis
Ans: A testable prediction, often implied by a theory
Theory
Ans: A hypothesis that has been tested with a significant amount of
data. Explains why something happened.
Law
Ans: A law in science is a generalized rule to explain a body of
observations in the form of a verbal or mathematical statement.
Scientific laws (also known as natural laws) imply a cause and effect
between the observed elements and must always apply under the same
conditions. Explains how it happened not why.
Observation
Ans: Information obtained through the senses.
evidence
Ans: proof
Data
Ans: Facts and statistics collected together for reference or analysis
