Earth Science
Earth's structure and composition, as well as the processes that change Earth, such as volcanic and seismic activity.
astronomy
The study of the moon, stars, and other objects in space
Science
An organized way of gathering and analyzing evidence about the natural world.
Precision
a measure of how close a series of measurements are to one another
SI
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.
physical science
the sciences concerned with the study of inanimate natural objects, including physics, chemistry, astronomy, and related subjects.
life science
the study of living things
controlled experiment
An experiment in which only one variable is manipulated at a time. Or a condition that is being held constant
independent variable
what is being changed
dependent variable
what is being measured
control
In an experiment, the standard that is used for comparison
Observational experiment or study
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
a research investigation carried out in a naturally occurring setting
laboratory study
Research done in a laboratory
Physical Model
A physical representation of an object. Prototypes and appearance models are physical models.
conceptual model
a verbal or graphical explanation for how a system works or is organized
mathematical model
one or more equations that represent the way a system or process works
Hypothesis
A testable prediction, often implied by a theory
Theory
A hypothesis that has been tested with a significant amount of data. Explains why something happened.
Law
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
Information obtained through the senses.
evidence
proof
Data
Facts and statistics collected together for reference or analysis
Big Bang Theory
Cosmological model that explains the sudden development of the universe through expansion from a hot, dense state.
plate tectonics
A theory stating that the earth's surface is broken into plates that move.
atomic theory
a theory that states that all matter is composed of tiny particles called atoms.
gram
a metric unit of mass equal to one thousandth of a kilogram.
meter
The meter is the basic unit of length in the SI system of units. ... The previous definition of the meter was one ten-millionth of the distance from the geographic north pole to the equator, measured over the earth's surface in a circle running through Paris, France.
second
SI base unit for time
Celsius
Metric unit for measuring temperature; On this scale water freezes at zero and boils at 100.
Kelvin
The SI base unit of temperature
liter
Basic unit of volume in the metric system
Metric Prefixes
Giga, Mega, Kilo, deci, centi, milli, micro, nano
derived unit
A unit defined by a combination of base units
direct relationship
a relationship in which one variable increases with an increase in another variable
inverse relationship
a relationship in which one variable decreases when another variable increases
Speed
The distance an object travels per unit of time
Velocity
Speed in a given direction [Show Less]
