QUESTIONS AND CORRECT DETAILED
ANSWERS|ALREADY GRADED A+|UPDATED
physics - Answer-the study of forces, energy, motion
/.Chemistry - Answer-study of atoms and molecules, their structures, and their
interactions to form various substances.
/.Earth Science - Answer-Earth's structure and composition, as well as the processes
that change Earth, such as volcanic and seismic activity.
/.astronomy - Answer-The study of the moon, stars, and other objects in space
/.Science - Answer-An organized way of gathering and analyzing evidence about the
natural world.
/.Precision - Answer-a measure of how close a series of measurements are to one
another
/.SI - Answer-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 - Answer-the sciences concerned with the study of inanimate natural
objects, including physics, chemistry, astronomy, and related subjects.
/.life science - Answer-the study of living things
/.controlled experiment - Answer-An experiment in which only one variable is
manipulated at a time. Or a condition that is being held constant
/.independent variable - Answer-what is being changed
/.dependent variable - Answer-what is being measured
/.control - Answer-In an experiment, the standard that is used for comparison
/.Observational experiment or study - Answer-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 - Answer-a research investigation carried out in a naturally occurring setting
/.laboratory study - Answer-Research done in a laboratory
/.Physical Model - Answer-A physical representation of an object. Prototypes and
appearance models are physical models.
/.conceptual model - Answer-a verbal or graphical explanation for how a system works
or is organized
/.mathematical model - Answer-one or more equations that represent the way a system
or process works
/.Hypothesis - Answer-A testable prediction, often implied by a theory
/.Theory - Answer-A hypothesis that has been tested with a significant amount of data.
Explains why something happened.
/.Law - Answer-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 - Answer-Information obtained through the senses.
/.evidence - Answer-proof
/.Data - Answer-Facts and statistics collected together for reference or analysis
/.Big Bang Theory - Answer-Cosmological model that explains the sudden development
of the universe through expansion from a hot, dense state.
/.plate tectonics - Answer-A theory stating that the earth's surface is broken into plates
that move.
/.atomic theory - Answer-a theory that states that all matter is composed of tiny particles
called atoms.
/.gram - Answer-a metric unit of mass equal to one thousandth of a kilogram.
/.meter - Answer-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
