form various substances.
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

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
