science
observations/experiments to gain knowledge about the world
models
not completely accurate, have limits, but are workable
scientific model
physical, mathematical, or conceptual representation of an idea
why do we study science
to learn about God’s creation
worldview
how someone observes the world around us; Secular & Christian
paradigm
beliefs that control how someone perceives an aspect of reality
naturalistic paradigm (naturalism)
the nature of human existence; believe that natural laws & forces operate the world
uniformitarianism
everything that happened now has happened in the past; supported by natural. para.
uniformity
repeated experiments under the same circumstances
scientific method
method of procedure that has characterized science since the 17th century
scientific theory
explanation of something that has happened in the world around us, has to be repeatedly tested by scientific method
scientific law
the description of a fact, completely accepted by the scientific community
theory
explains the “how and why”, can change
law
explains the “what”, never changes
imperical/operational/dominion science
present day observations/experiments
historical science
attempts to piece together past events in order to explain them
classical physics
1600 to 1900; almost everything we use today
modern physics
1900 to present; new discoveries, both are still used today
electromagnetism
study of electricity & magnetism, very similar
thermodynamics
physics of heat, temperature, & energy
kinematics
how objects move
dynamics
explains cause of motion
applied physics
application of physics to solve scientific/engineering problems; a bridge between both
independent variable
the variable you change/manipulate
dependent variable
the variable that is measured, stays the same
controlled variable
variables kept the same for both groups
astrophysics
combines astronomy & physics; concerned with the physical nature of stars & other celestial bodies
geophysics
combines biology & physics; concerned with the physical properties of the Earth and its surrounding space environment
atmospherephysics
studies Earth’s & other planet’s atmosphere; meteorology
nuclear & high energy physics
investigates the ultimate structure and particles of matter
Issac Newton
developed kinematics & dynamics;
kinematics & dynamics are…
the basis for most comprehensive scientific laws in history
mechanics
combination of kine. & dyna.; how forces affect motion & describes motion in lines, arcs, & circles
Benjamin Franklin
the first to assign positive & negative terms to an electric charge
hypothesis
a scientists assumption/explanation made on the basis of limited observations
bias
disproportionate weight in favor of or against something; influences hypotheses
objective
to be separate from personal bias
experiment
a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact
controlled experiment
experiment done under controlled circumstances
