Thanks to google image for all the graphics and my physical science
coworkers (YOU ARE THE BEST) for all the ideas, support and help!
Science versus Technology
• System of knowledge and methods
used to find out
• Application of knowledge
hypothesis=educated guess

experiment=testing
hypothesis, test only one
variable at a time
• Manipulated variable (Independent
IV) = causes a change in another
• Responding variable (Dependent DV)
= the variable that changes in
response to the manipulated variable
For example, to find out if your heart rate depends on
exercise, you could do different amounts of exercise
(the manipulated variable) and measure the heart rate
(the responding variable).
SCIENTIFIC THEORY
versus
SCIENTIFIC LAW
• Theory=an Explanation based
on many observations &
experiments (explains why
things work the way that they
do)-also predicts what we may
see in future
SCIENTIFIC THEORY
versus
SCIENTIFIC LAW

• Law=“rule of nature” Evidence
summed up by related
observations to describe a pattern
found in nature/universe.
GUESS-for word problems
• G= Given, identify the given information
• U= Unknown, identify the unknown, what are you
trying to solve for?
• E= Equation, what equation should you use to solve
the problem?
• S= Substitute the numbers in for the letters in the
equation
• S= Solve, plug in the calculator, chug get

Kinetic Theory of Matter
thank you Mrs. Clayton-you rock!

• more kinetic energy = more movement by
particles = higher temperature

Low energy=particle   Medium energy = particles   High energy = particles
vibrate               move over & around          completely independent

CP-ability to undergo a CC
•Ex: Flammability
is the ABILITY to
burn (property)

not actually being
on fire (change)
