Section Terms
These are terms (bolded and colored words) from your textbook
that were stated in the beginning of each section. Hope you payed
attention….
Physical Science
The study of
matter and
energy. It is
split into two
categories
known as
Physics and
Chemistry.
Scientific Method
A series of
steps that
scientists use
to answer
questions
and solve
problems.
Theory
A unifying
explanation for a
broad range of
hypotheses and
observations that
have been
supported by
testing.
Technology
The application of
knowledge, tools,
and materials, to
solve, problems and
accomplish tasks;
technology can also
refer to the objects
used to accomplish
tasks.
Observations
Any use of
the senses to
gather
information.
Model
A
representation
of an object or
system.
Law
A summary of
many
experimental
results and
observations; a
law tells how
things work.
Density
The amount
of matter in
a given
space; mass
per unit
volume.
D=m/V
Hypothesis
A possible
explanation
or answer to
a question.
Area
A measure of
how much
surface an
object has.
Meter
The basic
unit of
length in the
SI system.
(m)
Data
Any pieces of
information
acquired
through
experimenta
tion.
Volume
The amount
of space that
something
occupies or
the amount
of space that
something
contains.
Temperature
A measure of how
hot (or cold)
something is;
specifically, a
measure of the
average kinetic
energy of the
particles in an
object.
Mass
The amount
of matter
that
something is
made of.
Section 1
Exploring Physical Science
What did Czarnowski and Triantafyllou
create? What part of nature inspired
this idea?
 They created a boat known as the Proteus. It had two broad
paddles and two car batteries. The Proteus was designed after a
penguin and the paddles were suppose to move like the
penguins flippers.
What is physical science? What 2
categories split physical science?
 Physical science is the study of matter and energy.
 It is split into Physics and Chemistry.
What purpose do models serve?
 To demonstrate an idea, event, or object. Represent an object
or system.
 Business: graph’s, tables, charts, etc.
 Students/ Teachers: demonstrations- atoms, space, particles,
etc.
Physics or Chemistry
 When you move right and your car is turning left.

Chemistry
Energy+ Matter= Physical Science p. 7
 What do a ball, air, and a cheetah have in common?
They are made up of matter and they also have energy.
 Moving objects have energy. Do non-moving objects have
energy?
Yes
Section 2
Using the Scientific Method
True or False
 Advancements in science are mostly due to luck.





False
Scientists usually ask a question before they make any observations.
False
Scientific laws are determined by nature.
True
A scientific law is a summary of many experimental results and
observations.
True
Laws tell you why something happens, not what happens.
True
You could be arrested if you break a scientific law.
False
What is the Scientific Method?
 Scientist use the scientific method to….
 Ask questions
 Solve problems by following a series of steps
Hypothesis
 A hypothesis is…
 Usually stated in an “if…then…” format
 What is a hypothesis?
 A possible explanation or answer of a question
Analyzing, Conclusions, and
Communicating Results
 Analysis of results means doing what with the data?
organizing
 What are 3 ways that communicating results can help other
scientists further scientific research?
Scientists can- based on your results- study a new
problem, conduct their own test, or even try to learn
something more specific by modifying your test.
 What is ALWAYS true for scientific investigations?
Scientist take accurate measurements and accurately
record data.
Building Scientific Knowledge
 An idea that is supported by many tests and experiments can
become what (2 things)?
A theory or a law
 What is NOT true about a scientific theory?
It is a simple guess
Section 3
Using Models in Physical Science
True or False
 When we picture things in our minds, we are creating
models.
True
What did the MIT engineers hope to
gain from making a model?
 They hoped to gain more knowledge and a greater
understanding about a boats propulsion.
What is a model?
 Something that can represent
or
.
Systems or Objects
 What are some ways to use models in science?
looking at the tiny parts of a microscopic cell on a cell
diagram, testing a new design for a building on a
computer before spending the money on construction,
launching a homemade rocket in your backyard, observing
how the parts of matter fit together without being able to
see the tiny particles, etc.
Models Help You Visualize Information
 How could using the spring toy as a model help you
understand the behavior of sound waves?
It helps you understand the behavior of sound waves
because it shows particle will crowd together- form a
group- in certain parts of the sound wave.
Models are Just the Right Size/ Models
Build Scientific Knowledge
 Models can be used as
to illustrate
and
investigations.
Scientific ideas/objects, theories, conduct
Object
Smaller or Larger
Mount Everest
Smaller
A computer chip
Larger
The moon
Smaller
A skyscraper
Smaller
A mosquito
Larger
Now come up with 2 or 3 examples of
when the model would be larger and when
the model would be smaller.
Models can Save Time and Money
 How can cyber- crashes save time and money?
It can save time because you can find out in the cybercrash what part of the car should be fixed before
building it and wasting money adding something that’ll
just be removed later.
Section 4
Measurement and Safety in Physical Science
Beginning/ The International System of
Units
 Before you determine how many lenses will fit into a moving crate, what




must you figure out?
The volume of the crate and the volume of the lenses.
At one time, systems of measurements were based on objects that varied in
size, such as body parts and grains of barley. (true or false)
TRUE
Scientist can
and
their data when data are expressed
in SI units.
Share and compare
What unit of measurement is most practical for measuring a house?
Meters (m)
The
is the SI unit for temperature, but scientist often use
degrees Celsius.
Kelvin (K)
Derived Quantities
 What are the 2 kinds of derived quantities?
Area and Density
Descriptions
Sharp Objects
Hand Safety
Animal Safety
Plant Safety
Eye Protection
Chemical Safety
