SCIENCE REVIEW
BY: KATIE PRATT
Today I will be reviewing topics from previous times this year.
WAVES
What is a wave?
A wave is a disturbance that transfers
(carries) energy from one place to
another.
WAVES
What are the two types of waves?
Electromagnetic
Mechanical
What are the two types of movement?
Transverse
Longitudinal
ELECTROMAGNETIC WAVES:
TRANSVERSE
Which wave is a transverse wave?
TRANSVERSE WAVES
wavelength
What are the parts of the transverse wave?
crest
amplitude
trough
Resting position
MECHANICAL:
LONGITUDINAL
Which wave is a longitudinal wave?
MECHANICAL WAVES
What are the parts of the mechanical waves?
wavelength
rarefaction
Compression/Amplitude
THE ELECTROMAGNETIC SPECTRUM
What are the waves on the electromagnetic spectrum from longest
to shortest?
EM SPECTRUM
What does each wave do?
Radio waves:
Radio waves are the wave with the
longest wavelength and lowest
frequency. A radio receiver
converts radio waves into
soundwaves that you can hear.
Microwave:
Inside a microwave oven, water
molecules in food absorb
microwaves, causing the food to
get hot.
Infrared waves:
Infrared rays produce
heat, so are often called
heat rays.
Visible light:
You can see visible light.
Depending on the
wavelength, certain
colors are produced.
Ultraviolet rays:
UV lamps are often used
to kill bacteria. Small
doses of UV are beneficial
to humans. Many insects
can see ultraviolet light.
X-rays
X-rays can penetrate most
matter. To take pictures of the
human body. They are also
used to take pictures of objects
used in industry and
engineering.
Gamma rays
Gamma rays have the shortest
wavelengths and highest
frequencies of the EM
spectrum. They are the most
penetrating of all
electromagnetic waves. Some
radioactive substances produce
gamma rays. They are used in
medicine in radiation therapy
to kill cancer cells.
EYES
Can you label the parts of the eye?
(skip 6)
1: cornea
2: iris
3: pupil
4: lens
5: retina
7: optic nerve
EYES
What does each part do?
Cornea:
The clear outer protective layer
of the eye.
Iris:
Colored ring of muscle that
controls how much light enters
the eye.
Pupil:
Black hole in the eye
where light enters.
Lens:
After light enters the
pupil it bends through
the lens and forms an
upside down image.
Retina:
Lining of cells when the upside-down
image is projected (contains rods &
cones where color is distinguished)
Optic Nerve:
Nerve that carries and process the
image right side up so the brain can
understand.
TRANSPARENT, TRANSLUCENT, AND OPAQUE
What are transparent, translucent, and opaque?
Transparent:
A transparent object passes/
sends light.
Examples:
• Glass
• Plastic
• Glasses
Translucent:
A translucent object
scatters light everywhere
it passes through.
Examples:
• Prism
• Lamp shade
• Stain glass window
Opaque:
Light doesn't go through
an opaque object.
Examples:
• Tree
• Rock
• bug

•The three light sources are ________,
________,
and ____________.

reflect
•Black objects __________

MATTER VOCAB
Give me the word from the definition.
Anything that has
mass and volume:
Matter
Smallest particles
that compose
(make up matter)
Atoms
These are made
up of atoms
which make up
matter.
Element
Formed when 2 or
more elements
combine.
Molecule
Smaller pieces
of anything,
part…
Particles
MATTER VOCAB CONTINUED…
To get larger in size,
volume or quantity.
Expand
A rapid back
and forth
Heat energy;
motion
energy that an
Vibrate
object has due to
the motion of its
particles
Thermal energy
Any of the forms or
states in which matter
can exist; solid, liquid,
gas
Phase
The change of a
material or mixture
from one state of
matter to another.
Change in phase
SOLIDS, LIQUIDS, GASES
Solids:
• Have a definite volume and
shape.
• Atoms are packed tightly
together.
• Its atoms do vibrate but this
movement is very small and
very rapid.
• When heat is added a solid
can become a liquid.
Liquids:
• Have definite volume but
no definite shape.
• Like solids their particles
touch but are able to
around a little more.
• They take the shape of
their container.
• When heat is added a
liquid can become a gas.
Gases:
• Have no definite volume
or shape.
• If unconstrained gases
will spread out
indefinitely.
• Confined they will take
the shape of their
container.
EVEN MORE MATTER VOCABULARY…
1. The relationship of mass
to volume. The formula is
m/v=d.
2. Measures the amount
of matter in your
substance using grams.
3. The amount of space an
object takes up. Measured
using a ruler, or measured
using water displacement.
4. The temperature at
which a liquid boils. Also
the same temperature at
which a gas condensates.
5. The temperature at
which a solid melts.
Also the temperature
at which a liquid
freezes.
6. A change that
affects the appearance
but not the substance
itself. Examples are ice
melting, tearing paper,
and breaking a pencil.
7. A change that causes
a new substance to
form. Examples are
burning wood,
fireworks, and rusting.
8. A kind of matter
that can not be
separated into other
kinds by any process
(pure elements and
compounds).
10. A property that stays
consistent, it`s not going
to change based on the
amount of matter.
Examples are density,
melting point, boiling
point, and solubility.
9. The ability of one
substance to dissolve
into another. The
solute is what is
being dissolved. The
solvent is what is
dissolving the other
substance.
11. A property that can
change depending on the
amount of matter. Examples
are volume, mass and weight.
