• What is conduction, convection and radiation?
• If you complete the review:
• Answer questions on p332
• #27, 28, 30-34 36, 39, 47-51
• P334, 1-3 7-12, 16
• What is conduction, convection and radiation?
• They all transfer energy
• Conduction: is the transfer of thermal energy by
collision between the particles that make up
matter. It occurs because particles that make up
matter are in constant motion.
• Convection: is the transfer of thermal energy in
a fluid by the movement of warmer and cooler
fluids.
• Radiation: is the transfer of energy by
electromagnetic waves, such as light and
microwaves. These waves travel through space
even when matter is not present

Air cooled above a body of water lowers and
moves inward to a body of land

Write these definitions in your notes
• Plane mirror: flat smooth mirror
• Concave mirror: surface curves inward
• Convex Mirror: mirror that curves outward,
like the back of a spoon
• Convex lens: lens that is thicker in the middle
than at the edges.
• Concave lens: lens that is thinner in the
middle and thicker at the edges.
• IPC 2nd period. Practice putting books away
IPC warm up
• Newton’s 1st law of motion states that an object stays
at rest unless a _______ acts on it.
• a. a balanced forces
• b. a frictional forces
• c. a gravitational force
• d. an unbalanced force
Which of the following objects has the greatest inertia?
• a) a baseball
• b) a bowling ball
• c) a table tennis ball
• d) a golf ball
• Newton’s 1st law of motion states that an object

• a. a balanced forces
• b. a frictional forces
• c. a gravitational force
• d. an unbalanced force
• Which of the following objects has the greatest
inertia?
• a) a baseball
• b) a bowling ball
• c) a table tennis ball

Mirror foldable
• Fold paper in half length ways (long like a hot
dog) write
• Plane Mirror on the far left
• Concave Mirror in the middle
• and Convex Mirror on the far right
• Unfold the paper and cut in between each
mirror section to the fold line.
• Write the definition of each under the word
and write notes from the book about each.
• Several singers such as Ella Fitzgerald and
Enrico Caruso, have broken crystal glasses by
loudly singing a notes at a specific frequency.
Write a short paragraph as to how or why do
you think this happens
• The frequency of the singers voice matches
the natural frequency of the glass, causing it
to resonate. If the glass vibrates too much, it
will shatter.

• SEMESTER EXAM REVIEW WARM UP
• What is velocity?
• What is acceleration?
• What is velocity? Velocity is speed with
direction. It is a vector.
• What is acceleration? Acceleration is change
in velocity. How fast/slow an object is
speeding up/slowing down.
IPC warm up
• Review for semester exams:
• What is a vector?
• What is a scalar?
• What is a vector? Magnitude and direction
• What is a scalar? A number, magnitude
