S8P2. Students will be familiar with the forms
and transformations of energy.
a. Explain energy transformation in terms of the Law of
Conservation of Energy.
b. Explain the relationship between potential and kinetic
energy.
c. Compare and contrast the different forms of energy
(heat, light, electricity, mechanical motion, sound)
and their characteristics.
d. Describe how heat can be transferred through matter
by the collisions of atoms (conduction) or through
space (radiation). In a liquid or gas, currents will
facilitate the transfer of heat (convection).
S8P2A - Explain energy transformations in terms
of the law of conservation of energy
• Label the following pictures with the type of energy used and created.
Type your answers in the boxes
Explain why this flow chart does not follow the law of conservation of energy.
b. Explain the relationship between potential
and kinetic energy.
Using the “Insert” tab and “shapes” selection, create bars that complete the bar graph to
show the percentage of each PE and KE for each point.
c. Compare and contrast the different forms of energy (heat, light,
electricity, mechanical motion, sound) and their characteristics.
sound
Moving
electrons
Travels as an
EM wave
Moves along
conductors
Does not require
a medium
Can be from
elastic PE
Also called
radiant
energy
Can be from
gravitational
PE
Can be static
or current
Will transfer
until it meets
equilibrium
Transfers by
conduction,
convection or
radiation
Requires a
medium
Travels as a
transverse,
mechanical
wave
Moves from
areas of hotter
to colder
Total KE and
PE in a system
light
heat
Mechanical
motion
electricity
Directions: Organize the
pictures, titles and details
into a chart. Each type of
energy has three details
that match. (You can
delete these directions
because you will need
this space.)
Has a pitch
and loudness
d. Describe how heat can be transferred through matter by the collisions of
atoms (conduction) or through space (radiation). In a liquid or gas, currents
will facilitate the transfer of heat (convection).
• Type the correct type of heat transfer in the
box. (Conduction, Convection or Radiation)

S8P4. Students will explore the wave nature of
sound and electromagnetic radiation.
a. Identify the characteristics of electromagnetic and
mechanical waves.
b. Describe how the behavior of light waves is manipulated
causing reflection, refraction diffraction, and absorption.
c. Explain how the human eye sees objects and colors in
terms of wavelengths.
d. Describe how the behavior of waves is affected by
medium (such as air, water, solids).
e. Relate the properties of sound to everyday experiences.
f. Diagram the parts of the wave and explain how the parts
are affected by changes in amplitude and pitch.
Move the terms and descriptions into the
correct locations on the Venn Diagram.

answer the questions below
Explain how each color of light is different from the
next.
Explain why the person sees this apple as red.
Describe how the behavior of waves is affected
by medium (such as air, water, solids).
Erase the question and answer
the question by restating it.
1. In what state of matter
does sound travel the
fastest?
2. In what substance does
sound travel the slowest?
3. Using the chart. Why do
you think that your voice is
a higher pitch when you
breath in helium?
