Strand 1: Properties and Principles of Matter and Energy
2. Energy has a source, can be transferred, and transformed into various forms
but is conserved between and within systems
Major Objectives IS Suggested Activities Suggested Assessments
Concept A: Forms of energy have a source,
a means of transfer (work and heat) and a
receiver
a. Recognize that sound travels through
different mediums (i.e., air, water, solids).
C1

R
a. Using a variety of materials, with a partner,
students will be given opportunities to
explore sound traveling through different
mediums (i.e. tuning fork vibrating in water,
string telephone, etc.). (1.2; 3.3)
a. Students will illustrate two pictures showing
how sound travels through two different
mediums.
b. Describe different ways to change the
pitch of a sound (i.e., changes in size such
as length or thickness and in
tightness/tension of the source).
C8
C10
b. Students will experiment with various
instruments to determine changes in pitch
(due to thickness/thinness of guitar strings,
levels of water in bottles, different lengths of
straw horns, etc.). (1.3; 3.3)
b. Using a shoe-box guitar, students will
demonstrate which string will make the
highest pitch and which will make the lowest
pitch.
c. Describe how the ear serves as a receiver
of sound (i.e., sound vibrates eardrum).
C3
T
c. Using a model or diagram of the inner ear,
students will identify the tiny bones and
eardrum that vibrate to cause sound. (1.5)
c. Given a diagram of the inner ear, students
will identify and label the parts that serve as a
receiver of sound (i.e. tiny bones and
eardrum).
