ASSESSMENT WHAT TO LOOK FOR
RELATED COMMENTS/QUESTIONS
Children will explore by playing the cans.

Teachers should not interrupt too soon with
questions or comments. Allow a sufficient
amount of time for free exploration.

Children will notice that the cans have different
sounds. Do these two cans sound the same or differ-
ent? Can you find the cans that sound the
same? Different?
Some children will draw a relationship between
the size of the can and its relative pitch.

Is there a reason that this can makes a higher
sound? Lower sound? Lang wants to play the
one that sounds the lowest. Help him find that
can. Some children will create patterns with the
cans. I’ll try your pattern. High, high, low; high, high,
low; high, high, low. Try mine.

ELEMENTS OF SCIENTIFIC INQUIRY
Hypothesize: Some children may incorrectly
hypothesize that the biggest can will make the
loudest sound or the smallest can will make the
softest sound.

Experiment: Children will tap, rub, and shake
the cans to make a sound. Some children may
use their hand instead of the mallet to make
a sound. Children will tap harder/softer and
faster/slower on the cans.

Observe: Children will observe that larger cans
produce different sounds from smaller cans.

Communicate: Children may invent patterns
for others to follow or follow patterns made by
others. Compare: Children will compare the sounds of
the cans to determine whether they sound alike
or different.
