Both experiments rises very fast. It is
can be conducted impossible to take
simultaneously; the readings
save time manually.
Less work need to be done by the students. This enable
experiment to be done in a small group; the learning
process becomes more meaningful. 20

The Reflection and Absorption of Sound
Questions
1. Study the results that you obtained.
a. What type of surfaces is good reflector
of sound?
b. What type of surfaces is good absorber
of sound?
2. You can hear the ticking sound of the clock
at the other end of the tube. Why does
this happen? 35

36. ENHANCE
The echoes in the studio can be reduced
because the sound is absorbed by soft
and rough surfaces. Name the objects in
this studio that can absorb the sound.

37. EXTENSION
The Bouncing Sound
Bats produce high-pitched beeps or clicks and
listen for the echoes of these sounds as they are
reflected off by objects. How can bat measure
the distance of and object? Plan and carry out

different distances of tube containing the sound
source (use varies distance of tube A) and record 37
