Pipes of Pan

The exhibit uses the principle of resonance to separate sound
into individual frequency components. Each pipe is resonant at
a certain frequency, which is determined by its length.
Since each pipe has a different length, each pipe selects a
specific set of frequencies and ignores the other frequencies.

Watch Me Pedal

Do your legs move like the same way as Kelly? When you
pedal the bike these parts of the skeleton move:  1) bone
of the upper leg, 2) bones of the lower leg, and 3) bones
of the feet. The same bones move in your body.

Come Race with Me

Ms. Elma Muros-Posada can run 10 meters in 1.2 seconds.
Can you run as fast as Elma? Position yourself at the starting
line like Elma at the end look at your speed on the LED screen.
There are over 630 muscles in your body that enable you to
breathe, eat, talk, walk, and even run fast.

Lift Yourself

Stand at the center of the platform and hold on to the
rope with both hands. Gently pull on the rope and try
to lift yourself and the platform. This exhibit is an example
of a compound pulley system called a block and tackle.
A block and tackle is an arrangement of rope and pulleys
that allow you to trade force for distance.

Stereo Hearing

Put one end of the hose close to your ear, and then close
your eyes. Your friend will slightly tap the hose at different
parts. Can you easily guess where the hose is tapped each
time? If the hose is tapped at the middle while you are listening with both ears, you perceive the sound source to be in front
of you or directly behind you. If the hose is tapped on the left
side, you perceive the sound to be coming from the left. If it
is tapped on the right side, the sound seems to be coming
from the right.
