Pipes of Pan

Place your ear against the end of the pipes, one at a time. Listen and compare the sounds that you hear. The noise you hear is actually a mixture of sound of many different frequencies. 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. Push the button. When you hear the timer beep. RUN! At the finish line, look at your speed on the LED screen. What is your speed? 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 allows 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.
