Peter D'Amato of California Carnivores gives us a guided tour of the Venus Flytrap, one of the world's best-known carnivorous plants. If you’ve ever gone to hear an orchestra play, you know that the performance begins only after a session of tuning. An oft-repeated story tells of a visiting foreigner attending a concert in Paris. Afterwards, when asked which part of the performance he liked best, he replied, “The beginning, just before the man with the stick came in.”
Tuning means adjusting the pitch of an instrument. The pitch of a sound depends on its frequency, the number of vibrations per second that produce the sound. For example, plucking a cello string might cause it to vibrate back and forth 200 times each second. You hear that sound as a low pitch of 200 cycles per second, or 200 hertz.
An orchestra tunes itself to a very particular frequency, usually 440 hertz, a note known as A 440. The note is played by the oboist, and the rest of the orchestra tunes their instruments to match it. The oboe leads the tuning because of all the instruments, it is least affected by humidity or other weather conditions. Music is more than meets the ears directly. Just as no sound exists in a vacuum, every space sculpts the sound within it. Like a site-specific equalizer, reflections, absorption, and resonances combine to give each venue a unique acoustic stamp.
A subway tunnel is “live” space, rich with reverberations that trap and reflect sound in a well of hard tile. True to their name, “dead” spaces do nothing: The only sound heard is what travels directly from instrument to ear. An open field is the ultimate dead space.
As you follow this wandering riff, listen to the changes wrought by environment. Distance is also a factor here—the sound you hear is recorded from the camera’s vantage. Which spaces sound live? Which sound dead? Do the acoustic changes affect the feeling of the music?
Saxophonist Michael Pearce plays with the Highwater Blues Band in the San Francisco Bay Area. Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. In this zany competition teachers will have ten minutes to create a science activity. This week’s “secret” ingredient- carbohydrates! A series of sometimes fiery demonstrations shows what the pressure and composition of Venus’s atmosphere are like. This program was presented in conjunction with the Exploratorium’s webcast of the 2004 transit of Venus. Astronomers in many parts of the world watched as Venus moved across the disk of the Sun, one of the rarest planetary alignments. The Exploratorium webcast this historic event from Greece.

Watch as Exploratorium staff and local teachers compete for the title of Iron Science Teacher. Each contestant has 10 minutes to make a science lesson out of a secret ingredient. In this special Halloween edition, today's secret ingredient is: Plastic Bags! Produced by students from San Francisco's Aim High Program. Today they ask, how do our ears work? Can we communicate without words? How do whales communicate under water? Why don't bats slam into trees as they fly? Middle school students will interview Exploratorium Educator Ken Finn and Biologist Dr. Karen Kalumuck, plus special surprise guests! On November 15th, 1999, for the first time in 25 years, the planet Mercury passed between us (in the western hemisphere) and the sun--an event known as a "transit." Here is one of five short streaming videos detailing the event.
