Cow's Eye Dissection:  Cow's Eye Dissection (Clip)
Running Time:
00:07:58
How does your eye work? You see the world because light gets into your eyes. Your eye uses that light to make an image of the world inside your eye—just as a camera uses light to make a photograph. At the Exploratorium, we dissect cow eyes to show people how an eye functions, and look at the parts that make up an eye. This video shows and explains a dissection with one of our staff Explainers.

Science of Music:  Tuning (Clip)
Running Time:
00:03:07
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.

Science of Music:  Stepping (Clip)
Running Time:
00:02:48
Stepping is rhythmic movement that uses the hands and feet as an instrument. Known best among African American fraternities and sororities, stepping draws on a long African tradition of using the body to make music. Synchronized movement and chants are coordinated by the leader, or step master. Sometimes improvising, always cultivating their own distinctive moves and rhythms, step teams reflect and reaffirm both the unity and the unique style of their group.
