What was not expected, however, was the temperature of the water. Do you know how shocking putting your tender and vulnerable ear under cold water can be?
April 28, 2010
On this co-op day, we performed a science experiment about how sound waves travel in different substances. Two spoons were tied in the middle of a string so that they can clang together easily. Then, the silverware, the students, and their ears underwent a series of stages where we had to listen to the different tones of the ringing spoons under different conditions. I won't go into details, but one of these stages was to submerge our ears into a bucketful of water and listen to the also-submerged spoons tinkling. We were not looking forward to this part and kept the towels nearby.
