解開玻璃杯的音樂魔法:六年級的獨立研究The music in a glass: a sixth-grade research project

研究報告的署名是「研究者:60610 吳哲宇,指導老師:藍清淵老師」。動機寫在第一段:有一次爸爸看到他隨手拿一支筆、一把尺做出簡易的樂器,嚇了一跳,就叫他彈一首歌。

他排了十二個高腳杯,用鐵棒和木棒敲,量水佔杯子多少時會是 Do、Re、Mi,再把水換成醬油、油、醋、牛奶、豆漿、綠茶和可樂,最後試膠狀的果凍蠟和冰塊。結果表裡有一句:可樂倒到水的 Mi 那個高度時音差不多,倒到 Re 那個高度時就差很多。

資料夾裡的檔案從 2006 年 10 月 3 日的研究動機、11 月 9 日的研究方法,到 2007 年 4 月 25 日的實驗影片。

簡報一共 30 頁,下面挑 10 頁。結果表寫水倒到杯子的 83% 是 Do、72% 是 Re、50% 是 Mi,聲波圖是用 GoldWave 量的。

The report is signed “Researcher: 60610 Che-Yu Wu; advisor: Mr Lan Ching-yuan.” The motive is in the first paragraph: his father once watched him make a simple instrument out of a pen and a ruler, was startled, and asked him to play a song on it.

He lined up twelve goblets, struck them with a metal rod and a wooden one, and measured how full a glass had to be to sound Do, Re and Mi; then he swapped the water for soy sauce, oil, vinegar, milk, soy milk, green tea and cola, and finally tried jelly wax and ice. One line in the results table: filled to water's Mi, cola sounds about the same; filled to water's Re, it is well off.

The files in the folder run from the motive dated 3 October 2006 and the method dated 9 November 2006 to experiment videos from 25 April 2007.

The slide deck runs to 30 pages; ten are shown below. The results table puts Do at 83% full, Re at 72% and Mi at 50%; the waveforms were measured in GoldWave.
