摘要:

We all know how hard it is to cure student misunderstandings. A mind convinced against its will is of the same conception still. Then there are the misconceptions that we adults have.

摘要:

We offered our students an opportunity to earn bonus points by demonstrating their knowledge of standing waves. The project we developed involves constructing a set of wind chimes in which each hanging rod produces a clear tone, and the combination of rods generates a chord.

摘要:

This note describes a simple and inexpensive method of designing and constructing a musical instrument. Often teachers of the physical sciences are called upon to advise students who are designing musical instrument prototypes. This article discusses the relationship between frequency and tube length for hollow metal tube chimes. A method is explained by which a set of chimes may be designed and constructed so that they cover all standard tones for a range of one or two octaves. The cost of materials will range from $3 to $6.
