INTRODUCTION

Yerkes in winter
The Yerkes Winter Institute is a three-day immersion program that allows students to explore one topic in depth. This year the topic was Sound, which built upon the autumnal laboratory investigations. The students rotated among three interconnected daytime experiments, made nighttime observations, and shared their investigations with parents, siblings and younger students who joined us at the end of the institute.  [photos of parents and closing]

The Yerkes environment provides a great contrast to the urban environment of Chicago. The institute is also a learning experience for the instructors. For example, by pairing classroom teachers with researchers, each partner can learn from the other's complementary skills.
 

DAYTIME EXPERIMENTS String Telephone Lab


Students investigated how sound is transmitted by learning about the nature of a mechanical longitudinal wave.  [more photos]
 
Phonographs & Speakers Lab

Students in the phonographs and speakers lab
Students constructed gramophone-like devices to listen to vinyl recordings, examined records and "styluses" with a microscope, and inspected commercial speakers to explore how the entire complexity of music is made via one-dimensional motions.  [more photos]
 
Musical Strings Lab

Students developed a qualitative understanding of the first and second laws of strings: frequency is inversely proportional to length and directly proportional to tension. They then applied this knowledge to make strings of different lengths and tensions sound the same.  [more photos]
 

NIGHTTIME OBSERVATIONS

24-inch telescopeWhen weather permitted, nighttime observations were made with Professor Kyle Cudworth and the 40" refractor and with Professor Ed Kibblewhite and the smaller 24" telescope. This gave students the thrill of using a research-grade telescope and an appreciation for the grand scales of science.
