This book contains scaled-down versions of Exploratorium exhibits that teachers can make using common, inexpensive, easily available materials. Each topic begins with a drawing of the original full-sized exhibit on the museum floor, a photograph of the scaled-down version which contains an introduction to the exhibit, a list of materials needed…

Understanding of immunological techniques such as the Enzyme Linked Immuno Sorbent Assay (ELISA) is an important part of instructional units in human health, developmental biology, microbiology, and biotechnology. This paper describes a simple ELISA exercise for undergraduate biology that effectively simulates the technique using a paper model.…

A series of charts lists weekly activities for conducting a hands-on science laboratory in grades K-6. Arranged by grade level, the charts complement chapters in the "Gateways to Science" textbook series (McGraw-Hill, 1979). For each week, a concept to be explored is tagged to a 45-minute activity. This document was selected by the…

Describes an out-of-doors, partially unstructured experiment to determine the coefficient of friction for a moving car. Presents the equation which relates the coefficient of friction to initial velocity, distance, and time and gives sample computed values as a function of initial speed and tire pressure. (GS)

Describes the macroscopic process of the swelling of clay by adding water, and the corresponding microscopic process of water molecules entering the spacings between clay crystals. Discusses how the Bragg equation can be used together with other physical data to calculate these spacings. (MLH)

Discusses the advantages of using small scale experimentation in the undergraduate organic chemistry laboratory. Describes small scale filtration techniques as an example of a semi-micro method applied to small quantities of material. (MLH)

Describes an undergraduate chemistry experiment which demonstrates the use of codistillation for the separation of substances of low volatility from nonvolatiles. Pine gum is separated into turpentine and rosin by means of codistillation with steam at temperatures above 100 degrees centigrade. (MLH)
