Explains a physics experiment on the dynamics of impact cratering. Measures the spreading velocity of the impact wave and the acoustic signal. (YDS)

Describes a laboratory experiment on surface tension. (Contains 14 references.) (YDS)

Toilet paper (TP) composition and physical characteristics were used to model scientific investigations that combined several "National Science Education Standards." Experiments with TP permitted the integration of TP history, societal change resulting from invention, mathematics (including geometry and statistics), germ theory, and personal…

All animals must make choices regarding what foods to eat, where to eat, and how much time to spend feeding. Optimal foraging theory explains these behaviors in terms of costs and benefits. This laboratory exercise focuses on optimal foraging theory by investigating the winter feeding behavior of birds on the goldenrod gall fly by comparing…

These units were produced by a team exploring the possibility of developing some of the basic concepts of mathematics through simple, but significant physical science experiments. The purpose of the entire project is to see if learning and understanding of mathematics can be improved by the use of these science-related units in mathematics…

Describes the use of analysis of rotational faults in undergraduate structural geology laboratories to provide students with applications of both orthographic and stereographic techniques. A demonstration problem is described, and an orthographic/stereographic solution and a reproducible black model demonstration pattern are provided. (TW)

Discusses the use of a computer software package called ASYST for general laboratory computing. Describes the software's capacity for acquiring data in a flow injection analysis experiment. Reviews the series of commands used by students in carrying out the experiment. (TW)

Describes a spectrophotometric titration experiment which uses a manual titration spectrophotometer and manually operated buret, rather than special instrumentation. Identifies the equipment, materials, and procedures needed for the completion of the experiment. Recommends the use of this experiment in introductory quantitative analysis…

Describes an experiment that demonstrates the use of HPLC in simultaneous multi-element analysis. Discusses the application of this process in identification of steels and trade effluents. (TW)

Describes a physical chemistry experiment which uses spectroscopy to measure the heat of formation of Na2SiF6. Discusses the opportunities for students to see the use of a familiar instrument in an unfamiliar application, emphasizing that there are often many ways to attack problems in science. (TW)

Describes a year long laboratory program for third, fourth, and fifth graders. States the goal of the program is to demonstrate what chemistry is, how it is done, and why it is fun and interesting. Provides a syllabus of the experiments and lists educational objectives. (MVL)

Demonstrates a laboratory to teach the concept of moment of inertia in which students are asked to identify four objects of equal mass sealed in unopenable containers by identifying the mass distribution of each object. Gives instructions to build an instrument to determine relative distribution of mass. (MDH)

The effectiveness of science experiments often are partly dependent upon the amount of classroom time available for implementation. This factor alone has frustrated many teachers who attempt to complete laboratory assignments in the allotted time period. This document provides experiments that were designed for the middle year in a 3-year biology…

Twelve desk-top experiments and demonstrations which illustrate properties of and facts about gas are presented. Each experiment includes: purpose, materials needed, instructions, and a list of facts and properties that have been observed. Several of the activities also include questions for students and items for discussion. The topics of the…

To help undergraduate psychology students learn basic concepts in the experimental method, a basketball game is construed as a psychology experiment. Although no formal evaluation of the effectiveness of the basketball analogy as a learning device was conducted, students responded favorably. (RM)
