Discusses the equipment and techniques for taking photographs using a sound-actuated trigger. Describes a method using two flash units, two sound triggers, and a high-frequency clock to measure speeds. Provides several high-speed photographs. Lists 11 references. (YP)

Discusses a high school advanced placement physics course cooperating with neighboring college. Describes the background, titles of experiments, report format, and discussion. (YP)

Discusses the flotation method for the determination of the density of solids. Provides the stepwise experimental procedure with typical data tables and graphs. (YP)

Describes a course entitled "Biotechnology Laboratory" which introduces a variety of laboratory methods associated with biotechnology. Describes the history, content, and seven experiments of the course. The seven experiments are selected from microbiology and molecular biology, kinetics and fermentation, and downstream…

Describes unexpected experiences with student laboratory activities. Makes recommendations for addressing two types of lab disasters: (1) when lab preparations fail prior to the beginning of lab; and (2) when students produce unexpected results with the proper use of materials. (Contains 11 references.) (WRM)

Despite efforts to engage students in the traditional lecture environment, faculty in Georgia Southern University's Physics Department became dissatisfied with lecture as the primary means of instruction. During the fall semester of 2006, our department began adapting the studio model to suit the needs of introductory calculus-based physics…

The purpose of the U.S. Department of Education's online newsletter "The Education Innovator" is to promote innovative practices in education; to offer features on promising programs and practices; to provide information on innovative research, schools, policies, and trends; and to keep readers informed of key Department priorities and…

During the past three years we have been designing and implementing a technology enhanced urban ecology program using geographic information systems (GIS) coupled with technology. Our initial work focused on professional development for in-service teachers and implementation in K-12 classrooms. However, upon reflection and analysis of the…

Clickers were used for real-time data collection in two introductory biology laboratory courses so that students could perform statistical analysis on large data sets. Student attitudes toward this use of clickers were surveyed and students were administered a pre- and posttest on statistical content. Capture of large data sets allowed instructors…

This study compares characteristics of fluency in student audio journals recorded in a laboratory setting with those recorded using mobile audio devices. Forty graduate students enrolled in four oral communication courses at an American university recorded weekly audio journals for a 10-week term. Students chose the environment in which they…

This publication presents changes and modifications for 2007-2008 to the "International Rules for Precollege Science Research: Guidelines for Science and Engineering Fairs." It is written to guide fair directors, teachers, scientists, parents, and adult volunteers as they pursue their work of encouraging students to explore and investigate their…

In our Fundamentals of Genetics lab, students perform a wide variety of labs to reinforce and extend the topics covered in lecture. I developed an active-learning lab to augment the lecture topic of mutagenesis. In this lab exercise, students determine if a compound they bring from home is a mutagen. Students are required to read extensive…

A three-dimensional pendulum, modelled after the Laser Interferometer Gravitational-Wave Observatory's suspended optics, was constructed to investigate the pendulum's dynamics due to suspension point motion. In particular, we were interested in studying the pendular-pitch energy coupling. Determination of the pendular's Q value (the quality factor…

One aim of physics laboratory instruction is to help students connect theory to practice. So experiments are often chosen in order to "demonstrate" specific concepts. Furthermore, students are expected to approach phenomena in a scientific way, that is, they should develop a hypothesis and plan their experiments accordingly. Although it is usually…

Physics labwork has for a long time now been an important part of academic physics education. But demands on physics education have changed. However, while seminars and lectures have easily been updated with the latest content, it is much more difficult to modernize labwork courses: mere changes of content require expensive new equipment, tight…
