Describes the use of an indicator made from the pigment in red cabbage. Cabbage is grated then soaked in water. When the water is a strong red, the cabbage is strained out. The cabbage-juice indicator is then used to test for acids and bases. Includes a list of good foods to test for acidity and alkalinity. (PVD)

Explores measuring the specific heat of a metal ball. The ball is heated to a known temperature then placed in cold water. Students measure the temperature gain of the water in this investigation of the principle of Conservation of Energy. As a second task, students make a precise determination of the density of the ball. (PVD)

Describes the use of a mystery substance, Oobleck, in a graduate-level course for secondary special-education teachers that considered ways to teach science. Principles of science instruction, teaching students with diverse disabilities, instructional congruence, student assessment, and modifications are addressed. (DB)

Describes the authors' research behind the Historic Cancellation of Fact method, a solution to the information explosion crisis. Each existing paper is evaluated in the light of new papers published the day before, and any "old" paper which has suffered obsolescence is immediately pulled and republished in its entirety in SCRUB (Science Culling…

Describes a set-up for sending the infrared signal from a common remote control device to an oscilloscope in order to "see" the infrared signal. (WRM)

Describes the construction and use of a magnetic needle that is stronger than those conventionally used for experiments with electromagnetism. (WRM)

Discusses environmental resource assessment research conducted by undergraduate students as part of a non-science majors' chemistry course at Santa Clara University. Describes project procedures and course grading, chemistry connections, learning goals and outcomes, and implementing change on campus. (WRM)

Presents ideas for teaching elementary school children about scientific inquiry methods. Recommends a Planning Board to scaffold students' thinking as they plan and conduct scientific investigations. (WRM)

Presents two quantitative Faraday's law experiments using a computer-assisted data-logging system. (Author/ASK)

Discusses the training and preparation for the transition to block scheduling. Provides a summary of some of the aspects of the four-by-four block schedule and describes strategies employed to modify instruction and curriculum. Includes two sample interdisciplinary activities. (DDR)

Reports on the development of a series of assignments for use in a basic microbiology course involving sophomore-, junior-, and senior-level students from five different biology majors. Assignments include writing, a class debate, and case history studies. (Author/MM)

Describes the setup of a system that allows vibrations in two dimensions to demonstrate polarization states of light and particle spin. (WRM)

Summarizes ideas for new demonstrations, experiments, and science-in-society topics for teaching chemistry. (WRM)

A team of teachers, scientists, and high school students at the University of Texas Health Science Center at Houston has developed activities to teach concepts in learning through an inquiry-based laboratory method. The Learning Education and Research Network (LEARN) activities were field tested at the Society for Neuroscience Conference, in the…

A biochemical molecular modeling project on heme proteins suitable for an introductory Biochemistry I class has been designed with a 2-fold objective: i) to reinforce the correlation between protein three-dimensional structure and function through a discovery oriented project, and ii) to introduce students to the fields of bioinorganic and…
