Presents a technique that allows high school biology students to view materials not normally seen in the laboratory environment using a computer and videodisk technology. (MDH)

From a survey of 1,000 high school students, the following science anxieties were found: (1) danger anxiety, (2) test anxiety, (3) math and problem-solving anxiety, (4) squeamish anxiety, (5) performance anxiety, and (6) classroom anxiety. (PR)

Describes an inexpensive and sturdy model of protein synthesis that students can make in groups or that can be used by the teacher for demonstrations. (PR)

Presents a series of activities and a discussion of William Harvey's research to help students understand blood circulation. (PR)

Discusses the educational implications of Geographic Information Systems, a technology that provides ready access to an array of geographical data. (PR)

Presents a simple activity designed to allow students to experimentally verify Kepler's second law, sometimes called the law of equal areas. It states that areas swept out by a planet as it orbits the Sun are equal for equal time intervals. (PR)

Presents a design for constructing a colorimeter as an alternative to the more expensive spectrophotometer. The materials cost less than $25.00. (PR)

Presents instructions for students examining compost heaps to learn about the compost organisms and their place in the detritus food web. (PR)

Presents and describes New York State's desired learning outcomes that integrates mathematics, science, and technology outcomes. (PR)

Describes approaches and benefits of having students make observations and inferences from tracking-pattern diagrams and actual tracks made in sandboxes. (PR)

Describes how spreadsheets can be used for helping students learn about direct current electrical circuits. (PR)

Explains the importance of discussing women scientists in science instruction. Describes the life and work of Rachel Carson (1907-64), Annie Cannon (1863-1941), Estelle Ramey (1913-), and Chien Shiung Wu (1912-). (PR)

Describes the P- and S-waves associated with earthquakes and presents a game that is a seismic simulation. The object of the game is to locate the origin of an earthquake, which will be a student in the class. The game can be used for all age levels. (PR)

Describes an activity to simulate the geometries of a spreading pathogen such as HIV throughout a generation. Students exchange "bodily fluids" three times and are then tested for the presence of "infection." Materials used include base solutions (NaOH or KOH), phenolphthalein (pH indicator), clear plastic cups, and an eye dropper. (PR)

Describes an easy and inexpensive method of preparing experimental growth media that high school students can use for plant cloning investigations. (PR)
