Remote access technologies enable students to investigate science by utilizing scientific tools and communicating in real-time with scientists and researchers with only a computer and an Internet connection. Very little is known about student perceptions of how real remote investigations are and how immersed the students are in the experience.…

There is a wide range of new products emerging from nanotechnology, and "nano ice cream" is an easy one that you can use to teach topics from surface area to volume applications. In this activity, students learn how ice cream can be made smoother and creamier tasting through nanoscience. By using liquid nitrogen to cool the cream mixture, students…

As a "new science," nanotechnology has brought many nanoscale-based applications to the forefront of society. This article describes one such application--a nanosensor that can precisely detect a variety of chemical stimuli in the environment--and presents the science behind it as an interdisciplinary science topic. This article also provides…

Describes bioluminescence and the chemistry of how it occurs. Presents information for conducting the following classroom activities: (1) firefly mimic; (2) modeling deep-sea fish; (3) sea fireflies; and (4) the chemistry of light. (PR)

Presented are seven investigations that examine circadian rhythms. Topics include attention span, body temperature, rhythms found in rodents and spiders, and possible genetic determination of circadian rhythms. Background information on plants and animals is given. (KR)

Classroom interactions were examined for gender differences that may contribute to the underrepresentation of women in physics and engineering courses and subsequent careers. (PR)

Reviews the literature concerning sociocultural factors, teacher influences and experiences that effect girls attitudes about entering science careers. Discusses a model of these influences on girls. Makes recommendations including increased opportunities and encouragement to foster more favorable attitudes toward science and increase science…

Investigated were the seating patterns of target students in science classrooms to see whether there was an action zone or T zone present. Questioning level, understanding level of students, and pacing of instruction by teachers are discussed in terms of target students. (KR)

This study investigated the seating patterns of target students in science classrooms to see if there was an action zone or t-zone present. Fifty-six physical science and chemistry classes were observed using the Brophy-Good Teacher-Child Dyadic Observation System. Target students were identified and their interactions were compared to non-target…

Nationally many middle-level schools are changing from a traditional junior high school structure (grades 7-9) to middle schools (grades 6-8). A case study examined the impact of middle school organizational changes that occurred as a large North Carolina school system converted from junior high schools to middle schools on science teachers and…

This study investigated the impact of haptic augmentation of a science inquiry program on students' learning about viruses and nanoscale science. The study assessed how the addition of different types of haptic feedback (active touch and kinesthetic feedback) combined with computer visualizations influenced middle and high school students'…

The underrepresentation of women in science and engineering might be caused by certain differences in science training processes. This study investigated sex differences in classroom atmosphere and classroom behaviors of science teachers and students. Males were dominant in working on classroom displays and classroom activities. (YP)
