Explains the functions of the Boreal Forest Watch including the scope, level of student involvement, goals, and nature of the data collection. Details student involvement at the forest site. Contains 18 references. (DDR)

Describes a demonstration of the principles of a voltaic cell using lemon cells to power a calculator and other items. A lemon fortified with a penny and a galvanized nail produces a potential of one volt. (PVD)

Project ESTEEM (Earth Science Teachers Exploring Exemplary Materials) is designed to improve earth science teaching by providing materials and personnel to reverse the decline in activity-based instruction. During an intense summer program, precollege teachers examine and present activities for earth-science courses. These materials are assembled…

Discusses advantages of a video-based, digitized image system for the study and analysis of projectile motion in the physics laboratory. Describes the implementation of a web-based digitized video system. (WRM)

Using the seasons in the science classroom increases student observation skills as they focus on subtle differences such as shades of color and differences in structures. In this article, the author presents a variety of activities that can help students identify and demonstrate patterns and changes in leaf or plant development. The ability to…

Most people are frustrated with the current scientific method presented in textbooks. The scientific method--a simplistic model of the scientific inquiry process--fails in most cases to provide a successful guide to how science is done. This is not shocking, really. Many simple models used in science are quite useful within their limitations. When…

Historical perspectives on science serve to humanize the sciences, increase student motivation, communicate academic content, and convey the nature of science. This paper briefly reviews pertinent literature regarding the history of science and narrates the author's experiences of incorporating historical perspectives in high school biology…

While a voluminous lecture hall can present obstacles to effective teaching and learning, large classrooms containing more than 100 students also present teaching opportunities. The lecture hall offers an excellent arena for demonstrating concepts that lend themselves to demonstrations and something this author refers to as "group performances."…

This article uses a functional view of language to frame and analyze issues of language and content in mainstream classrooms. Describing a Western Canadian grade one/two science class, it examines how a teacher and her class of young ESL students were able to build up a simple theory of magnetism in a scientific register, link its technical terms…

Students from five high schools participated in a 2 to 4-week microcomputer based laboratory (MBL) physics curriculum in two groups. One group completed the curriculum entirely online, and the other completed the same curriculum in a traditional classroom setting. Variables were collected to predict student success on a post-unit measure of…

The purpose of this study is to refine Japanese elementary science activity structures by using a CSCL approach to transform the classroom into a knowledge-building community. We report design studies on two science lessons in two consecutive years and describe the progressive refinement of the activity structures. Through comparisons of student…

In this activity, teachers in one state create and share an "exchange box" of environmental and cultural items with students of another state. The Environmental Exchange Box activity enables teachers to improve students' skills in scientific inquiry and develop attitudes and values conducive to science learning such as wonder, curiosity,…

Last fall, "Science and Children" invited kindergarten to grade eight teachers to participate in a study investigating students' ideas about plants and plant growth (Barman et al. 2002). Two hundred twenty-seven individuals from 16 states in the United States, one U.S. Territory, and one Canadian Province responded to this invitation and…

Recent events, such as the anthrax scares and the SARS outbreak, have forced teachers to focus on issues such as disease control and bioterrorism in their own backyards. Students are aware of the current biological issues in the news and are curious about infectious diseases and the issues relating to biological warfare. In order to address the…

The rapid development of science and technology has become a global issue in modern society, since it will not only bring conveniences into people's lives but it may also cause extensive environmental damage to the planet earth. Therefore, it is important to propagate the notion of Science Technology and Society (STS) and the awareness of…
