To enhance teaching and learning about Earth's climate and global climate change (GCC) in secondary science classrooms, the authors are engaged in a four-year, National Science Foundation (NSF)-funded project to develop, implement, and evaluate a new four-week curriculum module grounded in the use of a data-driven, computer-based climate modeling…

This summer, on August 21, 500 million people across North America will experience one of the most beautiful astronomical phenomena: an eclipse of the Sun. It will be a "must teach" moment, when all students will want to know the "what, when, and why" of the event. In addition, many high school science teachers are likely to be…

Biomodeling is the study of the structures and behaviors of interacting biological entities such as molecules, cells, or organisms. While physical and chemical processes give rise to various spatial and temporal structures, even the simplest biological phenomenon is infinitely more complex (Kling 2004). Over the past decade, much of biomodeling…

Cruise planning may seem like an ordinary task for oceanographers, but it actually involves logical and strategic thinking, collaboration, and multidisciplinary work. The "Challenger" expedition, led by Charles Wyville Thomson from 1872 to 1876, was the first to be fully dedicated to understanding oceans (Rice et al. 1999) and was…

This article describes a unit in which students investigate total solar eclipses, such as the one coming August 21, from several perspectives. It incorporates mathematical thinking and aligns with the "Next Generation Science Standard." This article refers to physical, virtual, and mathematical modeling. Various models and perspectives…

Suggests cooperative learning projects if only one microcomputer is available for a large class. An example of such a project using a program dealing with correlating sedimentary rock layers through cross-sectional analysis is described. Instructional strategies and academic objectives of the three-module program are included. (JN)

Science teachers face challenges that affect the quality of instruction. Tight budgets, limited resources, school schedules, and other obstacles limit students' opportunities to experience science that is visual and interactive. Incorporating web-based Java applets into science instruction offers a practical solution to these challenges. The…

Several types of physics activities that use real-world problems to motivate learners, use computers to assist in developing conceptual understandings, connect problem situations to mathematical models, and use the models to analyze other real-world problems are presented. The topics of racing sports, sailing, and damped harmonic oscillations are…

Described is the generation of a scale model of the solar system and the milky way galaxy using a computer spreadsheet program. A sample spreadsheet including cell formulas is provided. Suggestions for using this activity as a teaching technique are included. (CW)
