Charging a capacitor with a photovoltaic module is an experiment which reveals a lot about the modules characteristics. It is customary to represent these characteristics with an equivalent circuit whose elements represent its physical parameters. The behavior of a photovoltaic module is very similar to that of a single cell but the electric…

This article describes a five-day online energy module, developed by the Concord Consortium (an educational research and development organization) in which students compare the effects of various energy sources on air quality, water quality, and land use. The module's interactive models explore hydraulic fracturing, real-world data on energy…

Aaron Sebens and his fourth grade students received this congratulatory tweet from the White House as a response to the solar-powered classroom that they created in 10 weeks. The process--defining the goals, raising funds, construction, and implementation--involved many subject areas: reading, writing, math, science, and social studies. This…

Physical design projects are a way to motivate and engage students in authentic science and engineering practices. Web-based tools can support design projects to ensure that students address and reflect upon critical science concepts during the course of the project. In addition, by specifying challenging design goals that require students to…

Jamestown is at the heart of any teaching and learning of colonial American history. Stories of John Smith and Pocahontas are learned by elementary and secondary students across the United States. In Virginia, Jamestown is first taught in third grade and revisited five more times from historical, political, economic, and geographic perspectives.…
