In their own words
Concord Consortium Lab
Concord Consortium Lab is an open-source HTML5 framework for scientific models, visualizations, graphing, and probeware. Authors define Lab Interactives in JSON, combining models with inquiry controls such as buttons, checkboxes, sliders, and graphs. Interactives can be created, shared, and embedded. Listed model types include Next Generation Molecular Workbench, Energy2D, and Probeware, with bar and line graphs available for activities. Lab combines simulations from multiple modeling engines with data collection from sensors and probes; one demonstrated model explores charged and neutral atoms through two-dimensional molecular dynamics. The framework runs on Android, iOS, and the web, requires SVG support, and lists iOS Safari and Chrome for Android among supported browsers. Concord says current desktop browsers provide the best performance, while simpler models may run on tablets and phones. The project uses Simplified BSD, MIT, or Apache 2.0 licensing. Download archives are available, and local content must be served through a web server. Concord says student and teacher data is confidential and not used for targeted advertising.
