Concord Consortium Lab vs Science Remote Laboratory

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.

Science Remote Laboratory is a free web platform for virtual science experiments in university education. Its live library contains 34 experiments spanning physics, chemistry, biology, IoT, and robotics. Physics activities include an MNA circuit solver and an RK4 engine for mechanics simulations. IoT work uses a pseudocode interpreter for simulated sensors, MQTT, input and output, PID loops, and safety limits. Browser-based 3D laboratories use BabylonJS and Havok physics. Sessions persist, progress is saved, and multiple students can work in one lab simultaneously. The laboratories run in a browser without installation. The platform is presented for universities, public health organizations, and research institutions. Phase 01 is live; scientific visualization is listed as in development, with later phases upcoming. The Free to explore plan costs nothing. The project is headquartered in Harare, Zimbabwe.
