Concord Consortium Lab vs WhimsyLabs

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.

WhimsyLabs is virtual laboratory software where students conduct simulated experiments in Biology, Chemistry, Physics, and Electronics. Its simulation engine models fluids, heat, and molecular behavior, including impurities and differences between samples. WhimsyCat guides students in response to their lab actions without a student chat window, while assessment evaluates experimental processes and techniques and asks follow-up questions tied to experimental data. Teachers can paste a written lab protocol into the AI Experiment Builder to create a custom lab scenario without programming. The platform includes a teacher dashboard and names Google Classroom, Canvas, Schoology, and LTI among its integrations. It runs in a browser on desktops, laptops, and Chromebooks, with optional VR headsets; Android, iOS, Linux, macOS, and Windows are also listed. Accessibility options include control remapping, text-to-speech, self-paced modes, and low-bandwidth operation. Labs can be cached or downloaded for offline use. Institutional pricing is by request, and a free trial is available, with no duration specified.
