Molecular Workbench vs WhimsyLabs

Molecular Workbench is a free modeling tool for designing and conducting computational experiments across science. Its interactive learning environment supports science inquiry, while its authoring system lets instructional designers create and publish curriculum based on models and simulations. Users can customize simulations or create their own, with topics spanning gas laws, fluid mechanics, states of matter, chemical reactions, genetics, protein synthesis, and quantum phenomena. Activities can include assessments, student-data collection, learning monitoring, and teacher feedback. Simulations can also be embedded in blogs, wikis, or web pages. The Next-Generation Molecular Workbench brings computational experiments to browsers using HTML5. An offline version is available, but it cannot access the latest simulations or collect student data. Downloads are listed for Windows, Mac OS X, and Linux, and require Java Runtime Environment 1.5 or later. The maker says the software needs considerable computing power and may start slowly while the Java virtual machine launches. Molecular Workbench is developed and maintained by the Concord Consortium.

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.
