ChemCollective Virtual Lab vs Science Remote Laboratory

ChemCollective Virtual Lab is an online chemistry simulation that connects calculations with laboratory-style experiments. Students and educators can use its web activities without licensing requirements, including experiments with hundreds of standard aqueous reagents across acid-base chemistry, thermochemistry, solubility, and redox topics. Teaching resources include prepared lab problems, tutorials, courses, real-world scenarios, visualizations, simulations, and concept tests. Autograded activities randomize unknowns and check answers, with hints and feedback. Teachers can make free classroom pages that collect activity links, instructions, and handouts, and track attempts on autograded problems. Instructors may modify activities or request custom ones. Downloadable versions for Windows and Mac are available, though Java may be needed. The project aims to help high school and college students approach chemistry like practicing scientists. Its current scope is aqueous reactions. The Virtual Lab is free for educators and students; the site and its contents are licensed under Creative Commons Attribution 3.0 NonCommercial-NoDerivs.

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.
