ChemCollective Virtual Lab vs LabXchange

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.

LabXchange is a free digital science education platform created at Harvard University with support from the Amgen Foundation. Learners and educators can assemble videos, assessments, and simulations into personalized learning journeys. Its resource library includes simulations, interactive materials, worksheets, lesson plans, and educator resources. Virtual labs provide environments for working through experiments, and some simulations add a notebook containing background information. Educators can create private classes, share content, and track learner progress. Public material can be distributed through Google Classroom, Facebook, Twitter, Pinterest, or a direct link. LabXchange says it is ad-free, does not sell student data or use it commercially, stores student data on U.S. servers, and follows the NIST Cybersecurity Framework for security practices. Users may register directly or through Google or Facebook sign-on. The service supports Windows, macOS, ChromeOS, major browsers, and mobile browsers, and is intended for organizations and people aged 13 or older.
