In their own words
ChemCollective Virtual Lab
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.
PraxiLabs
PraxiLabs provides virtual science labs and educational content for learners and education providers. Its simulations cover biology, chemistry, and physics, with more than 220 available in the Semester and Annual plans. Learners interact with experiments in 3D, can repeat them, track progress, and receive immediate feedback. Oxi, described as a virtual science lab partner, provides personalized guidance during simulations. The platform also includes multiple-choice quizzes and assessments, reports, and analytics. Individual subscriptions are limited to one user: the Free Plan gives one month of access to three simulations, while the Monthly Plan provides any 10 simulations. Semester and Annual plans include access to all 220-plus simulations. The School plan lists Moodle, Blackboard, and other LMS integrations, plus a built-in mini-LMS; Teacher and University plans are also offered by quote. PraxiLabs runs online in a modern browser on a computer or laptop, with no installation required. The Free Plan costs nothing, the Monthly Plan $6.99 a month, the Semester Plan $29.99 a month, and the Annual Plan $44.99 a year.
