ChemCollective Virtual Lab vs MoleculAR

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.

MoleculAR is a free augmented-reality app for chemistry learning on Android and iOS. Users scan QR codes to open three-dimensional models of molecules, molecular geometries, and orbitals, then rotate and zoom them for different views. The app focuses on VSEPR molecular geometry and visualizing complicated molecules. A downloadable QR library provides available structures at no cost. Its reference includes molecules, s, p, d, and f orbitals, plus animations for Newman projection, the SN2 reaction, and ring flip. The maker describes MoleculAR for students and educators in chemistry education and accepts feedback or requests for new molecules by email. The privacy policy says the app does not collect data, while third-party services may collect identifying information. Error logs may include an IP address, device name, operating-system version, and usage date and time. The service does not address individuals under age 13.
