Interactive Chemistry vs MoluCAD

Interactive Chemistry provides free science games and simulations for teaching topics from middle school through university level. Its activities cover ionic and covalent bonding, cellular respiration, reactions, and molecular interactions. Chemistry teacher Steven Sogo created the games with support from high school students at Laguna Beach High School. The Cell Model 2025 game is playable on iPads, Android tablets, and most phones. The Double Replacement Reaction Simulator works on laptops, Chromebooks, and mobile devices. In the Matchmaker double replacement game, students get immediate feedback when they form correct products and can practice balancing equations; its page also links to suggested lessons and an instructional video. The site lists Android, iOS, macOS, web, and Windows. Users can report bugs or suggest features through linked forms, and an email contact is provided. The maker describes its experiments and prototypes as unfinished and potentially buggy. Prototype code is available on GitHub for users to finish themselves. The listed plan is Free at free.

MoluCAD is a free Windows desktop application for molecular modeling and visualization, designed for chemistry students and originally conceived for organic chemistry study. Users can construct molecular structures in true 3D and inspect them from any viewpoint. The software creates reaction animations and includes more than 170 sample structures and animations that can be opened, viewed, and modified. Built-in MM2 energy minimization supports the modeling workflow, alongside an interactive periodic table and HTML-based help. MoluCAD imports and exports PDB, ENT, MOL, and MM3 files, and generates BMP, JPEG, and AVI files. New River Kinematics offers it as a free download through a Windows executable. The product originated in a three-year National Institutes of Health biomedical technology research project intended to produce low-cost chemistry education software. New River Kinematics, founded in 1994 and based in Williamsburg, Virginia, describes itself as an engineering company developing and supporting portable metrology software solutions.
