OverviewĬhemLab is a Shareware software in the category Education developed by Model Science Software. These user designed simulations combine both text based instructions and the simulation into a single distributable file. Users can expand upon the original lab set using ChemLab's LabWizard development tools, thus allowing for curriculum specific lab simulation development by educators. Users step-through the actual lab procedure while interacting with animated equipment in a way that is similar to the real lab experience.ĬhemLab comes with a range of pre-designed lab experiments for general chemistry at the high school and college level. Commonly used lab equipment and procedures are used to simulate the steps involved in performing an experiment. Model ChemLab is a unique product incorporating both an interactive simulation and a lab notebook workspace with separate areas for theory, procedures and student observations. It has continued to be developed with extensive input from educators interested in the possible application of computer simulations for classroom and distance learning. Model ChemLab originated from academic work in computer simulation and software design at McMaster University. Whether your challenge is to introduce new computer technology to your curriculum, or bring the lab experience to on-line students or a need for an alternative to dangerous, expensive or environmentally hazardous labs, then Model ChemLab is the classroom proven solution for you.
