Labster vs Molecular Workbench

Labster provides interactive virtual lab assignments for teaching science concepts and practicing laboratory techniques. Its catalog includes more than 300 simulations across STEM subjects. Learners follow guided scenarios, repeat work at their own pace, and receive immediate feedback. Instructors can use automatic grading, customizable quizzes, and a modular assignment builder. A course mapping tool helps match simulations to a syllabus, and listed LMS integrations include Canvas, Google Classroom, Blackboard, Moodle, Schoology, and D2L Brightspace.

Simulations run in supported browsers on Windows and Mac computers. Some are available on iPads and Chromebooks through the Labster app; smartphones, including iPhones and Android phones, are not supported for playing them. Purchases are available to instructors, faculty, and administrators at educational institutions. A free trial is offered, but there is no free plan. Pricing is on request; institutional or department engagements typically begin at $5,000 a year, billed annually, with final pricing dependent on the solution and implementation requirements.

Molecular Workbench is a free modeling tool for designing and conducting computational experiments across science. Its interactive learning environment supports science inquiry, while its authoring system lets instructional designers create and publish curriculum based on models and simulations. Users can customize simulations or create their own, with topics spanning gas laws, fluid mechanics, states of matter, chemical reactions, genetics, protein synthesis, and quantum phenomena. Activities can include assessments, student-data collection, learning monitoring, and teacher feedback. Simulations can also be embedded in blogs, wikis, or web pages. The Next-Generation Molecular Workbench brings computational experiments to browsers using HTML5. An offline version is available, but it cannot access the latest simulations or collect student data. Downloads are listed for Windows, Mac OS X, and Linux, and require Java Runtime Environment 1.5 or later. The maker says the software needs considerable computing power and may start slowly while the Java virtual machine launches. Molecular Workbench is developed and maintained by the Concord Consortium.
