Labster vs PhET Interactive Simulations

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.

PhET Interactive Simulations provides interactive science and mathematics simulations for students from preschool through university. Its design emphasizes scientific inquiry, visual mental models, multiple representations, real-world connections, and flexible classroom use; the simulations include virtual experiments and guided lessons. PhET says simulations are evaluated for educational effectiveness through student interviews and classroom observation. All are open source, and they are written in HTML5, with some legacy simulations in Java or Flash. They can run online or be downloaded. Android and iOS apps include HTML5 simulations and translations for offline use and automatically download new HTML5 simulations. A desktop app provides HTML5 and Java simulations and translations for offline use on Windows and macOS. The service is available on the web, Windows, macOS, iOS, Android, and select Chromebooks. Android browser-based HTML5 simulations and Linux are not officially supported. The free simulations plan is available to students and teachers. Commercial use requires a license from the University of Colorado Boulder.
