Science Lab Simulation for Students
Explore science through hands-on browser simulations. Designed for students, teachers and adult learners, with Indonesian and English guidance.
Choose among twelve original labs, from instrument-reading activities to interactive 3D chemistry workbenches. Each lab brings its own guided workflow, coded practice, notebook, CSV export and printable worksheets with matching keys. Search by a lab’s name, subject or topic, or browse the full list below.
These are educational browser applications. Read each lab’s model and reference notes for its scope and limitations; a simulation does not certify equipment, samples or a real laboratory procedure. Interactive controls require JavaScript. Search text and subject choices stay in this browser and are not added to URLs or analytics.

Our inspiration
This independent AZ ModestSoft collection was inspired by Lab Maya ↗, available through Indonesia’s Ministry of Primary and Secondary Education (Kemendikdasmen). Our simulations use original code, artwork and learning activities.
