Some ideas in science just don't click until you can move the variables yourself. You can read about projectile motion a dozen times — or you can drag the launch angle, watch the arc change, and suddenly it makes sense.

That's the idea behind SciFunLab: interactive science simulations that run in your browser. No installs, no signup, free. Pick a simulation, change things, and watch what happens.

What you'll find here

We cover physics, chemistry, and biology — from pendulums, circuits, and wave interference to concepts that usually only get hand-wavy diagrams, like quantum tunneling or statistical mechanics. There are also simulations aimed at competitive exam preparation (JEE, NEET, and more), where an interactive model can turn a memorized formula into something you actually understand.

If you're a student, use the simulations to test your intuition before an exam. If you're a teacher, they work well as classroom demos — a browser tab and a projector is all you need. And if you're just curious, poke around; breaking things in a simulation is free.

What this blog is for

Alongside the simulations, we'll publish articles that go deeper:

• Plain-language explanations of the concepts behind our simulations
• Guides on using specific simulations for studying or teaching
• Ideas for classroom activities and self-study experiments

Tell us what to improve

SciFunLab is actively being built, and honest feedback shapes what we work on next. If a simulation confuses you, if something's broken, or if there's a concept you wish you could play with — tell us. Requests genuinely drive the roadmap.
