Free Interactive Science & Math Simulations
Explore a growing library of animated, simulations for Math, Physics, Biology, Chemistry & Computer Science. Free to start, curriculum-aligned, with new simulations added every week. Drag a slider, press Play, and watch concepts click.
Free previews in every category. No credit card to browse. New simulations added weekly.
Learning That Moves
No passive videos. Every simulation responds to you in real time.
Adjust & Explore
Drag sliders and change variables to instantly see how each concept reacts.
Play, Pause, Reset
Control the action at your own pace — replay tricky moments as often as you like.
Live Readouts
Watch real numbers update as you experiment, building real intuition.
Topic Notes
Each simulation comes with a colorful one-page note to make learning easy.
Built for the Classroom — and the Curious Student
Whether you're preparing a lesson or studying for an exam, interactive simulations make concepts stick.
🍎 For Teachers & Educators
Project a simulation on the board in seconds. Adjust variables live in front of the class and watch concepts click — no lab equipment, no setup time. Perfect for STEM, physics, chemistry, and biology lessons at every level.
Upgrade Your Classroom🎓 For Students
Stuck on projectile motion? Confused by wave interference? Don't just read about it — interact with it. Adjust variables yourself, observe cause-and-effect in real time, and build the deep intuition that scores marks in exams.
Study SmarterWhy Interactive Beats Video — Every Time
Research consistently shows that students who do learn more than students who watch. Our simulations are designed around that principle.
Hands-On Exploration
Every simulation has sliders, buttons, and real-time readouts. Students experiment with variables themselves — not just watch someone else do it.
Instant Cause & Effect
Adjust gravity and watch the projectile arc change instantly. See Ohm's Law update live. That immediate feedback is what builds lasting intuition.
Curriculum-Aligned
Simulations covering physics, chemistry, biology, mathematics, and more — mapped to real topics students and teachers encounter every day.
Zero Setup. Always Ready.
No software installs, no lab prep, no equipment. Open any simulation instantly in any browser — a 30-second demo that takes 30 minutes to set up in a real lab.

What Teachers & Students Say
“I projected the pendulum simulation mid-lesson and every student had their hand up with questions. That almost never happens. Incredible engagement.”
“I finally understood projectile motion after spending five minutes dragging the angle and velocity sliders myself. No textbook explained it as well as this.”
“The free previews were so good they sold me immediately. My whole class uses it weekly now — it's replaced my old lab demo setup entirely.”

Frequently Asked Questions
What subjects are covered?
Physics, chemistry, biology, mathematics, and more — with new simulations added regularly across all categories. Browse our latest additions to see what's new.
What do I get for free?
Selected simulations are completely free to interact with — look for the Free badge. Subscribe to unlock everything.
Do the simulations work on school computers and tablets?
Yes — all simulations run in any modern web browser (Chrome, Firefox, Safari, Edge) with no plugins or software installs required. Mobile and tablet friendly.
Can teachers use this for whole-class projection?
Absolutely. Every simulation is designed to look great on a projector or interactive whiteboard. The full-screen iframe scales and fits automatically.
Is there a long-term contract?
No. Monthly and yearly plans can be cancelled at any time — no penalties, no lock-in.
