WhimsyLabs: The Practical Virtual Lab for STEM Education
Stop clicking 'Next.' Start doing science.
WhimsyLabs isn't just a simulator; it's a playground of particles. We combine a best-in-class Physicality-First engine with AI-driven assessment to deliver the only virtual lab that builds true muscle memory while saving teachers hours of marking time.
One platform, two ways to learn: real science, anywhere.

Desktop (Chromebook/Mac/PC)What is WhimsyLabs?
WhimsyLabs is award-winning virtual laboratory software that lets students conduct realistic science experiments on any device. Unlike traditional simulations that follow rigid scripts, WhimsyLabs uses real physics engines to create authentic laboratory experiences where students build genuine muscle memory. Our AI-powered assessment grades practical skills automatically, saving teachers hours of marking time while preventing AI-assisted cheating. Used by schools for Chemistry, Biology, Physics and Electronics, WhimsyLabs works on VR headsets, Chromebooks, Macs, and PCs, no special equipment required.
Why Do Virtual Labs Need Real Physics Engines?
Unlike "slide-show" simulators, our engine replicates the chaos and weight of the real world, down to temperature perturbations, impurities and deviation between samples. Whether pouring titration fluids in VR or adjusting microscope focus on a Chromebook, students must use fine motor skills and procedural accuracy.[1]
If they drop a beaker, it breaks. If they overheat a compound, it reacts.
This "freedom to fail" builds resilience and genuine understanding of laboratory risks.
- Good pipetting technique
- Minor inconsistency in swirling
- Consistent results achieved
- All PPE worn correctly
- Bench spillage cleaned promptly
- Burette readings recorded
- Calculation method correct
- Minor rounding errors
- Lab report adequate but lacks detail
- Error analysis shows understanding
How Does AI Grade Science Practicals?
WhimsyLabs AI-proofs assessments by grading the process, not just the result. We track physical inputs within our virtual labs, like equipment handling and reaction times, which AI cannot simulate.
Every student's reagents have slightly different concentrations and impurities, so every student gets a unique correct answer. AI tools assume textbook-perfect conditions, but your HCl was 0.0987M with trace iron. A generic "correct" answer won't match your actual data.
💡 This makes WhimsyLabs perfect for homework: students can't share answers or use AI to cheat.
Your titration data: Initial burette reading: 0.50 mL | Final reading: 24.80 mL | NaOH concentration: 0.10 M
Using YOUR experimental values, calculate the concentration of the HCl solution in mol/L. Show your working.
Can Automated Grading Save Teachers Time?[2]
Stop ticking boxes and start teaching. WhimsyLabs assesses skill mastery and safety in real-time, providing automatic grading on students' capabilities for you to review.
How Can Teachers Customize Virtual Experiments?
Planning a course means matching labs to curriculum expectations. We've built labs specifically for what you need to teach; stoichiometry, titrations, electrolysis, and more.
Use them as-is, or customize the pre-lab and discussion questions to fit your lesson plan. Most teachers modify existing labs slightly, and we make that easy.
Need something completely custom? Our AI Experiment Builder lets you paste any protocol and generate a full lab scenario in minutes.
Access the Worldwide Lab Library: Labs created by educators are shared across the entire WhimsyLabs community. Browse practicals from teachers around the globe, adapt them for your students, and contribute your own creations back to the community.
Acid-Base Titration Practical
Objective: Determine the concentration of an unknown HCl solution using standardized NaOH.
What Student Analytics Do Virtual Labs Provide?
Our dashboard offers a real-time view of student performance, not just grades. Instantly identify struggling students for timely intervention before they fall behind.
Export reports easily or integrate directly with your LMS to track progress from individual students to entire regions.

Why Students Love WhimsyLabs[3]
Can Students Design Their Own Experiments?
Students aren't limited to following instructions. They can mix any reagent with any equipment to test their own hypotheses and see real consequences. Curiosity-driven learning, safely contained in a virtual environment.
How Does Virtual Lab Software Support SEND Learners?
Inclusive by default. We support full control remapping, text-to-speech, and self-paced modes for SEND learners. Plus, our low-bandwidth mode ensures smooth operation even on unstable school internet connections.
How Does Gamification Improve Science Learning?
We use gamification to drive understanding, not screen time. Students earn free Lab Points for safety and accuracy to customize their virtual workspace. This builds intrinsic motivation to improve skills without using predatory engagement tactics.
