Virtual chemistry labs for high school
Choose a chemistry question, change a condition, and explain the evidence from an interactive 3D investigation.

Measure an unknown
Use a titration curve to infer concentration, or compare chromatograms under matching conditions. Retain the measured volumes or distances before calculating a result.
Predict how a chemical system responds
Disturb an equilibrium and compare its new mixture with the starting state. In a cell investigation, connect a voltage observation with the reacting species rather than guessing from metal names.
Explain structure through observations
Compare flame observations or molecular shapes with their underlying representations. Name the evidence that distinguishes your explanation from another possibility.
Choose a course for your setting
These are individual investigations for grades 9–12. A first titration comparison benefits from familiarity with concentration and mole ratios; the public course guide explains the setup before you run it. Use a computer with a current browser and WebGL2 support for the 3D view.
All 23 chemistry investigations
Choose by the question you want to answer. Each public guide describes its setup, measurements, and current access condition.
Chemistry
Acid–Base Titration
One drop, six pH units. Find the equivalence point and pKa.
Chemistry
Gas Laws
Squeeze, warm, and cool trapped air. Find absolute zero.
Chemistry
Reaction Rates
Magnesium in acid: change one condition, time the gas.
Chemistry
Periodic Trends & Reactivity
Drop lithium, sodium, and potassium into water, then pull electrons off their atoms. What explains what you see?
Chemistry
Flame Tests & Atomic Spectra
Dip a salt in a flame and the color changes. What is the light really made of?
Chemistry
Molecular Shapes (VSEPR)
Build molecules from balls and sticks. Why is water bent but CO₂ straight?
Chemistry
Bonding & Properties of Solids
Test unknown solids for melting, dissolving, and conducting. Identify the bond type.
Chemistry
Evaporation & Intermolecular Forces
Wrap probes in alcohol-soaked paper. Which liquid cools fastest, and why?
Chemistry
Polymers & Designed Materials
Stretch, bend, and cross-link polymers. How does chain structure change the material?
Chemistry
Heating Curves & Phase Changes
Heat ice until it boils. Watch the thermometer and the energy meter.
Chemistry
Solutions & Solubility Curves
Add salt and sugar spoon by spoon, then heat and cool a solution. When does it become saturated?
Chemistry
Chromatography & Separation
Separate the dyes in a marker. Which molecules travel farthest, and why?
Chemistry
Spectrophotometry & Beer's Law
How much dye is in the drink? Build a calibration curve and find out.
Chemistry
Moles, Formulas & Limiting Reactants
Burn magnesium to find its oxide formula, then seal a reaction in a bag. Does the mass change?
Chemistry
Reaction Types & Activity Series
Drop metals into salt solutions. Which ones react, and what do the atoms do?
Chemistry
Precipitation & Gravimetric Analysis
What makes some water "hard"? Test water samples and measure what is in them.
Chemistry
Hand Warmers: Enthalpy & Hess’s Law
Design a hand warmer that reaches 20 °C above room temperature. Which salt, how much?
Chemistry
Equilibrium & Le Châtelier
Add, remove, heat, and cool. Watch the color shift as the equilibrium pushes back.
Chemistry
Acids, Bases & pH
Two acids, same concentration. Test them with probes, indicators, and a light bulb.
Chemistry
Buffers
Two liquids read the same pH. Add the same acid to both and predict what happens. Then design your own buffer.
Chemistry
Rate Laws: Crystal Violet
Track a fading dye with light. Is the reaction first or second order?
Chemistry
Electrochemical Cells
Build a battery from two metals and a salt bridge. Then run it backwards to plate copper.
Chemistry
Redox Titration: Hydrogen Peroxide
Titrate peroxide with purple permanganate. The first lasting pink tells you how much was there.
Try an investigation before choosing a plan
The Newton’s second law demo runs without an account. Sign in to start one shared seven-day trial when you first open any flagship lab. Other simulations require paid access; course guides remain public.

Questions before you begin
Is this a complete high school chemistry course?
These are individual simulated investigations, not a complete chemistry curriculum. Pair selected activities with your teaching sequence and required hands-on laboratory work.
Where can I check the variables and model conditions?
Open a course guide for its apparatus, adjustable conditions, reference examples, and FAQs. Course titles and membership here come from the current course catalog.
