Interactive Science Simulations
These simulations are tools I use in my own science lessons to help clarify complex GCSE, A-Level, and undergraduate concepts. More simulations will be uploaded over time as they are developed.
Stellar Evolution 3D Interactive Simulation
Target Level: GCSE / A-Level / Undergraduate
Direct a star through its complete lifecycle in a fully rendered 3D environment. Adjust the initial solar mass and observe how it dictates the sequence of evolutionary stages.
- Control time progression to observe structural changes
- Adjust initial mass from 0.05 to 150 Solar Masses
- Track live data: temperature, radius, and luminosity
Internal Energy and States
Target Level: GCSE / A-Level
Investigate how thermal energy input affects the temperature and physical state of various substances. Monitor phase transitions across customisable thermodynamic parameters.
- Modify specific heat and latent heat capacities
- Observe visual particle-level state transitions
- Analyse live-updating heating curve graphs
Thermal Conduction Comparison Lab
Target Level: GCSE / A-Level
Compare the rate of heat transfer between different materials at the particle level. Observe the propagation of kinetic energy until thermal equilibrium is reached.
- Select and compare combinations of conductors and insulators
- Visualise energy transfer via particle collisions
- Monitor live temperature gradients across the materials
Nuclear Magnetic Resonance (NMR) Spectrum Simulator
Target Level: GCSE / A-Level / Undergraduate
Explore how Nuclear Magnetic Resonance (NMR) spectroscopy reveals molecular structure. Build or modify molecules and instantly generate predicted ¹H and ¹³C NMR spectra, including chemical shifts, splitting patterns, and integration. Use it to practise interpreting spectra, compare functional group effects, and test 'what happens if...' structural changes.
- Build/edit structures and functional groups
- Predict ¹H and ¹³C NMR shifts, splitting, and integration
- Great for exam practice and structure-solving
Thomson Crossed Fields
Target Level: A-Level (Turning Points)
A highly accurate 3D simulation of J.J. Thomson's canonical experiment to determine the specific charge of the electron (e/m) using balanced fields.
- Adjust electric plate potential and Helmholtz coils
- Observe macroscopic deflection of the electron beam
- Graph orbital radius vs magnetic field density
Collision Theory Simulator
Target Level: GCSE / A-Level (Kinetics)
Explore how temperature, concentration, pressure, surface area, and catalysts affect the rate of reaction. Monitor Maxwell-Boltzmann distributions and Arrhenius plots in A-Level mode.
- Visualise successful vs unsuccessful particle collisions
- Toggle Activation Energy constraints dynamically
- View live products-over-time and rate graphs
Dynamic Equilibrium
Target Level: GCSE / A-Level (Kinetics & Equilibria)
Explore reversible reactions and Le Chatelier's Principle through the industrial Haber Process. Understand why shifting conditions change the equilibrium position.
- Live forward & reverse reaction rate monitoring
- Real-time concentration vs time graphing
- Manipulate Temperature, Pressure, and Concentration
