Interactive Science Simulations
These tools were created from teaching needs: students can manipulate relationships rather than simply read about them. The library now presents that depth with stronger visual routes into physics, chemistry and biology.
Physics visual lab
Space and fields
AQA field, astronomy and particle-motion tools that connect observation, stellar life cycles and quantitative field models.
Chemistry visual lab
Spectra and particles
Use spectra as evidence: atomic line spectra for energy levels and NMR for molecular structure.
Biology visual lab
Living systems
Move from ecosystem resilience to cell division, chromosome behaviour and sources of biological variation.
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 occur.
- 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
Biodiversity Shock Simulator
Target Level: Key Stage 3 / GCSE
Contrast low and high biodiversity ecosystems under environmental stress. Introduce grass diseases, pesticides, or habitat changes and observe the step-by-step cascade of species extinction.
- Toggle "Predict First" mode to test students before changes
- Observe interactive flow lines representing energy transfer
- Access embedded teacher notes and discussion scripts
Electric & Magnetic Fields Lab
Target Level: GCSE / A-Level Physics
Build electric and magnetic field patterns, test forces on charges and current-carrying wires, then extend to charged-particle motion and crossed fields.
- Visualise fields, vectors, probes and equations
- Practise E = V/d, F = BIl, F = Bqv and v = E/B
- GCSE concept mode plus A-level quantitative extension
Emission & Absorption Spectroscopy
Target Level: GCSE / A-Level Chemistry & Physics
Connect quantised electron transitions with bright emission lines, dark absorption lines and element identification.
- Compare emission, absorption and aligned spectra
- Calculate photon energy with E = hc/λ
- Identify unknown elements from line positions
Cell Division Studio
Target Level: GCSE / A-Level Biology
Compare mitosis and meiosis through an explorable chromosome model with stage-by-stage prompts, counters and misconceptions.
- Step through mitosis, meiosis I and meiosis II
- Track ploidy, cell count and genetic similarity
- Show crossing over and independent assortment
