* Inclusion of realistic 3D simulations that behave very much like the real thing. This isn’t just setting a value and reading something off the screen. These incorporate the physicality of the experiments, which might mean positioning yourself so that a moving needle can be seen accurately by using your position to remove parallax. * Based on academic research into teaching online. * Coverage of all of the required practicals (AQA). * Inclusion of background information on each experiment. * Detailed accounts of how to perform the experiment for real or with the simulation. * The simulations have the Association for Science’s Green Tick of approval.
