1. Modeling the physical phenomenon by a set of equations and carrying out simulations to yield the result of the particular experiment. This can, at - the - best, provide an approximate version of the ‘real - world’ experiment.
2. Providing measured data for virtual lab experiments corresponding to the data previously obtained by measurements on an actual system.
3. Remotely triggering an experiment in an actual lab and providing the student the result of the experiment through the computer interface. This would entail carrying out the actual lab experiment remotely.
