A Simulation is a highly interactive Java-, Flash- or HTML5-based program that realistically models real-life objects and processes related to home appliances and systems, sports, 'green' energy sources and related processes, telecommunications, biotechnology, medicine, etc.

Colorful state-of-the-art graphics, realistic animations, game-like interface and functionality allows teachers to present learning topics in a format that teenagers and young adults have traditionally found interesting and engaging.
Simulations enable learners to: (1) observe the physical processes insightfully at different levels of detail, (2) analyze constraints between relevant parameters, (3) push these parameters beyond normal allowed values and to simulate dangerous or emergency situations that might be experienced, (4) make and check "what if" predictions, and (5) acquire virtual data for further handling and detailed analysis.

Simulations are task and learner neutral, and within their functionality, there are no restrictions on the user's actions. Simulations are indispensable tools for lesson demonstration.
