Virtual labs are interactive, digital simulations of activities that typically take place in physical laboratory settings. Virtual labs simulate the tools, equipment, tests, and procedures used in chemistry, biochemistry, physics, biology, and other disciplines that include a laboratory component in the curriculum. A key characteristic of virtual labs is their interactivity—video recordings or renderings of lab activities that cannot be manipulated by users fall outside this discussion. Similarly, physical equipment such as radio telescopes orelectron microscopes that can be controlled by distant users is considered remote instrumentation rather than a virtual lab.
