Virtual lab simulations allow students to complete laboratory experiments through the web online and explore abstract concepts & complex theories without stepping into a physical science lab. These simulations visualize science at a molecular level, offering open access to students. One can apply their scientific knowledge to advanced lab equipment to solve real-world challenges, such as DNA and gene sequencing, virtual reality surgical training, nursing, medical simulation, biology simulations, chemical reactions and mathematical concepts. Most importantly, eLearning tools allow the student to conduct various experiments without any constraints on place or time, in contrast to the challenges of real labs.
