Finally, finding the space in the school, installing the proper chemical and fire safety systems, and having the lab inspected and approved for use. Moreover, let us not forget the liability insurance costs. Enter the Virtual Chemistry Lab. Visually its a podium with a VR headset and glove. A student puts on the VR equipment, logs in with their student ID and begins their lab session. Immediately they are immersed in a virtual high school chem. lab. Looking around they see beakers, flasks, scales, Bunsen burners and many chemicals. Following the instructions of the virtual teacher, they perform their required chemistry experiments. They mix chemicals, apply heat, observe and log the results, and, occasionally cause an explosion. If the class period ends in the middle of an experiment, they can "save" the experiment in midstream, and continue the following day exactly where they left off, chemicals under heat and all.VR in Business: Stock Market Analysis The June 1992 issue of Forbes magazine discusses data visualization used in the stock market.
