This document discusses the benefits and challenges of traditional chemistry laboratories and how virtual laboratories can help address some of the issues. It notes that while traditional labs are effective for hands-on learning, they have high costs and safety/infrastructure challenges. Virtual labs provide a safer and less expensive alternative by simulating experiments on a web-based platform. They allow students to review materials before and after labs, see dangerous reactions safely, and optimize teaching and learning time. The document concludes that virtual labs are effective supplements that help students make better use of classroom resources like lectures and textbooks.
