The authors describes their experiences incorporating the virtual lab into a simple circuit lesson during an energy unit in a sixth-grade class. The lesson included a hands-on group experiment using wire, batteries, and light bulbs to make a circuit and an online simulation, using a virtual lab. Class discussions, student inquiries, and the study of scientific terminology are also discussed. The authors caution that, although the use of virtual tools does have a place in exploration and concept development, these simulation tools may not be as useful as a first-hand, multisensory experience. Instead, the virtual tool could be used to augment and reinforce student ideas after they have been authentically developed by the students through use of real materials.
