For instance, having the students run through this series of virtual experiments before they run loose in a lab will make their lab time even more productive. Also, some experiments that require technical skill or experience are more easily accomplished using the virtual lab. I believe, in the ideal world, this virtual lab would complement and augment the real lab - not replace the real lab. Ideal Gas for Chemistry installed easily, if somewhat slowly. These experiments include detailed instructions on the theory, as well as instructions for performing the experiment.
Students can print out the instructions for later reference.
Ideal Gas for Chemistry includes a short introductory video that explains the series of experiments and a brief introduction to the software. As a typical mad scientist, I quickly assembled the various components and began my experiments. The Gas Laws are fairly easy to understand and I was performing experiments quickly. The experimental devices perform as expected and without difficulty. In every situation, the virtual lab behaved more or less as I would expect a real lab to behave.
