To operate the tutorial, first use the pull-down menu to select a sample for viewing. Next, use the radio buttons to rotate magnifications between 25X and 1000X to discover how increasing the magnification allows the microscopist to explore the details of minute features in the sample.

Important Note: Once all 6 magnifications have been downloaded locally to your computer, selecting between them will become much quicker because they already exist in your browser's cache.
