This booster explains the parts of the microscope and their function, and concepts such as Magnification, Contrast, Working Distance, Resolution, Field of View, and Depth of Field. You will discover how to successfully focus and view a specimen using progressively higher magnification lenses, including the additional steps that using the Oil Immersion Objective Lens requires. These files are SCORM packages and can be easily uploaded to your Learning Management System (LMS), such as Blackboard or Desire2Learn. If you want to view or use the files without an LMS, download the files to your computer, extract (unzip) the file, open the extracted folder, and click to open the story.html file. The booster or test will open in your browser window. If used on your LMS, for the booster, the user will be given a score of complete or incomplete; for the pre and post-tests, the user will be given a numerical score. This scoring functionality and completion data is only available if used on an LMS. The SCORM packages are complete and not available for editing. If you would like to include additional information, consider adding the content before or after the booster on your LMS.
