Finding resources
Sometimes you find resources that can be downloaded as a zip file or as SCORM.
SCORM stands for Shareable Content Object Reference Model and it means that the resource you want is bundled into a package that can be easily loaded onto Moodle. The entire package usually retains the contents pages, navigation, and index.

Some sites use Zip files. These are easy to load into Moodle.
