Next Generation PET Table of Contents

There are both small class (SC) and large class (LC) versions of Next Gen PET. Although the names of the activities (A) for the SC version and lessons (L) for the LC version are mostly the same, the SC versions take 2-3 times longer to do in class than the corresponding LC versions. A SC period is about 2-3 hours long, while a LC period is about 75 min. Extensions (Ext) are online homework activities.

Most lessons share the same number as the corresponding activity; when they don't, the lesson number is indicated by L# following a forward slash (/). A few lessons, activities, and extensions are intended for the large class or small class only. These are indicated by [LC only] or [SC only] in the right column.
