PBS Teachers Activity Packs
PBS Teachers has some great activity packs for teachers to use with their classes.
They have packs in arts, health and fitness, reading and language arts, science and technology, and social studies.
The activity packs have PBS resources, such as videos of PBS shows like NOVA, web links, and lesson plans for each topic. There are activities for different grade levels also.
These packs are great ways to have a multimedia, project based lesson for your class.
