Over the years, blimps have assumed many role including transportation, military surveillance and advertisement. Through all of these duties, they have held the fascination of the people observing them.
The Web site for Floating on Air has an overview of the video and a pre-viewing activity. In the activity students form groups with each group becoming an expert on one aspect of the blimp and then sharing that information with the class. The site also includes a blimp timeline, a glossary of terms, information on the laws of science that govern the flying of the blimp and exercises using those laws, a resource hotlist and two activities involving students using helium to perform experiments.
