There is an ongoing multimedia project that is part of the seventh grade science curriculum at the Baker Demonstration School at National-Louis University. They then spend several sessions at the zoo observing this mammal's physical characteristics, behavior, locomotion, and its zoo habitat. These observations become the raw data for constructing a multimedia presentation about their mammal. It also allows you to incorporate other forms of media such as a laser video and music as well as text. You can also scan in photos, drawings, and postcards.
Every screen is called a card.
Every card is linked somewhere else in the stack. This is a good idea because it allows you another form of expression other than a book. It organizes ideas by associating them with more general ideas. HyperCard is better for organizing ideas than a regular word processor because it works by association. If your information is organized by association it's easier to understand.
