Seeing cell division via a movie on a laser disc player is more effective than having to look through a microscope. You're assured that everyone is seeing the same image from the movie, whereas students may see different things through a microscope. ToolBook Book A book is divided into pages, which represent the application's screen. A book is built by creating pages and by writing scripts which carry out the actions that you want the book to perform. A ToolBook book can be organized just like a real book.
Pages contain fields, buttons, and graphics known collectively as objects.
Objects are the building blocks that make up a book in ToolBook. A book itself is an object. It has properties such as a name, the number of pages it contains and the instructio ns, or scripts, that tell it how to respond. A page in a book is also an object. It has properties similar to the book as well as some that are unique.
