These activities address National science and technology standards, as well as specifically focusing on mathematics content and process standards. There are ten missions and three exploration extensions that provide activities for up to one semester. These activities are geared towards using a graphing calculator with a Norland Research calculator robot. Best results for student engagement have been obtained with each student having her/his own CalcBot (calculator + robot) to use in class. The curriculum is suited for mathematics, science, technology, or after- school classes.

It is an effort to still cries from those who have asked for a comprehensive listing. The Special Publication series, which has included some of NASA's most ambitious scientific or technical books, has covered a broad range of topics, including much of the agency's research and development work, its full range of space- exploration programs, its work in advancing aeronautics technology, and many associated historical and managerial efforts. In the nearly two decades that the series has existed, some 1200 titles have borne the SP identifier. How NASA Special Publications came about may be instructive. Along with several predecessor agencies, NASA research laboratories were accustomed to publishing reports, using a formal structure of four or five separate series, with the characteristics of each series carefully defined. Inevitably this raised the question, how do you categorize reports that don't fit existing patterns? The answer, obviously, is that you put them in another series labeled "special." The backroom gnomes who invented this solution had no knowledge that they were inventing a bushy tail that would soon wag the dog. By the mid-1960s the new series was becoming preeminent among NASA publications, and.beginning to win worldwide recognition.
