I remember arranging for the international meeting during my tenure so vividly because I mailed the important question sheet about arrangements meant for the Middle Eastern University to the one in Europe.
For this activity from veteran school librarian Pat Miller's Stretchy Library Lessons: Research Skills (UpstartBooks: 800-448-4887), you need only a copy of the following question sheet for each student pair, strips of paper, pencils and either a CD-ROM version of an almanac or a bookmarked almanac site on computer workstations.
Information and interaction are so integrated that the information does not take additional room on the question sheet. The student can click any keywords in the problem either before or after making a choice.
For three rounds, groups see a different question sheet each time, but on the fourth round (since there are only three different sheets of questions), the same questions they had the first time come back to them.
