From the Introduction…

The purpose of this activity is to develop students’ ability to conduct scientific inquiry by having them (1) make observations, (2) establish consistent criteria for data collection, (3) represent data graphically, (4) interpret graphs, (5) draw conclusions and inferences based on a limited data set, (6) effectively communicate results to peers, and (7) learn about the nature of science. The activity employs five instructional strategies: teacher-guided discussion, hands-on data collection, collaborative learning, graphing-to-learn, and oral explanation.
