Once I am sure that students understand the mechanics of manually plotting a graph, I have them analyze their data using this program. Experimenters can input the variable they have studied and determine the shape of graph that best fits the data. It is easy to manipulate the data and explore squared or inverse relationships. From this exploration, the mathematical equations so familiar to traditional physics students are developed. Similar analysis can be done with graphing calculators but the Graphical Analysis software program makes it easier to get a printout of the graph or incorporate the data table and graph in a lab report of the experiment's results.
Students work collaboratively on preparing the boards.
The can show what they've identified in their labs, or to show solutions to various problems. The groups then present the information to the class for discussion. Students defend the experimental procedure, show their analysis of data, present solutions to problems, and discuss identified models with their classmates.
