The Data Dilemma© activity is designed to model the practice of science in which scientists must incorporate new evidence into a working model of their research topic. Teams of students will use the 5 tangram pieces progressively to build larger triangle models. When new data won't fit the triangular model, your students will need to change their model into a geometric shape with the fewest possible sides.

The Data Dilemma© Scenarios

Find several different scenarios you can use to facilitate a discussion on how scientific models evolve. Students will model the process of incorporating evidence into a working external representation of the data, as you walk through a scenario.
