Before the lesson, the teacher should copy the data tables found in Figures 2 and 3 (on the website) and paste the tables to a student worksheet so that the students have a place to record their data.
On the back of the worksheet the teacher should copy and paste the three after-activity questions found next to Figure 3 on the website.
Once all individual data are recorded have participants share their data in a way that all participants can observe (on a large white board) so that a class average can be calculated.

At the end of the activity the groups may eat their M&Ms.
