MentosCokeLab Post-Action Report

As close to a perfect lab as I’ve ever done! Minimal instruction from me, clear directions on the board, and adequate supplies easily available reduced the number of “What am I supposed to do now?” questions. The kids were really into it, very engaged, and focused on the process and result. I used 12-oz bottles of soda, a single piece of candy in each bottle, and a plastic bucket for each team, so the mess was an absolute minimum. The key was to split the class into two large groups: one group held the soda constant (diet coke) and tried different candies; the second group held the candy constant (mint mentos) and tried different sodas. The control for the candy was a marble, and the control for the soda was an equal volume of water. Lab report due at the end of class was hand-written, and had their hypothesis, methods, or procedure, a data table, and a short conclusion. I graded this at a “D” level: what we call “Developing” proficiency, as opposed to “Initial” (first exposure), or “Comprehensive” (broad and deep proficiency). You should be happy with a 3; a 4 means that you really impressed me. Out of a 1-4 scale.
