On one of the first class periods of the year, students are paired-off and given a lab-based puzzle to solve. One in each pair is given a set of three colorless solutions, designated with numbers, the other is given a matching (but scrambled) set of solutions, designated with letters. Through careful mixing, observing, reporting and reasoning, they work together to pair up the lettered solutions to their matching numbered solutions.
