This webpage from SERC features GEOLogic questions, which are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills. In this example, students are asked to convert measurements in cubic feet per hour (cfh) to cubic feet per second (cfs) and then match up the names of the researchers measuring the flows at the river station with the correct flow rate. There is also a second part in which students graph the different flow rates with time and answer questions by interpreting the information in the graph.
