Students in our major/minor programs generate a class hypothesis using summarized research on soil respiration and vote on a treatment option: soil type, litter type, water levels or temperature. Respiration chambers incubate for a week, and the amount of CO2 produced over the seven days is determined the following week. This is an easy, low tech way to teach these concepts, but could be adapted to use probes to measure CO2 directly. This activity is very adaptable to highlight different skills such as hypothesis testing, statistical analysis and experimental design. In institutions with more space resources this could be easily adapted for more inquiry-based approaches.enAll Rights Reservedclimate changecarbon cyclingecologyhypothesis testingPresentationhttps://doi.org/10.37590/able.v41.art13
