The document discusses an experiment that measured the respiration rate of mice (Mus musculus) at different environmental temperatures using a Qubit Vernier System. The researchers hypothesized that the metabolic rate of mice would increase as the temperature approached 15 degrees Celsius, while the null hypothesis was that a decrease in temperature would have no effect on the metabolic rate. Materials for the experiment included a Qubit Vernier System, temperature probe, ice bags, an animal chamber with fan, and mice. The document does not provide details about the results or conclusion of the experiment.
