This lesson is motivated by a respiration study using a FLIR ONE™ thermal camera in conjunction with the Vernier Thermal Analysis Plus app. Using Voyager and the PocketLab Temperature Probe, however, allows students to investigate respiration at a fraction of the cost of a thermal camera. The response time for the Temperature Probe is rapid enough to observe temperature differences in the air inhaled and exhaled through the mouth during the process of respiration. In addition, by using the PocketLab-Scratch Beta Integration platform, students can be encouraged to design a Scratch program that shows a lung in the form of a sprite growing larger while inhaling and smaller while exhaling.
