Geyser model with real-time data collection

The physical model of geyser oscillations presents a challenge to experts, even under relatively simple and clear laboratory circumstances. Despite complex dynamics a qualitative analysis can be made based on video recording and real-time temperature and pressure measurements. The simple experiment with Geyser model is rich with several phenomena from the field of thermodynamics that are included in basic and advanced physics course. The measured values can be shown to be in consistence with the basic theoretical considerations. Geyser project can be fun and attractive and can be fruitfully used to stir up student’s interest.
