Analyze air pressure data from a smartphone or tablet
It turns out nearly all smartphones (iPhones and Android models) and nearly all iPads have air pressure sensors (a.k.a. barometers). There are a couple of apps you can use to get a pressure reading but the one that seems to work best on all platforms is the Arduino Science Journal app. The goal of this activity is to use the air pressure sensor in a smartphone to collect pressure data at different heights and compare the data to known physical models.
