Abstract

<jats:title>Abstract</jats:title> <jats:p>During the COVID-19 pandemic and subsequent lockdown, both schools and universities faced significant challenges in moving teaching from an <jats:italic>in-situ</jats:italic> setting to a remote one, this included laboratory experiments. This paper presents an experiment developed to use a phone’s in built pressure sensor, common to most smart phones. By using this sensor to measure the pressure at a series of known heights, the density of air was calculated with an accuracy of approximately ±0.03?kg?m<jats:sup>-3</jats:sup>. This was completed as part of a first year undergraduate course.</jats:p>
