Analysis of data obtained in the Boyle's law experiment (video here: https://youtu.be/J9IoAp51_7w) in which the relationship between gas pressure and volume at constant temperature for a fixed mass of gas is investigated. Boyle's law is one of the key foundations of the ideal gas law and so this experiment is relevant for GCSE science, A-Level physics and A-Level chemistry.
You can download the worksheet to try the analysis yourself - great for learning independently at home: https://physicshq.wixsite.com/alevelphysicshq/resources-linked-to-videos
Relevant concepts: Boyle's law, gas laws, ideal gas law, gas pressure, gas volume, direct proportionality, inverse proportionality, and testing for proportionality.
