Earthquakes and seismology might not seem like the obvious solution, however Ben is from Oakham in Rutland, which due to a spate of 9 earthquakes in 2014-15 earned the dubious title of "earthquake capital of Britain"
Unfortunately the earthquakes (maximum magnitude 3.8) were missed by Ben who was either asleep or on holiday when they all happened, so he was quite excited to learn that Oklahoma had since 2009 become the "earthquake capital of America"
So Ben agreed to become a "roving schoolboy seismologist" for the UK school seismology project, (an educational outreach project run by the British Geological Survey) and to monitor any unusual seismic activity going on in Oklahoma during his stay.
