Last week Bristol ChemLabS, sponsored by the RSC's Analytical Division Western Region visited Poltair to give a hugely entertaining talk to Year 10 delivered by a postgraduate chemist. The lecture demonstration 'A Pollutant's Tale' was hosted by Tim Harrison who combined the knowledge of a super-scientist with the drama of a performing artist.

The lecture covered

  • The composition of the Earth's atmosphere in comparison to other planets
  • A brief description of the structure of the atmosphere
  • Investigation of some of the chemistry and properties of nitrogen and oxygen
  • A few of the tropospheric pollutants including carbon dioxide

Throughout the lecture there were demonstrations including some involving liquid nitrogen, oxygen foam, dry ice and a few explosions

Pupils expressed their enjoyment of the session with comments such as: "Amazing, I loved the liquid nitrogen being poured on the floor" and "I never knew chemistry was so fun and scary at the same time, the explosions made me jump".
