Dr Joe McGinnis, a senior lecturer in the School of Science & Engineering, is among University staff involved. He will deliver a chemistry demonstration.
He said: 'Chemistry plays an extremely important role in our everyday life, often in areas you might not think of. Most of the clothes we wear are made from synthetic fibres which are products of the chemical industry.
'This event allows pupils to see how chemistry is involved in a wide range of different industries, and hopefully inspire many of them to pursue their study of a subject which will provide them with many fascinating opportunities for a future career.'
Leila Elliott, of the Royal Society of Chemistry鈥檚 海角直播 Local Section, said: 'The feedback from students, teachers and presenters about Chemistry at Work indicates how worthwhile they find the event. The representatives from companies and education believe in contributing to the development of the region's young people. They hope that many students will see the benefits of pursuing further studies in the subject which will give them access to a wide range of fulfilling and rewarding careers.'
