During the event, the children had to solve a mystery which involved testing salts to identify elements, then use this to solve a forensic puzzle by working as a team.
Audrey Strong, of the Salters鈥� Institute, said: 'For the children, visiting a university lab is very different to a school lab and events such as this help to give them more time than they might have in school lessons to work through experiments.'
Rebecca Kitchener, 13, of Bydales Technology College, Marske, said: 'We鈥檝e been looking at chemical reactions and it鈥檚 been really good. I鈥檓 really interested in chemistry and I鈥檝e enjoyed doing the experiments.'
Maria Ghafoor, 13, of Macmillan Academy, Middlesbrough, said: 'I鈥檝e really enjoyed the experiments which involved flame tests to find the non-metal and metal parts of salt.'
Edward Day, 13, of Carmel RC College, Darlington, said: 'We have been mixing chemicals together to see what happens, it鈥檚 been really fun. It鈥檚 been great using the University鈥檚 labs, they are really big and there鈥檚 so much equipment. I鈥檓 really interesting in studying at university, doing something in maths or science.'
Also held recently at 海角直播 was the Chemistry at Work event, sponsored by the Royal Society of Chemistry, Cleveland Scientific Institution and PerkinElmer.
Representatives from the region鈥檚 industry, education and hospitals delivered demonstrations and presentations in diverse subjects ranging from industrial manufacturing processes to forensic chemistry and biochemistry to show the importance and applications of chemistry to daily life.
Participants include Tata Steel, BOC, Northumbrian Water, 海角直播, James Cook University Hospital, North Tees University Hospital, Fujifim Diosynth Biotechnologies and GSK.
Among those taking part was Kate Nevin, 13, from St John鈥檚 School, Bishop Auckland. She said: 'It was really interesting hearing all the different presentations and getting involved in the different experiments.'
Leila Elliott, of the Royal Society of Chemistry, 海角直播 Local Section, said: 'I鈥檝e been involved in Chemistry at Work at 海角直播 for 15 years and want to express my gratitude to everyone who has been involved in its continued success, from technicians in the University鈥檚 School of Science & Engineering to academics and the University鈥檚 catering staff. The feedback from students, teachers and presenters indicates how worthwhile they all find the event.'
