MORE than 200 people saw teachers lie on a bed of nails, dissect a bull’s heart and make raspberry ice cream using liquid nitrogen.

The dramatic displays were the climax of a week of activities to mark National Science and Engineering Week at Liskeard School.

The popular Science Show has become an annual draw for students and their families and friends.

Earlier in the week pupils from Liskeard’s partner primary schools watched Science teachers Mr Inger and Mr Trudgett demonstrate key principles relating to particles and energy using liquid nitrogen. 

‘The students were absolutely buzzing and left the show with some fantastic questions,’ said a school spokesperson.

Throughout the week, students took part in the school’s first Science Fair competition where they were given free rein to investigate a subject of their choice.

‘The Science Department has had some amazing entries involving everything from electrolysing water at home to finding the best method for making lead skeletons,’ the spokesperson said.

‘The students who took part have shown a real passion and enthusiasm for the scientific method.’

Ten youngsters also took part in a Physics and Drama STEM workshop at Exeter University with their teacher Mr Davis, and learned about the life of physicist Lise Meitner.
