The Perse School celebrates moles of the chemical variety


Yesterday (Wednesday), pupils at The Perse School in Cambridge celebrated Mole Day with a series of fun and interesting activities focused on the mole – a useful unit of measurement in chemistry.

A mole is the amount of any substance that contains as many elementary particles - atoms, molecules, electrons, etc - as there are atoms in 12 grams of pure carbon. The number is approximately 6.02 times 10 to the power of 23, or 1 with 23 noughts. As 6.02 corresponds to 6th February, the School has adopted the date as their ‘Mole Day’. 
While the aim is to help students understand the importance of the chemical ‘mole’, many other mole-related activities brought the concept to life, from sporting to artistic. During the day, pupils at the Upper School were set a range of experiments and challenges including:
·     Mole experiment circus
A lunch-hour session of simple chemistry experiments all related to a mole (a unit)
·     Make a mole
Prizes were awarded for the best entries to the ‘make a mole’ competition.
·     Guess the number of moles in a balloon
Pupils were challenged to correctly guess the number of moles of gas in a helium balloon carried around the school at break and lunch.
·     Moleympics
The sports department ran a MoleBall tournament (a variation of a dodge ball, but with a distance being set at 6.02m)
·     Mole hunt
Pupils visited various departments around the School to find answers about moles relevant to the subject, for e.g. in the biology classroom there was a question about the animal species
Even the catering team got in on the action by creating mole-themed dishes such as Chicken Mole Poblano, a Mexican dish with chili and chocolate, and ‘Caramole’ pudding.
Head of Chemistry, Dr Tanya Khimyak, said: “Mole Day has been lots of fun and it’s been great that everyone from the sports department to the catering team got involved, with the new School sport of ‘Mole ball’ proving particularly well-supported. It’s been a really enjoyable way to get an important scientific point across, and I doubt anyone at The School will forget what a chemical ‘mole’ is in a hurry!
“Vitally-important ‘STEM’ subjects – science, technology, engineering and mathematics – are some of our most popular subjects at The Perse. Mole Day extends pupils’ classroom learning, fuelling their interest and helping to inspire and equip them to take on roles in Britain’s research and development industry in the future”.

About Mole Day
Mole Day was created in 1991 as a way to foster interest in chemistry by a chemistry teacher in the United States. Schools throughout the United States and around the world now celebrate Mole Day with various activities related to chemistry and/or moles. Due to the American way of presenting dates, Mole Day is traditionally celebrated on October 23rd from 6.02am to 6.02pm.For more information, see:
