Officials have confirmed that a Pinner school helped to set the world record for the biggest science lesson ever to take place.

Fifty Year 6, 7 and 8 students at Heathfield School for Girls, in Beaulieu Drive, took part in the record attempt on November 13, 2012.

They joined 2,000 other girls from 25 schools across the country in an attempt to set the record for the biggest ever physics lesson.

The Heathfield School students were shown an experiment demonstrating the effect of gravity on acceleration.

At the same time, the same lesson took place at each of the other 24 schools.

Anushka Patel, 10, said: “This experiment was such a lot of fun. I could not sleep with excitement at taking part in a world record-breaking attempt.”

Holly Brewster, also age 10, added: “I always read the Guinness Book of Records and I can’t believe that my school will be in the book too!”

Each school was required to film their lesson and to submit the video to Guinness World Records.

This allowed the adjudicators to establish whether a legitimate record had been set.

This was the first time that anyone has tried to set a record for the biggest multiple venue science lesson so the schools were hoping to have set a tough benchmark.

Anne Stevens, headmistress of Heathfield School, said: “The most disturbing statistic from the Institute of Physics’ recent report was that nearly half of all co-ed maintained schools in England do not send even one girl on to do physics at A-level.

“In the girls-only environment of Heathfield, science subjects in general, and physics in particular, are hugely popular and successful.

“At Heathfield School for Girls around 53 per cent of our girls study A-level physics or chemistry, and they do very well at it.

“The enthusiasm for this experiment, right across our school, shows the degree to which we’re bucking some of the less encouraging educational trends.”
