Fifty girls at a Pinner school took part in a world record breaking attempt this morning.

The Year 6, 7 and 8 students at Heathfield School for Girls, in Beaulieu Drive, joined 2,200 other girls from 25 schools across the country in an attempt to set a new world record.

The students were attempting to break the record for the biggest multiple venue science lesson ever to take place.

At Heathfield School all fifty girls gathered in the sports hall at 11am for a physics lesson.

They 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.

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

This will allow the adjudicators to establish whether a legitimate record has been set.

This is the first time that anyone has tried to set a record for the biggest multiple venue science lesson.

Therefore, the schools hope they have set a tough benchmark for anyone who attempts to beat them.
