Three young women go back to school to find out what turns girls away from physics, asking what can be done to improve the situation.
By the time they reach A Level, over three times as many boys as girls are taking physics, resulting in under-representation for women in occupations involving science, maths and engineering.
Particle physics PhD student Rosie Walton, magazine feature editor Laura Kennedy, and engineer Michelle Dowling observe two Year 10 physics lessons at Haydon School in London.
The three observers later discuss the lessons with pupils to find out their thoughts, and feed back their findings to the teachers.
