Girls on the Edge
9pm, BBC Two
This sensitive film documents the struggles of Jess, Erin and Jade, three girls who have been sectioned after self-harming. The root causes of their issues are varied: everything from the pressures of social media to government cuts is posited. But there is no doubting the courage with which they and their families attempt to tackle them. Alternately charming and crushing, there won’t be a sadder image on television this week than Jade clutching her teddy bear as she is transferred to an adult institution upon turning 18. Phil Harrison
Sea City
8pm, BBC Two
The agreeable, inessential tour of coastal settlements continues. Here, the Bristol harbour festival looms, with its big bands, lifeguarding dogs, and two nudists almost spoiling it. Before that, a new guy joins historic ship-mooring crew the Pill Hobblers, and the docks take delivery of an unusually wide load. Jack Seale
Young Sheldon
8.30pm, E4
Prequel following the formative years of The Big Bang Theory’s opprobrious polymath. It’s 1989 and Sheldon starts high school, his personality attracting more brickbats than bouquets. The show refreshingly relinquishes the urge to wring audience responses from every third line, but it lags behind other 80s-set sitcoms such as The Goldbergs. Mark Gibbings-Jones
John Worboys: The Taxi Cab Rapist
9pm, ITV
Taxi driver Worboys has lately become eligible for parole after spending fewer than 10 years in prison for rape and sexual assault. Police fear that his victims may number as many as 100; blunders on the police’s part may have allowed Worboys more opportunity to offend. Susanna Reid presents. John Robinson
From Ice to Fire
9pm, BBC Four
This week, Dr Helen Czerski concentrates on the band of the temperature spectrum in which life can function. While narrow when measured against the theoretical extremes, it is – as she demonstrates – sufficient to have prompted the evolution of many ingenious means for dealing with heat or cold. Andrew Mueller
The Job Interview
10pm, Channel 4
This week on the reality show, Yorkshire sausage merchant Heck is looking for a product developer. Food scientist Reza isn’t too hot on his sausage varieties, and industry veteran Stuart bungles the crucial taste test, so could wildcard pizza-restaurant manager Calum be the man for the job? Ben Arnold

Sally Hawkins is the irrepressible primary schoolteacher Poppy, pitted against Mr Angry driving instructor Eddie Marsan in Mike Leigh’s optimistic comedy-drama. It may not have the depth of, say, Secrets and Lies, but Poppy, by turns charming and infuriating, is irresistible. Paul Howlett
