The Secret Life of 5 Year Olds
8pm, Channel 4
Another round of cute psychological experiments, sometimes with a mildly uncomfortable judgmental undertone. The theme of this new two-parter is right and wrong and, for a long time, one little girl has her half-formed understanding of the concept put starkly on display. But she comes good, as do the group as a collective when they are presented with a microcosm of economic inequality. Also offering chinks of hope for the future is the children’s assessment of Donald Trump: they all know who he is, and what he is.

John Robinson
The Split

Later Live … With Jools Holland
10pm, BBC Two
Jools Holland’s eternal music showcase is back and so is the anthemic bluster of Snow Patrol. Gary Lightbody’s lads take centre stage, but there are more visceral thrills courtesy of post-punky scallywags Shame, Detroit soul belter Bettye Lavette and Northumberland singer-songwriter Jade Bird.

Inside Out Homes
10.05pm, More4
From “garden cinemas” to sliding roofs, it seems the latest architectural fad is for blurring the boundaries between outside and inside. In this new design series, architect Zac Monro, engineer Monty Ravenscroft and plantswoman Rosie Bines aim to help homeowners live “inside out”.

Nostalgia (Andrei Tarkovsky, 1983) 1.15am, Film4
Russian director Andrei Tarkovsky ventured into the Tuscan hills for this meditative drama. It concerns a Soviet architecture professor whose research leads him into a friendship with a visionary Italian academic, living in a ruined spa.
