Free things to do in London this week.
Do half term on the cheap
With children off school this week, parents and carers will be needing our things to do in half term guide. It's packed full of shows, events, exhibitions and activities, and — helpful if you're on a budget — has a whole section dedicated to free things to do for all ages.
See this thought-provoking environmental exhibition
This week is your last chance to see Water Pantanal Fire, a free photography exhibition by Lalo de Almeida and Luciano Candisani, at the Science Museum. Focus is on the Pantanal, the world's largest wetland which is spread across Brazil, Bolivia and Paraguay.
More than 60 images are on show contrasting the Pantanal's rich wildlife with the drought and wildfire damage threatening the region. As it's half term, the museum will be very busy so booking in advance is strongly recommended.
Until 31 May.
Get your fill of football shirts
The London Jersey Gallery stages the final week of its independent pop-up exhibition, From Woolwich to the Emirates – 140 Years of Shirts, at the Weaver's Arms in Canonbury.
Curated by football historian Abdul Rashid Zakari, the free display brings together historic kits to show the evolution of design, notable eras and collectors' culture, while exploring the history of local team Arsenal.
Until 31 May.
