Eureka!, the national children's museum in Halifax, Yorkshire, is to unveil a new £2.9m health and body-themed gallery on 29 March 2013.

Entitled All About Me, the immersive educational experience is the largest single gallery redevelopment in the museum's 21-year history.

It will use play, role playing and interactive displays to help children learn about their bodies and how to make positive choices that will help them look after themselves.

Featuring more than 100 interactive stations, the exhibition has been developed with the support of a £1.45m grant from the charitable foundation Wellcome Trust.

Gallery content and interpretation was designed by At Large and was guided by a team of expert advisors from academia, the medical profession, education and local government.

The new space will open at a time when even greater focus is being placed on the health and well-being of children and families. Government figures predict that 50 per cent of the UK population will be officially obese by 2030.

Leigh-Anne Stradeski, Eureka! CEO said: "All About Me will help hundreds of thousands of children across the UK build the knowledge, confidence and ability to make healthy choices about what they eat, drink and do in their free time.

"Not only will this make their childhood more enjoyable but it will pay dividends in the future by reducing risks of heart disease, diabetes and stroke."
