SCHOOLCHILDREN were treated to tales of a wintry adventure when they met a mountaineering expert who has recently returned from Antarctica.

Jonathan Bursnall visited the continent as part of the British Antarctic Survey.

And this week he stepped back into his cold-weather clothing at the Yorkshire Museum, in York, where he talked to pupils from city primary schools about everything from the creatures that live there to the food that is needed to survive.

The event was the first Children's Christmas Lecture organised by York Museums Trust.

Pupils were also given the chance to take part in a range of hands-on science activities including ice core sampling, counting tree rings, handling ice age fossils and excavating a woolly mammoth skeleton.

The Yorkshire Museum is currently running an exhibition called Ice Age, which takes visitors through different Ice Age landscapes from the past two million years.
