Geological Survey NSW will present a fossil rock workshop for kids at Kurri Kurri Library on Tuesday from 4pm to 5pm.

Kids will be able to check out fossils, rocks and maps. There will be a fossil dig, paper models of ancient sea creatures and volcanoes, and colouring-in, and participants can even make their own fossil to take home.

Geological Survey NSW will give a free talk for adults, titled What Lies Beneath - An Introduction to the Geology and Rocks of the Hunter Valley Area, at Cessnock Library on Wednesday from 6pm to 7pm.

Then on Thursday, Alex Morris will give a talk on climate change at Cessnock Library from 5.30pm to 6.30pm.

Morris is a member of the Climate Reality Leadership Corps who recently attended Al Gore's Climate Reality Conference in Brisbane.

Council's library services coordinator Rose-marie Walters said it's exciting to partner with Climate Reality Corps and Geological Survey NSW to offer these engaging and informative activities.

"National Science Week is Australia's annual celebration of science and technology. It aims to encourage an interest in science pursuits among the general public, and to encourage younger people to become fascinated by the world we live in," Ms Walters said.
