A small room in the Sarjeant Art Gallery on Taupo Quay is a hub of Kakaramea School pupil activity.
Inside, they are planning how to create their dioramas, they're taking instructions, cutting shapes and working together to create the best dinosaur that they can.
Almost 50 pupils from the primary school in Patea have made the trip to Whanganui as part of their trekking through time inquiry project.
Kakaramea School teacher Kylie Manson said the next stop will be the Whanganui Regional Museum.
"We're going to go and look at bones and fossils there, so that ties in nicely. We're trying to link things as much as possible," Manson says.
