Housing some of the world's most significant fossils and already home to dozens of interactive activities for children the new attractions add to the museum's learning opportunities depicting how fossils tell us about the different kinds of organisms that lived on the earth and how they have replaced one another over geological time.

The Spinners, located in the museum grounds, depict organisms from each geological period.

Each spinner looks like an image of a fossil from that period.

Installed courtesy of grants from IGA and Newcrest Mining the $18,000 Spinners will be officially unveiled on February 28.

"They're just to make it more exciting for kids," museum manager Anne Clark said of the new additions.

Installed at the end of the school holidays Ms Clark said the Spinners are less than a metre and a half tall and designed not to spin too fast but at the same time are easy for the children to spin.

"We thought we needed something that showed organisms from the different periods but weren't boring," she said.

Ms Clark, who has a teaching background said the Spinners are a perfect learning tool for children.

Kids are concrete learners," she said, learning best with hands-on methods, doing rather than watching.

The Spinners add to what Ms Clark describes as Canowndra's internationally significant Age of Fishes Museum.

"What we have here is evidence of the first life moving from water to land," she said.

"Most people in our own area don't realise how important the fossils we have on display are."

Earth and environmental science is presented at the museum in an easy to follow and entertaining way, designed to engage students' imagination and increase their skills in observing measuring, interpreting, communicating, researching and recording. The new installations enhance this learning even further.
