Oh dear! King Aquamarine has forgotten the code to his treasure chest. Help the wizard Calcitus solve the four calcite puzzles. Join forces to search for one of the most common minerals on Earth and discover its properties and what it can be used for. In the hands-on ‘Research Expedition’ lab, you can not only open the treasure chest but also carry out some brilliant experiments with calcite.

Our holiday programme guides you through our exhibition and ends in the hands-on lab ‘Research Expedition’.
The holiday programme is an open activity for the whole family in the form of a treasure hunt. It is included in the admission price. You can start it at your own pace. This activity does not take the form of a guided tour at fixed times.

Suitable for children aged 7–12; younger children will need help from parents, grandparents or siblings.

No booking is required. After-school clubs and children’s groups are asked to register at the information desk: 03731 394654 or fuehrungen@terra-mineralia.de
