The children are transported to the excavation site of the Petrified Forest of Lesvos along the road Kalloni – Sigri. Through a research route along the new road, they observe the works carried out at the construction site of the Petrified Forest, discover information about the conservation works and their results, identify and record the tools. At the same time, they identify and map the fossils, rocks, volcanic, tectonic and geomorphological structures, which they encounter.

The program includes:

• Discussion about the work of the researcher – geologist, the fossil conservator, the excavation and conservation worker.

• Discussion on basic concepts such as fossil, rock, mineral, fold, mapping, excavation, conservation, fossil transport.

• Gathering information on the fossilized plants that have been identified along the new road Kalloni – Sigri.

• Discussion on the process of mapping, excavating, preserving and transporting fossils.

• Discussion on materials and tools for excavation, conservation and transport of fossils.

• Participation in mapping, cleaning and conservation of plant fossils.

• Recording the findings in the special educational cards.
