Group activity

Duration: long-term project

Type of activity: modelization, experiment

Language: English

Materials required: biodegradable materials (such as old coconut leaves, mats, sticks, driftwood, dead plant material) and sand

Together, participants will have to find the ideal location to build this sea wall. They will have to use biodegradable materials and pile them up to build a solid foundation.

Natural sea walls are made of biodegradable materials that help protect the coast from erosion caused by rising sea levels and wave action.

The activity sheet provides the complete protocol for the activity. It ends with a discussion section to build on the knowledge gained during the project.
