Disturbance in marine ecosystems-Concept mapping
Target Group: Secondary School
Subject: Coral Reef Life
Ocean Literacy Principle: 2,4,5,6
Students make a concept map of a marine ecosystem in which they show the effects of disturbances on the ecosystem, for instance coastal development in the mangroves.
Students brainstorm with the whole class which human and natural threats occur at different marine ecosystems. They pick an ecosystem in small groups and think about the effect of two disturbances. Classmates give suggestions after which each group makes a concept map. The map shows the impact and effect of the disturbances on their ecosystem. Applying knowledge in this activity can best be done after the activity 'Coral reef succession'.
