Book 22: Tidal Communities: Interdependence and the Effects of Change

Levels: 3-4
Contextual strands: Living world icon. Living world

Synopsis

Most children in New Zealand have experience of, or access to, some form of coastal beach: rocky shores, sandy and shingle shores, mudflats, lagoons, or estuaries. These places offer a wide variety of habitats, where various tidal communities can get the food and shelter they need.

Studying this environment gives children opportunities to explore concepts of:

  • the variety and interdependence of living things
  • the effects of change, both short- and long-term, on an environment
  • the relationship between living and non-living elements in an ecosystem.

The topic is also a context for incorporating an awareness of Māori values associated with kai moana. Beaches are places of great importance to Māori as sources of food, and there are various protocols through which respect is shown for an environment which, through these sources, helps to sustain human life. The concept of inter-relatedness is particularly relevant here. This concept has physical, emotional, and spiritual dimensions in the Māori world. These can be applied to the study of this topic to enhance an understanding of interdependence and the idea of kaitiakitanga (people's responsibilities as guardians of their environment).
