Lesson description

The Coastal Management programme has both an interactive indoor session, and a practical, hands-on session where students will be outside on the beach.

Students will have the chance to enter a debate considering the future of the coastal environment taking on the perspective of a wide range of community members.

Consideration will be given to the consequences of our interaction with the coastal area (past and present) and the variety of ways we can minimise our impact on this environment.

Students will build a mini-dune system and beach profile. They will work with a coastal park ranger to manage their beach area; learning about and using a variety of coastal management techniques, including sand fences, vegetation, groynes, gabions and sea walls.

Students will also have a chance to make their own mark in protecting and enhancing the environment, by participating in a beach clean-up or dune planting exercise, depending on the time of year.

An option is available to introduce your students to the ecological processes at the beach specifically focusing on the botanical biodiversity present. Please include this request in the 'Additional information' box in the booking form.

Learning outcomes

We are learning to:

  • Identify key reasons why coastal environments are special places.
  • Explain how people have used the coast and how the coast has changed from past to present.
  • Name at least three techniques used to prevent and reduce coastal erosion.
  • Identify at least three interest groups related to dune management in the coastal region and name at least one of their interests or concerns with how the dunes are managed.
  • Identify an action that they can take to reduce dune erosion.

Key competencies

Using language, symbols and texts

Students will interpret images, symbols and text to understand the dynamic nature of Christchurch’s changing coastline.


Students will use critical and evaluative processes to reflect on and re-evaluate their ideas and values surrounding contemporary coastal issues.

Managing self

Across a variety of collaborative learning activities, students will manage their learning and behaviour and act in an appropriate and safe manner.

Participating and contributing

Students will join a discussion around their values and opinions of coastal issues and be expected to explain or expand on their ideas.

Relating to others

Students will work collaboratively and supportively to complete tasks; listen and share opinions and ideas, and support their classmates.
