Dunes

Nature

Level: 2

Requirements

  • What are dunes? What is the primary ingredient?
  • Name four items needed for dune formation.
  • Explain the following three ways that wind moves sand.
    • Surface Creep
    • Saltation
    • Suspension
  • Explain the following dune formations: Barchans, star dunes, Linear or Longitudinal dunes, parabolic.
  • What is Ecological Succession? How is this demonstrated in dune communities?
  • What is Dune Blowout? How does it relate to Succession?
  • What are pioneer plants? What is their purpose in dune communities? Give two examples.
  • Give three examples of plants in dune environments. How are they adapted for survival?
  • Give five examples of animal species in dune environments. How are they unique for living in dune communities?
  • Discover an early pioneer of dunes management and conservation within your conference, union, or division. Share your discovery with an instructor or group.
  • Tell a story about sand and draw a spiritual lesson.
  • Do at least two of the following activities:
    • Visit an exhibit or conservatory of desert plants/dune plants. Look for how they are adapted to living in sand or poor soil, harsh temperatures and lack of water.
    • Visit a zoo where there are desert animals, especially ones that are adapted to living in sand. If possible, observe some of the ones you studied while learning about dunes.
    • Watch a video about dunes or plants or animals that live in dunes.
    • Construct an outdoor working demonstration of dune progression using sand, an object for obstruction, a fan to blow the sand. Observe how the sand blows over the obstruction and falls on the other side forming a dune.
    • Draw or paint a picture of something you had fun learning about while studying dunes.
    • Talk to your group, write about or make a short video about a real life dune conservation project. Explain why this specific habitat should be saved, i.e. endangered species of plants and/or animals living there.
