Exotic Adventures

Activity 1

  • Teacher prints Schools Ground Survey Form from this site.
  • Students survey school grounds for invasive plants, record the data, and give survey forms to teacher.
  • Teacher enters data on Web site. [Data Entry Form]
  • Students monitor Web site periodically to compare their findings to those of other schools.

Activity 2

Have students choose and research a particular species (using this Web site or others listed under Resources).

More Exotic Adventures

  • Students survey their yards or local parks and discuss what these species have in common (i.e., habitat, proximity to humans).
  • Students develop methods for removing and discouraging invasive species from school grounds.
  • Students look for the following species that have the potential to become invasive in North Carolina:
    • Salvinia (water plant)
    • Gypsy moth
    • Fire ant
    • Hemlock adelgid (insect)
    • Rumina decolata (land snail)
    • European earwig
