Take It Back to the Classroom

 

This project can be adapted to your particular teaching situation on a variety of levels. You do not need to be in a Costa Rican tropical dry forest to allow your students to investigate exotic invasive species. Contact your local conservationist group to find out which exotic invasive species may be in your region.

 

Quick In-Class Activities

  • Transect studies of the species diversity within the school yard and football field vs. the area beyond the school yard and football field.

 

Off-Campus Field Studies

  • The methodology described above can be applied to any outdoor local ecosystem on or off-campus. Take students to the campus quad, agricultural area, a local city or national park or wildlife preserve and select organisms to study.
  • Data other than population may be taken in an attempt to find correlations between population distribution and exotic invasive species as was done in the "The Effects of Introduced Exotic Grasses on Tropical Dry Forest Regeneration" study.
  • Students may investigate water quality, soil quality, or other abiotic factors that may influence organism populations.
  • For technical and/or possibly financial support, contact the regional EPA office in your area, local conservation groups, the National Park Service, a nearby university, or the department of natural resources. You will find many institutions are eager to help train students, lend equipment, and/or provide transportation for student fieldwork.

 

General Tips for any of the above activities:

  • The in-class or schoolyard activities can be used to prepare your students for an upcoming field trip.
  • Scout locations for field studies in advance to recognize problems the students may face when conducting their study.
  • Plants are great subjects for fieldwork as they are immobile!
  • Make sure that you and your students are ready to make adjustments to your methodology on the fly, as field studies are often unpredictable.
  • Have fun with it!
