Biodiversity: El Imposible National Park, El Salvador
Fifth graders explore the concept of how the more diverse an ecosystem is, the more interdependence of species exists within that system. The complex relationships among diverse species are difficult to identify. As species disappear or...
Curated OER
Endangered Species Problem
Students list the morphological characters used to identify the cacti in the field, and describe the associated problems in using these characters for identification. They draw the geographical ranges of the varieties of species...
