Overview: Threatened and Endangered Species.

In this unit, students are introduced to the fundamental significance of these categorizations, and acquaint themselves with Hawaiian animal and plant species listed under each of these categories. This provides the supporting background that sets the stage for student expert pair group investigations in subsequent lessons. Through textbook readings and class instruction, guided online searches, and PowerPoint presentations, students find that changes in environmental conditions come from natural causes or human activities, or a combination of both. Environmental changes may cause decreases in endemic populations of plants and animals, or could also increase invasive species populations.
