Invasive Species
An invasive species is an organism that is not native to an ecosystem, and thus has no natural predators in that environment. This lack of predators often causes some wicked problems in the place it colonizes. With no predators, these invaders can out-compete local fauna and flora, and then disrupt the balance of the ecosystem. You might be wondering, how do these species get to their new location? Well, some are introduced purposely by humans, such as the European hare which was brought to Australia in the 1830s, and some are introduced by accident, like the emerald ash borer, which has wiped out native ash trees in the Midwest and the Eastern United States. Explore the new worlds of these alien species with this collection of resources.

Definitions in the Field
Concepts like chlorophyll or urbanization can be hard to explain. Watch as experts like National Geographic Explorers easily translate difficult terminology into an understandable form, while standing right in front of the phenomena in the field! The videos in this collection feature explorers in the field teaching difficult topics they study everyday.

Big Cats and Their Habitats
Students use media resources to identify big cats and map the species ranges of the world's big cats. Then they determine each big cat's corresponding habitat and create a graphic organizer that summarizes the information.
-
Conservation and Big Cats
Students read a National Geographic Education article, “Big Cats’ Big Problem,” and identify the threats to big cat populations and how the National Geographic Big Cats Initiative is working to address those threats.
