Extreme characteristics can create some unusual mammals. Learners flip through a slide show of some of the most interesting mammals that are both living and extinct. Implement as a remote learning resource or use in-class to review...

Young environmentalists consider how scientists are attempting to save endangered species. They read about what causes extinction and steps to take to minimize the threats. 

DNA analysis could be what saves some animals from extinction. An interactive lesson shows learners how DNA information proves variation among animals of the same species and how stakeholders use that information to make decisions. Easy...

A mammalogist, ornithologist, ichthyologist, and a conservation geneticist share their work and their hopes that their research will help protect and save endangered species and their habitats.

Not all dogs are the same just like not all finches are the same. An interactive online lesson helps individuals learn about the causes and limitations to biodiversity. The clickable sections describe the basics of the genetics of...

Who doesn't want to know more about the mysterious dinosaurs? Learners read about dinosaurs and the process scientists use to continue learning more about the animals in an interview-type format. A paleontologist responds to submitted...

Early humans crafted shelters out of whatever materials they could find. A one-question quiz asks learners to identify the type of bones used to construct the hut pictured in a display.

Some dinosaurs get all the attention. Pupils use an interactive resource to study some of the lesser-known dinosaur species. Organizing the information in a cladogram allows learners to make connections among the species.

Get ready for an explosive lesson! Learners read and interact with an online lesson describing the characteristics of volcanoes. They study specific historical volcanoes as well as the science of volcanic eruptions using animations and...

A famous fossil of fighting dinosaurs holds as many questions as answers. Scholars first analyze the fossil itself by virtually highlighting the specific bones of the dinosaurs and read about their function and importance. They then test...

This is the opening site for the online exhibit at the Natural History Museum. The exhibit features a wealth of information on dinosaurs including a dinosaur directory, fossil specimens, information, pictures, and more. The exhibit also...

This comprehensive page discusses the Asteroid Impact vs. Volcano-Greenhouse dinosaur extinction debate. It was written by paleontologist, professor, and scientist Dr. Dewey McLean.

An overview of the mass extinctions throughout earth history. Each mass extinction has a link to its own page with a list of its possible causes and the species that were most affected.

Are we in the midst of a mass extinction? Is Homo sapiens triggering this mass extinction? Four expert panelists have written responses to the aforementioned questions for this highly informative site.

A list of references to articles about biodiversity patterns of speciation and extinction.

45,000 - 50,000 years ago the megafauna of Australia became extinct. This interview investigates several possible causes such as, continental drift, human impact, and climate change.

This article is about the many mammals that became extinct in the late Pleistocene era. Many causes are considered and there are some great questions at the end for your consideration.

A look at fossil evidence that reveals life and ecological interactions of the extinct fan palm tree.

"The survivals and extinctions at the close of the Cretaceous are such as might be expected to result from intensely hot winds such as would be generated by extra large meteoritic impacts." This article suggests that this theory should...

This theory from the University of Chicago of dinosaur extinction revolves around the concept of plate tectonics, the movement of the continents over a sort of liquid around the planet.

The first meteorite fossil discovered in this period when tests can be run on it, was found at Chicxulub in Northeastern Yucatan, Mexico. Scientists believe it is part of the meteorite which made the dinosaurs extinct.

This dinosaur site, containing eight different sections, includes topics such as: 101 crazy theories about dinosaur extinction, the pattern and timing of extinction, evidence for late cretaceous climatic change, gradual extinction and...

This site provides a virtual tour to the Hooper Virtual Paleontological Museum. There are many virtual exhibits to visit through a series of links, including Mass Extinctions and Human Evolution. Very descriptive and fun tour!
