Even isolated colonies of Pacific albatrosses can eat a stomach-full of plastic trash.
Lesson Plan, Science Bulletins
As the suburbs flourish, wood turtles struggle to survive.
This exercise should familiarize the students with the graphic organizers.
Classroom Activity, Educator Guide
This discussion explores the difference between natural and human-made boundaries and their effect on isolated populations.
Introduce students to the bighorn sheep Science Bulletin video, the scientist who conducted the research, Clinton Epps, and the effect of highways on Las Vegas and the sheep habitat.
Discuss how scientists define populations, and the consequences of inbreeding in animal populations like the Florida panther and purebred dogs and horses, and in human populations like the Amish and the Habsburg royal family.
Students use maps and rulers to analyze the genetic data that Dr. Epps collected from the bighorn sheep.
Classroom Activity, Lesson Plan
Students draw genetic data onto maps and make conclusions about which sheep populations are affected by highways.
Use Science Bulletins videos to explore other examples of disrupted habitats and populations. See how daily life affects wood turtles, seabirds, monarch butterflies, the Gulf of Mexico, Florida panthers, and badgers.
Re-create the 130-million-year-old forest in what is now China to understand why this fossil site is of such vast scientific importance.
