All the listed lessons are designed for 45-minute middle or high school biology or environmental science classes. Ecology Disrupted, the final lesson listed is designed for 90-minute sessions.
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.
Lesson Plan, Classroom Activity
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.
