This guide, based on the Science News article “Here come the (bigger) mammals,” asks students to analyze a graph about a recent fossil find, discuss how organisms evolve as ecosystems change and research important fossil sites across the world.
Students will explore the immediate and long-term effects of specific environmental disturbances, including how energy enters or leaves an ecosystem, how the biotic and abiotic characteristics of the ecosystem change and how organisms evolve under the new conditions.
In this activity, students will research important fossil sites across the world and synthesize what they find into a story to present to the class.
