In this guide, students will answer claim, evidence and reasoning questions about how scientists used the bones of ancient fish to determine during what season an asteroid wiped out nonavian dinosaurs. They will then explore the physical properties of human bones and how bones offer evidence to support scientific claims.
Students will answer claim, evidence and reasoning questions about the online Science News article “The Age of Dinosaurs may have ended in springtime.” The article describes how scientists used fossilized fish to determine what season it was when an asteroid wiped out nonavian dinosaurs. A version of the article, “Dinosaur killer may have hit in spring,” appears in the March 26, 2022 issue of Science News.
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.
These discussion prompts encourage students to apply their knowledge of experimental design.
