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.

Students will research how climate change affects a nonhuman species, propose science-based solutions that might lessen the impact of climate change on the species and create an infographic to share with the class.

In this guide, students will learn how scientists estimated the food intake of certain whale species and discuss nutrient cycling and conservation of matter within ecosystems.

Students will discuss nutrient cycling and conservation of matter, and how these concepts can be observed in an ecosystem.

Students will answer questions about the online Science News article “Baleen whales eat (and poop) a lot more than we realized,” which details scientists’ efforts to accurately estimate how much certain whale species eat and what that means for ecosystems. A version of the article, “Whales eat more than we thought,” appears in the December 4, 2021 issue of Science News.

Students will discuss the physics of drag using real-world examples.

Students will answer questions about the online Science News article “Here’s the physics of why ducklings swim in a row behind their mother,” which details how baby ducks save energy by surfing their mom’s waves. A version of the article, “Why baby ducks swim in a line,” appears in the November 20, 2021 issue of Science News.

In this guide, students will learn about how mitochondria help the ocean’s smallest mammal generate body heat. Then, students will discuss cell structure and energy production, diagram how mitochondria function and brainstorm a research question.

Students will answer basic questions about cell structure and energy production, draw diagrams to visualize how mitochondria in sea otters may function differently than in other marine mammals and brainstorm a research question for further investigation.

Students will answer questions about the online Science News article “Sea otters stay warm thanks to leaky mitochondria in their muscles,” which explores scientists’ efforts to figure out how the ocean’s smallest mammal maintains an extreme metabolism. A version of the story, “How muscles keep otters warm,” appears in the August 14, 2021 issue of Science News.

Students will learn how science journalists develop stories from scientific studies by analyzing a Science News article and the study on which it is based. Then, students will use a scientific study provided by the teacher to write their own news article.
