Students will answer questions about the Science News article “Some deep-sea octopuses aren’t the long-haul moms scientists thought they were,” which describes how octopuses laying eggs in warm waters near geothermal springs speed up hatching. A version of the article, “Deep-sea ‘octomoms’ seek the heat,” appears in the April 9, 2022 issue of Science News.

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 discuss the physical properties of human bones and how bones can offer evidence to support scientific claims. Then students can search Science News for examples of how bones have been used as evidence.

In this guide, students will learn about scientists’ efforts to estimate how many tree species Earth has, analyze a related data visualization and discuss the implications the research has for conservation.

Students will look at data from a primary research article to explore how tree biodiversity differs across continents and biomes.

Students will answer questions about the online Science News article “Earth may have 9,200 more tree species than previously thought,” which describes researchers’ efforts to estimate the number of tree species on Earth. A version of the article, “Earth may be hiding thousands of tree species,” appears in the March 12, 2022 issue of Science News

In this guide, students will learn about outliers and why some social scientists study them in an effort to improve people’s lives.

Students will answer questions about the online Science News article “Why do some people succeed when others fail? Outliers provide clues,” which describes how research into communities that defy expectations can reveal ways to help others.

Students will define what an outlier is and discuss why outliers occur, how to identify them and how they can be useful for science and society.

In this guide, students will learn about the origin of organic material found inside a meteorite from Mars and discuss how new evidence can be used to reevaluate scientific claims.

Students will compare two Science News articles and analyze how new evidence has revised an initial claim and the reasoning behind that claim. As a bonus, students can answer chemistry questions about abiotic and biotic reactions.
