Students will use the clues provided and the Science News Century of Science website to explore how science advances. After making connections across scientific subtopics, student groups will research and present highlights of discoveries from an assigned decade.

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.

Students will answer questions about the online Science News article “Organic molecules in an ancient Mars meteorite formed via geology, not alien life,” which describes new research into the origin of organic material found in a space rock. A version of the article, “Meteorite’s organics aren’t signs of life,” appears in the February 12, 2022 issue of Science News.

In this guide, students will learn about NASA’s James Webb Space Telescope and discuss how scientific advances have shaped the telescope’s mission.

Students will discuss the mission of the James Webb Space Telescope and explore how scientific discoveries over the last few decades have shaped the telescope’s to-do list.

Students will answer questions about the online Science News article “When James Webb launches, it will have a bigger to-do list than 1980s researchers suspected,” which details the long journey of NASA’s James Webb Space Telescope to make it into space to explore other galaxies. A version of the story, “The origami satellite,” appears in the October 9, 2021 & October 23, 2021 issue of Science News.

In this guide, students will learn how the laws of physics shape rain on other planets and explore how molecules interact within alien raindrops.

Students will answer questions about the online Science News article “How the laws of physics constrain the size of alien raindrops,” which explores a new model for rain on planets across the Milky Way. A version of the story, “Physics helps alien rain stay in shape,” appears in the May 8, 2021 & May 22, 2021 issue of Science News.

Students will compare and contrast rain on Earth with rain on other planets and practice drawing molecular structures of various rain substances to examine the substances' physical and chemical properties. Students will use that information, along with the planetary conditions needed to form rain, to create a short weather forecast for one planet.

In this guide, students will learn about the development of the theory of plate tectonics and discuss how scientific theories are formed.

Students will answer questions about the online Science News article “How the Earth-shaking theory of plate tectonics was born,” which explores how scientists formed the theory of plate tectonics. A version of the story, “Shaking up Earth,” can be found in the January 16, 2021 issue of Science News.
