Solving a French Revolution mystery with chemistry
Students will answer questions about the online Science News article “Ink analysis reveals Marie Antoinette’s letters’ hidden words and who censored them,” which details how scientists used chemistry to unravel a mystery from the French Revolution. A version of the article, “Marie Antoinette’s letters are uncensored by X-rays,” appears in the November 6, 2021 issue of Science News.
- Chemistry
Revealing secrets with spectroscopy
Students will discuss how spectroscopy relates to atomic structure, how the technology can help solve historical mysteries and the limitations and ethics of such work.
- Tech
Reimagining plastics recycling
Students will evaluate experimental methods for recycling plastics, gather data about the types of plastics they use at home, research plastics recycling in their community and write a letter to local officials that advocates for improving plastics recycling.
- Particle Physics
Dig into atomic models
Students will research how knowledge of the atom has changed over time, visually represent a historic atomic model and present that model to the class. Students can also explore the standard model of particle physics and discuss ways it could be depicted.

How Muscle Cells Keep Otters Warm
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.
- Animals
Mighty mitochondria
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.
- Animals
Sea otters’ cellular surprise
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.

Physics Helps Alien Rain Stay In Shape
In this guide, students will learn how the laws of physics shape rain on other planets and explore how molecules interact within alien raindrops.
- Physics
Sizing up alien rain
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.
- Chemistry
Modeling molecules in alien rain
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.
- Chemistry
Bonds in limbo
Students will answer questions about the online Science News article “This weird chemical bond acts like a mash-up of hydrogen and covalent bonds,” which explores new research that suggests chemical bonds exist on a continuum. A version of the story, “Chemical bond acts like a mash-up,” can be found in the January 30, 2021 issue of Science News.
