Take a seat, “angel hair” pasta. Scientists just fine-spun the world’s thinnest spaghetti. This nano-noodle recipe calls for modern electrospinning technology blended with creative culinary science — and, of course, a handful of pasta dough. Learn how electrospinning works by comparing the technique to the function of an old-fashioned spinning wheel, at the same time answering questions about polymers and connecting chemistry concepts to textile manufacturing.

Love mayonnaise or hate it, physicists just put this contentious condiment to work. Scientists struggle to study the behavior of matter during the process of nuclear fusion. Learn how researchers overcame some of these obstacles: They used a condiment with some surprisingly similar characteristics. It also helped them answer questions about the value of models for illustrating scientific processes.

Take note — there could soon be a new element on the block. By smashing atoms together, scientists have been expanding our periodic table of elements beyond what occurs in nature. Learn how scientists create them while answering questions and discussing how such innovations may help us in the future.

Physicists propose that trees may help detect high-energy subatomic particles called neutrinos. Learn how Earth’s atmosphere alters these incoming high-energy subatomic particles from space. Then, explore how scientists could use this interplay to develop new ways to detect high-energy neutrinos.

Colliding tectonic plates might make your diamond blush. Learn how differences in crystal structure give rise to distinctive physical differences, such as the rare pink diamonds of Western Australia. Answer questions about the value of skepticism in science and discuss how uncovering the history of our planet can give us a treasure-hunting lead.

Summary: Students will review the ideal gas law and use a simulation to explain the assumptions made in a recent study about how climate change is impacting baseball. Learning Outcomes: Exploration of the cause and effect of manipulating conditions of a gas using a simulation, identifying relationships of variables using a mathematical equation and application of theoretical concepts to real-world examples.

Students will answer questions about the online Science News article “Baseball’s home run boom is due, in part, to climate change,” which explores how increases in temperatures boost home run numbers. A version of the article, “Climate change spikes baseball homers,” appears in the May 6, 2023 & May 20, 2023 print issue of Science News.

Many of the things people make — from concrete to bread — undergo physical and chemical changes during production. While making bread, students will learn more about the differences between chemical and physical changes and how the two are related.

The ancient Romans built concrete structures that have stood for thousands of years. In this Guide, students will learn how scientists experimented to make Roman-style concrete — without causing explosions!

Use a real-life example to give students a deeper understanding of physical and chemical changes and properties of substances.

In this quick activity, students will write a scientific question to learn more about a historical artifact. Learning Outcomes: Asking scientific questions

Students will answer questions about the online Science News article “These chemists cracked the code to long-lasting Roman concrete,” which explains the process scientists used to re-create the Romans’ superb building material. A version of the article, “Chemists Crack the Code to Ancient Roman Concrete,” appears in the February 11, 2023 issue of Science News.
