Applying the ideal gas law
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.
How heat and home runs are connected
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.
Building bread reveals physical and chemical changes
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.
Chemists Crack the Code to Ancient Roman Concrete
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!
Concrete physical and chemical changes
Use a real-life example to give students a deeper understanding of physical and chemical changes and properties of substances.
Write a scientific question based in history
In this quick activity, students will write a scientific question to learn more about a historical artifact. Learning Outcomes: Asking scientific questions
Mix concrete like a Roman
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.
Form fits function in extreme environments
From buildings to machines to household objects — and even in the natural world — the structure of something relates to its function. Sea urchin skeletons, for example, have a recurring geometric design called a Voronoi pattern that also shows up in honeycombs and dragonfly wings. The pattern probably strengthens the skeleton and could inspire the creation of strong, lightweight materials. In this activity, students will explore aspects of structure and function in everyday objects before applying the same concepts to the natural patterns found in sea urchin skeletons. Inspired by the sea urchin, students can use an engineering design process to brainstorm solutions to real-world problems.
