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!
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.
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.
