Light up your class with examples of fluorescence, including recently found biofluorescence in many frog species. Learn about the discovery of fluorescing frogs, discuss the potential evolutionary advantages of fluorescence, answer questions about the chemistry behind fluorescence and perform a demonstration of fluorescence from common objects.
How is the U.S. doing in its transition away from coal-fired power plants to renewable energy sources? Analyze state and national data to learn about the transition and one of the major challenges: keeping the grid stable as large power plants shut down.
Staying cool in the summer and keeping warm in the winter may become easier. Learn about a new thermal fabric prototype and its ability to regulate temperature, answer questions about its design and function and discuss potential applications.
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.
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.
Heat waves are becoming more frequent around the globe, and scientists are studying humans’ ability to endure the extra heat. Get students thinking about what it means to handle heat and explore basic thermodynamic concepts through diagramming. Learning Outcomes: Diagramming
In this guide, students will learn about how food scientists are using chemistry to improve the texture of ice cream, discuss the science of ice cream on a molecular level and brainstorm testable scientific questions about favorite frozen desserts.
Students will analyze and write a caption for microscope images of crystals in an ice cream–like solution, discuss how molecules behave as ice cream freezes and thaws, and pose scientific questions about one of their favorite frozen desserts.
