Gardens have many functions ranging from vegetable and fruit production to flood mitigation and erosion control. Gardens also can be a haven for pollinators and a repository for native plants. Over the course of a year, students will design a garden for their school or a community organization using scientific concepts they learn in class.

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.

Climate extremes are impacting human health and inspiring new technology. This guide provides lesson plans paired to recent news articles covering a new thermal fabric prototype and its ability to regulate temperature and how wildfire smoke impacts the air quality index and human health.

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.

In this quick activity, students will discuss confounding factors in their own lives and in scientific research to determine why it is important to identify and control for those factors. Learning Outcomes: Reviewing confounding factors and learning why it is important to identify them in science.

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.

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.

In this guide, students will learn about new measurement prefixes, work with those prefixes in metric conversions and create their own units of measure.

Students will review prefixes and their meanings, learn about the metric system’s newest prefixes and apply the definitions in metric conversions. Learning Outcomes: Proportion and scale, measurement and dimensional analysis, a deeper understanding of the metric prefixes.
