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.

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 multitalented Louis Pasteur was a chemist, biologist, the father of microbiology and the inventor of pasteurization. In this hands-on lab, students will learn about Pasteur’s contributions by conducting an inquiry-based yeast fermentation experiment that explores the concept of pasteurization. In this experiment, students will observe, calculate and graph the volume of carbon dioxide produced by yeast during fermentation at different temperatures and identify the point where the yeast have been killed and pasteurization occurs.

Get your students exploring the scientific method by applying scientific problem-solving to their favorite sport. Learning outcomes: Scientific method.

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.

Students will design and build models inspired by flying seeds with the goal of making the models travel as far as possible. Students will test the models, analyze which ones performed the best and explain why those models performed well using physics principles.

In this guide, students will learn about the origin of organic material found inside a meteorite from Mars and discuss how new evidence can be used to reevaluate scientific claims.

Students will compare two Science News articles and analyze how new evidence has revised an initial claim and the reasoning behind that claim. As a bonus, students can answer chemistry questions about abiotic and biotic reactions.

Students will answer questions about the online Science News article “Organic molecules in an ancient Mars meteorite formed via geology, not alien life,” which describes new research into the origin of organic material found in a space rock. A version of the article, “Meteorite’s organics aren’t signs of life,” appears in the February 12, 2022 issue of Science News.

In this guide, students will explore chemical interactions within wildfire smoke and how urban air pollution can influence the reactions.

Students will answer questions about the online Science News article “Wildfire smoke may ramp up toxic ozone production in cities,” which explores new research into the interactions between wildfire smoke and air pollution in cities. A version of the article, “Wildfires may boost urban ozone levels,” appears in the January 15, 2022 issue of Science News.
