Just when we all thought we had evaporation all figured out, clever experiments shine a new light on old assumptions. A new study points to light having the ability to help sever bonds (a type of intermolecular force) between water molecules to boost evaporation. Learn how these findings support new scientific claims and challenge the old notion that light affects evaporation only indirectly, through heat generation.

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.

Summers are getting hotter. Use this guide to help students explore the science of heat and its effects on the body, and then apply what they learn through diagramming.

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

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 answer questions about the online Science News article “Grainy ice cream is unpleasant. Plant-based nanocrystals might help,” which describes new research into improving the shelf life of ice cream. A version of the article, “Cellulose helps ice cream go down smooth,” appears in the May 7, 2022 & May 21, 2022 issue of Science News.

Students will define rates and their units of measurement for biological and chemical processes before discussing factors that affect rates.

Students will answer questions about the Science News article “Some deep-sea octopuses aren’t the long-haul moms scientists thought they were,” which describes how octopuses laying eggs in warm waters near geothermal springs speed up hatching. A version of the article, “Deep-sea ‘octomoms’ seek the heat,” appears in the April 9, 2022 issue of Science News.

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.

Students will discuss the composition and properties of air and wildfire smoke, and explore how substances in smoke react to ramp up a certain type of air pollution.

Students will answer questions about the online Science News article “New high-speed video reveals the physics of a finger snap,” which details scientists’ exploration of the friction required for finger snapping. A version of the article, “Camera captures physics in a snap,” appears in the December 18, 2021 & January 1, 2022 issue of Science News.
