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.
From buildings to machines to household objects — and even in the natural world — the structure of something relates to its function. Sea urchin skeletons, for example, have a recurring geometric design called a Voronoi pattern that also shows up in honeycombs and dragonfly wings. The pattern probably strengthens the skeleton and could inspire the creation of strong, lightweight materials. In this activity, students will explore aspects of structure and function in everyday objects before applying the same concepts to the natural patterns found in sea urchin skeletons. Inspired by the sea urchin, students can use an engineering design process to brainstorm solutions to real-world problems.
Are your students creeped out by spiders? They aren’t alone. In this guide, students will learn about how inaccurate news coverage has promoted common misconceptions about the largely harmless critters. Students can also discuss misinformation, thinking about where they’ve encountered it before, its impacts and ways to correct it.
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 answer questions about the online Science News article “Why do some people succeed when others fail? Outliers provide clues,” which describes how research into communities that defy expectations can reveal ways to help others.
Students will discuss the uses of data visualizations, analyze visualizations from a Science News article, and think about how psychological tools used by elite athletes might benefit their own lives.
