Students will answer questions about the online Science News article “It’s possible to reach net-zero carbon emissions. Here’s how,” which explores various solutions to decrease greenhouse gas emissions. A version of the article, “The road to net-zero,” appears in the January 28, 2023 issue of Science News.

Students will review, discuss and diagram atmospheric greenhouse gases and their impact on Earth. Then students will analyze a graph to begin thinking about what it will take to achieve net-zero emissions. Learning Outcomes: Reviewing greenhouses gases and their impact on Earth, diagramming human impact, understanding the idea of net-zero emissions.

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

In this quick activity, students will create their own unit of length to measure something in the classroom and use principles of dimensional analysis to convert their measurement to a partner’s unit. Learning Outcomes: Units of measurement, unit conversion.

Students will answer questions about a Science News article that explores new prefixes for the metric system. A version of the article, “The metric system gains new prefixes,” appears in the January 14, 2023 issue of Science News.

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.

The world population has reached 8 billion people, according to the United Nations. In this guide, students will learn about how the human population has grown over time and how it is projected to grow in the future, then analyze a graph of world population data. In a quick activity, students will think about how a growing human population might impact various industries and how changes at the national or international level might help those industries support a larger population.

In this quick activity, students will brainstorm the effects of population growth on industries such as agriculture and medicine, then will work collaboratively to come up with changes at the national or international level that will help those industries support the growing population.

Students will explore a graphic representation of trends in the size of the global human population and analyze the importance and implications of projected data.

Students will answer questions about the Science News article “The world population has now reached 8 billion,” which explores trends in human population growth. A version of the article, “Human population hits a milestone,” appears in the December 17, 2022 & December 31, 2022 issue of Science News.

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.

Large swarms of insects could produce as much electricity as a storm cloud. In this guide, students will explore how insect-induced static electricity might affect the atmosphere, review the concepts of electric charge and electrostatic force, and apply those concepts to their own experiences and the biological phenomenon of insect swarms. In a quick activity, students will create a poem or song about serendipity in science.
