Students will learn how CRISPR gene-editing technology works and discuss its applications and its importance to research. Learning Outcomes: Learning about CRISPR and why it is an important technology

Students will answer questions about the online Science News article “Prairie voles can find partners just fine without the ‘love hormone’ oxytocin,” which explores how scientists upended a common understanding of the hormone by using CRISPR technology. A version of the article “Voles don’t need oxytocin to bond” appears in the February 25, 2023 issue of Science News.

Have you ever wondered how the people who get to fly in space are chosen? The path to becoming an astronaut has changed a lot over the years. In this activity, students will learn about the space travelers of the past and present — and consider a future where the diversity of astronauts better reflects the diversity of all of humankind. Students will use their creative writing skills to imagine this future.

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.

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.

In this quick activity, students will write a scientific question to learn more about a historical artifact. Learning Outcomes: Asking scientific questions

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.

Lakes can vary in color based on levels of sediment, organic matter and algae. Sometimes though, a lake will stand out – not matching the other lakes in an area. Look for these anomalies by participating in a virtual lake scavenger hunt, and help figure out why these lakes don’t fit in! In this activity, students will learn how climate change influences lake color and will investigate lakes with irregular colors that have been impacted by natural or human-made forces.

Human activities pump a lot of greenhouse gases into the atmosphere, and those emissions are driving climate change. In this guide, students will review greenhouse gases and their sources and learn about ways to reduce emissions.

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.
