Methane in the Atmosphere
To tackle our warming climate, we’ll need to rein in emissions of carbon dioxide, but there’s another greenhouse gas at play: methane. Decreasing methane concentrations may be the best bet for stopping rising temperatures in the short term.
Convection Connections
For astronomers, watching convective cells of gas move on the surface of a distant star was kind of like looking at a lava lamp. Begin a unit on energy transfer by having students discuss lava lamps and the process of convection at work in them. Then have students read about the first observation of convection on a distant star and its potential scientific importance. Finally, students will brainstorm and diagram other examples of devices or natural processes that involve convection.
Investigating phenomena with SEPs
To investigate why some meteors create persistent trails, scientists filmed the New Mexico sky for two years, recording streaks of light. Use shooting stars as an example phenomenon to generate student interest, wonder and questions. Then, have students explore how this phenomenon was studied using Science and Engineering Practices, while evaluating the study’s design, limitations and possibilities for future research. Finally, have students search for another phenomenon that interests them and begin asking questions about it.
All eyes on the sun
On April 8, 2024, approximately 32 million people may have the opportunity to see a total eclipse of the sun. Astronomers predict this eclipse will put on quite a show — one of the most vivid in recent history. Learn how different factors of this solar eclipse will make it especially rare for both scientists and casual observers.
Scaling the world’s largest telescope
The Giant Magellan Telescope could reveal signs of life on faraway planets — mainly because of the telescope’s massive mirrors. But just how big are they? Use this article to investigate the benefits of using scale and relative values in writing. Then solve a related word problem and devise your own useful examples of scale.
Prepare Your Community for the Eclipse
This activity will help students learn more about eclipses and how to communicate scientific information through the creation of a video about the upcoming total eclipse on April 8, 2024. Students will practice summarizing information from a variety of Science News Media Group articles and will use their writing skills to create an informative script for their video. For those in the solar eclipse’s path, the video will also discuss where to watch the eclipse and how to get involved in community education projects.
Why doesn’t this dwarf planet follow the rules about rings?
Students will answer questions about the online Science News article “The Kuiper Belt’s dwarf planet Quaoar hosts an impossible ring,” which describes a recent astronomical discovery that is completely counter to what scientists expected to see. A version of the article, “This dwarf planet hosts an odd ring,” appears in the March 11, 2023 issue of Science News.
Defining and defying Roche limits
Students will review force diagrams and gravitational force and discuss planetary ring and moon formation using the concept of the Roche limit.
Learning Outcomes: Applying gravitational forces and interactions in space to understand ring and moon formation.
What’s the deal with DART?
In this quick activity, students will create a TikTok video about the outcome of a NASA mission to knock an asteroid off course.
NASA’s DART Mission Is a Success
Did you hear about the spacecraft that crashed into an asteroid — on purpose?! In this guide, students will learn about NASA’s DART mission and discuss the core physics principles behind it.
Bumping asteroids off course
Students will answer questions about a NASA mission to smash a spacecraft into an asteroid after reading a Science News article and watching a Science News TikTok video about the mission. A version of the article, “NASA’s DART mission is a success,” appears in the November 5, 2022 issue of Science News.
Postcards From a New Space Telescope
Have you heard about the James Webb Space Telescope’s stunning first images of deep space? Use this guide to help students explore the science behind pictures of exploding stars, dancing galaxies, cosmic cliffs and more, and discuss how images can be thought of as data.
