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.

Vibration check

Most of us drive across bridges every day and never question their structural integrity. We trust that the bridge will stand. In this activity, students will study a famous bridge collapse and consider how it could have been prevented. They also will learn how engineers are testing whether crowdsourced cell phone data could be used to determine when bridges need repairs. Using simulated data of bridge vibration frequencies, students will identify whether an imaginary bridge might be unstable. Students have the option of creating model bridges and testing their structural integrity.

The Metric System Has Gained New Prefixes

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

Measuring up with metric prefixes 

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.

Form fits function in extreme environments

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.

Insect Swarms Might Electrify the Sky

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.

Sticking to static electricity with Coulomb’s law

Students will use their experiences of static electricity to learn about electric charge and electrostatic force, then apply the concepts to a biological phenomenon. Learning Outcomes: Reinforcement of Coulomb’s Law with interdisciplinary examples.

Insect swarms get charged up

Students will read and answer questions about the online Science News article “Insect swarms might generate as much electric charge as storm clouds,” which explores how insect-induced static electricity might affect the atmosphere. A version of the article, “Insect swarms might electrify the sky” appears in the December 3, 2022 issue of Science News.

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.

May the force move you

NASA’s DART mission knocked an asteroid off course. Use the mission to teach core physics principles — including force and Newton’s laws of motion. Learning outcomes: Application of forces and Newton’s laws of motion.

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.

Why Spiraling Footballs Sometimes Miss the Mark

Engage your students in science using sports! In this guide, students can explore the physics of football throws and apply the scientific method to a sport of their choice.
