An eyelash of elegant design

Raindrops might fall on your head, but thanks to your eyelashes, they rarely drip into your eyes. Learn how the simple, elegant design of our eyelashes flicks away water. Answer questions about diverse functions of body hair, all while discussing the value of analogies as a literary device used to improve understanding of unfamiliar concepts.

Where force fields collide

Scientists have long suspected that a mysterious third force underlies the unique life-sustaining conditions of our planet but lacked the technology to measure it. Until now, that is. Learn how the interplay between different planet-wide energy forces gives rise to Earth’s cozy atmosphere. Then, explore how scientists use modern technology to study a newly discovered electrical field and fit this knowledge into their global understanding of how our planet supports life.

Egyptian hydraulics: Does this idea hold water?

How did the ancient Egyptians build the pyramids? It's an age-old mystery. A new study points to hydraulic engineering. But does this idea really hold water? Some experts in the field argue against new evidence being provided to support such claims. Learn how researchers use evidence to support claims while discussing the value of healthy skepticism in science.

Green light means “go”

Just when we all thought we had evaporation all figured out, clever experiments shine a new light on old assumptions. A new study points to light having the ability to help sever bonds (a type of intermolecular force) between water molecules to boost evaporation. Learn how these findings support new scientific claims and challenge the old notion that light affects evaporation only indirectly, through heat generation.

A sweaty plant adaptation

Sweating has a surprising purpose for one desert plant. Students will learn about a chemical adaptation that allows the plant to collect moisture in an arid environment. They’ll answer questions about using videos to collect data and then draw molecular diagrams that illustrate the plant’s adaptation.

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.

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.

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.

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.
