Scientists built hula-hooping robots to answer an old mystery: How does a Hula Hoop stay up? Learn how best to launch and maintain a circulating hoop — and then explore how specific shapes can turn gyrations into a gravity-defying force. You can apply those concepts to then predict the hula-hooping success of other shapes.

Virtual reality (VR) has expanded people's ability to experience visual and auditory sensations in virtual worlds. What about our other senses? Learn how chemical-detection capabilities of the tongue allow us to taste cake as being sweet and lemonade as being sour. Explore how scientists used this understanding to develop taste-mimicking VR technology, all while answering questions about how this tasty research might one day help people.

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.

Strange ghostly blue lights have haunted the little town of Summerville, S.C. for decades. Reports of spectral balls of light floating along a desolate stretch of railroad inspired a ghostly local legend. Learn how legends can inspire real-world science. Then discuss similarities and differences between scientific theory and legend while answering questions about a proposed geologic explanation for this phenomenon.

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.

Scientists just caught a rare glimpse of an exoplanet’s innards. Learn how scientists use wavelength data from the James Webb Space Telescope to figure out what exoplanets might be made of. Answer questions about the value of personification as a literary device, all the while discussing how knowledge gleaned from one discovery can help scientists answer new and lingering questions.

ooking for exciting and important applications of the phases of matter? Have students answer a set of questions relating changes in pressure to changes in states of matter. Learn about how hydrothermal explosions occur and the risk for these at Yellowstone National Park, all while discussing how geologists use core data to piece together geological history.

Take a seat, “angel hair” pasta. Scientists just fine-spun the world’s thinnest spaghetti. This nano-noodle recipe calls for modern electrospinning technology blended with creative culinary science — and, of course, a handful of pasta dough. Learn how electrospinning works by comparing the technique to the function of an old-fashioned spinning wheel, at the same time answering questions about polymers and connecting chemistry concepts to textile manufacturing.

Ocean explorers just uncovered a treasure trove. A newly discovered undersea mountain may be home to 20 new species. Explore these life forms while answering questions about the value of such discoveries in a time of rapid climate change.

Science fiction sometimes inspires real-world innovation. Future spacesuits may filter urine into drinkable water, allowing astronauts to wear those suits for longer tasks. Learn how researchers propose to make fantasy a reality while answering questions about the filtration techniques and how spacesuits are needed to handle the constraints of space.

Learn how scientists use vampire bats' unusual locomotion to investigate mysteries of their blood-based metabolism. Then, answer questions about this study’s experimental design and discuss how chemical analysis data can support conclusions and answer scientific questions.

Wildlife smugglers beware: A new border-patrol agent may scurry into nearby airports. Learn how African giant pouched rats in tiny red vests are being trained to sniff out elephant ivory and other illegal goods from at-risk species. Then answer questions about the ethics of the experimental design of animal studies and the value of biodiversity.
