Meet Louis von Ahn, computer scientist and professor at Carnegie Mellon who is already at the top of his field at age 30! In this video for grades 6-12 from NOVA scienceNOW, students can learn about one of his most successful ideas—CAPTCHA—a test that humans can pass but computers cannot, which has been used to improve the security of Internet sites. They’ll also discover how he comes up with his innovative ideas, and how CAPTCHAs have been reinvented to help digitize old books. Resources include background essay, discussion questions and National Standards/Benchmarks for Science Literacy.

Snow is likely to become a part of our landscape before long. This week PBS LearningMedia features resources to dig into the science beneath the ice and snow to better appreciate the wonders of the winter season. You and students can explore hibernation, snowflake physics, and the ecosystems of Earth’s polar regions with:
Joy Learno: snowman (PreK-1) : Talk show host, Joy Learno, interviews a snowman who likes to crack jokes about snow and ice . Then the snowman starts to melt. This video segment from Between the Lions provides a resource for language and vocabulary development.
Why Do Snowflakes Come in So Many Shapes and Sizes? (Grades 6-8): In this lesson students build an apparatus that creates conditions similar to a winter cloud and produce their own snow crystals indoors. They learn about the molecular forces that shape ice crystals, and gain a deeper understanding of the states of matter.
Inspiration from Hibernation (Grades 6-12): From NOVA scienceNOW’s “Can We Live Forever?” this video teaches how research on animal hibernation may lead to the successful development of drug therapies for humans.
Life on the Ice (Grades 9-13+): In this video from the National Science Foundation and the Desert Research Institute, learn about WAIS Divide, an ice core project on the West Antarctic Ice Sheet and hear from the people involved in the hard work and light-hearted fun that typifies day-to-day life in the WAIS Divide camp.
WGBY will air “At the Edge of Space” on Wednesday, November 20, at 8:00pm. This NOVA episode takes viewers on a spectacular exploration of the earth-space boundary zone, home to some of nature’s most puzzling and alluring phenomena: the shimmering aurora, streaking meteors, and fleeting flashes that shoot upwards from thunderclouds, known as sprites that flicker into existence for a mere split-second — 40 times faster than an eye blink.
NOVA rides with scientists in a high-flying weather observation plane as they hunt for sprites and finally succeed in snaring them in 3D video, gaining vital clues to unravel their mystery. NOVA also combines advanced video technology with stunning sequences shot from the International Space Station. Preview.
NOVA’s Beta site offers many related links, including stunning images galleries. And at PBS LearningMedia you’ll find nearly 2000 digital resources for space — videos, lesson plans, interactives and more — for grades 6-12 (and younger). With easy to use search filters for grade, specific content and standards, you can explore, save and file favorites for teaching and learning about this infinite subject.
In recognition of Earth Science Week (October 13-19), invite your students to investigate the relationship between the land, ocean, and the atmosphere. Use the special collection highlighted on the homepage of PBS LearningMediato to illustrate key concepts with student-friendly visualizations and vivid imagery.
Here are two resources aligned to National Standards that you’ll find among many for Earth Science Week:
Lightening Produces Nitrates (Grades 6-12): In this video excerpt from NOVA: “Earth From Space,” learn about the global impact of lightning and how it produces an essential nutrient for living things. Satellite images show the distribution of electrical storms on Earth and the frequency of lightning strikes. Visualizations and narration describe the formation of lightning and its role in the production of nitrate, a vital nutrient for life. This video also explains how rain transports nitrate to the ground, where it is absorbed by plants and becomes a part of the food chain.
Life on Fire: Measurement (Grades 6-12): Understand the current technological revolution driven by the extensive use of telemetry to monitor volcanoes and the conflict between the scientists risking their lives to understand and predict the next eruption set against the pragmatism of people who live and work in the shadow of moody volcanoes. See how one scientist measures the seismic activity of a volcano in Papua, New Guinea.
We hope you’re already familiar with NOVA and NOVA educator resources. Now this longest running television science program is excited to announce the launch of the Cloud Lab at http://www.pbs.org/nova/labs/lab/cloud/, the third Lab in a growing collection of research offerings on the NOVA Labs site. In this NASA-funded site users can learn how to track the development of storms and better predict their impacts by conducting their own investigations about developing storms.
The Cloud Lab also includes a cloud gallery with 260 beautiful images of a range of 10 cloud types, from cirrus to cumulus to altostratus. Users are challenged to analyze the cloud images and classify each cloud type they observe in the image — collecting favorites along the way.
If you want to learn more about the Cloud Lab, you’re invited to join NOVA for an online presentation about this free digital resource this fall — https://www.surveymonkey.com/s/cloudlab.
Here is a four-part series that take an incredible Australian journey to learn about some of the most iconic animals found in this breathtaking country. The series comprise: Survivors of the Firestorm; Outback Pelicans; Cracking the Koala Code and Kangaroo Mob. DVD format. Borrow this video, Australia: Animals Down Under (I.D. 2375) for a month by clicking here.
This Wednesday, May 29, at 10:00 pm WGBY will broadcast NOVA’s Oklahoma’s Killer Tornadoes. On May 20, 2013, a ferocious EF5 tornado over a mile wide tore through Moore, Oklahoma, inflicting 24 deaths and obliterating entire neighborhoods. It was the third time an exceptionally violent tornado had struck the city in 14 years. Yet predicting when and where these killer storms will hit still poses a huge challenge. In this NOVA special, you’ll meet scientists in the front ranks of the battle to understand these extreme weather events. You also meet storm survivors whose lives have been upended and learn how we can protect ourselves and our communities for the uncertain future.
At the NOVA Beta site, you can watch a preview and find related links such as Hunt for the Supertwister, Rate Tornado Damage, Tornado Country, and Killer Tornado of 1928. NOVA Teacher resources include the videos How Do Tornadoes Form? to learn how scientists use computer simulations to explore the question of how supercell thunderstorms produce tornadoes and Chasing Tornadoes to follow scientists on their hunt for tornadoes using Doppler radars to gather data and solve how tornadoes are formed.
From Emily Dickinson’s poem “Narrow fellow in the grass” to the story of Adam and Eve, snakes are likely to get our attention as they will this Wednesday, May 8, at 9:00pm when WGBY airs NOVA’s Venom: Nature’s Killer.
Over the millennia, thousands of creatures have developed that most sophisticated of biological and chemical weapons: venom. These complex chemicals can scramble our brain signals, paralyze muscles, puncture blood cells, even begin digesting us from within. But nature’s most potent toxins might also contain the keys to a new generation of advanced drugs to help doctors treat serious illnesses such as heart attacks, cancer and diabetes.
Follow NOVA crews as they join scientists on a dangerous quest to track down and capture the world’s most venomous animals—to find out both how they can kill us, and how they can save us. Watch a preview.
Epic in scope, intimate in nature, this 4-part NOVA miniseries reveals the untold story of the Land Down Under. With high-energy host and geologist Richard Smith, meet titanic dinosaurs and giant kangaroos, sea monsters and prehistoric crustaceans, disappearing mountains and deadly asteroids. Though it started last week, you still have a chance to catch up. The series continues on Wednesday nights through May 1 from 9-10pm on WGBY. Learn more.
