In this activity, students conduct an energy audit to determine how much carbon dioxide their family is releasing into the atmosphere and then make recommendations for minimizing their family's carbon footprint.

This PBS video shows how Klaus Lackner, a geophysicist at Columbia University, is trying to tackle the problem of rising atmospheric CO2 levels by using an idea inspired by his daughter's 8th-grade science fair project. The video examines the idea of pulling CO2 out of the atmosphere via a passive chemical process.

In this activity, student teams research and develop a proposal to decrease the carbon footprint of their city's/town's public transportation system and then prepare a report that explains why their transportation plan is the best for their community.

This video segment examines ethanol, a cleaner-burning fuel alternative to gasoline, and the efforts to produce it more efficiently.

This video from a 2005 NOVA program features scientists who study the Jakobshavn Isbrae glacier in western Greenland. The glacier is shrinking and moving faster due to increased melting in recent years. The video includes footage of scientists in the field explaining methods and animation of ice sheet dynamics leading to faster glacier movement.

This animated slideshow introduces biodiesel as a fuel alternative. With concern about the use of petroleum-based fuels at an all-time high, biodiesel is experiencing a popularity surge. And algaeâotherwise known to some as pond scumâ are grabbing headlines as the next potential biodiesel superstar. But how and why do algae make oil? And why do they make so much of it? In this audio slide show, U.C. Berkeley's Kris Niyogi describes the process and its potential.

This 15-panel interactive from NOVA Online describes some of the factors (such as Earth's rotation and the sun's uneven heating of Earth's surface) contributing to the formation of the high-speed eastward flows of the jet streams, found near the top of the troposphere. These jet streams play a major role in guiding weather systems.

This video segment demonstrates carbon dioxide's role in the greenhouse effect and explains how increasing concentrations of C02 in the atmosphere may be contributing to global warming. Video includes an unusual demonstration of C02's heat-absorbing properties, using infrared film, a researcher's face, and a stream of C02 between them.

Learn how scientists have pieced together a continuous 800,000-year record of atmospheric carbon dioxide levels and ocean temperatures in these videos from NOVA: Decoding the Weather Machine. Use this resource to review the difference between inference and observation and to consider the relationships between carbon dioxide, Earth's temperature, and climate change.

"Students explore how to keep their digital lives safe, spot cyber scams, and learn the basics of coding in this media-rich lesson plan from NOVA Labs. The lesson begins with students watching the Cybersecurity 101 video and discussing the online safety measures that they currently take. Next, students makes predictions about online safety best practices, complete the Level 1 challenges of the NOVA Cybersecurity Lab, and compare the best practices from the game with their predictions. Students reconvene for direct instruction on the best practices and key computer science terms and then finish the Cybersecurity Lab game. Finally, students complete the video quizzes with short-response discussion questions and can work on the Cybersecurity stories as homework reading assignments."

In NOVA’s Exoplanet Lab, students will play the role of Moon-based “NOVAnauts” who are on a series of missions as part of a “Galactic Resettlement Team” to rehome several displaced alien life-forms and master the same techniques scientists use to find and characterize exoplanets. Students will first engage in training modules to learn about the transit and radial velocity methods for exoplanet detection. Then they will model using simulated transit and radial velocity data to identify potential exoplanets and determine various planet properties including volume, orbital period, and mass. They will also model using transit spectroscopy to determine the composition of an exoplanet’s atmosphere. Finally, by piecing together all the evidence they have gathered, students will predict how hospitable an exoplanet might be for various aliens looking for a new home planet by matching the characteristics needed by the alien species with the conditions on the exoplanet.

In 1950, Percy Julian was one of the few African Americans with a Ph.D. He was Chicago's man of the year and a groundbreaking scientist. But it wasn't an easy road. Denied teaching positions and the target of death threats, Julian struggled to get ahead in a racially hostile world. Learn more about Percy Julian's contributions to science and civil rights. These resources, adapted from NOVA: Forgotten Genius, explore how Julian revolutionized chemistry with the first synthesis of a chemical compound, as well as the challenges he overcame as an African American facing legalized segregation.

Using a combination of clickable 360 degree landscapes, 2D and 3D videos, animations, interviews with scientists, and mini-games, the Polar Lab takes players onto the glacier ice and into the lab in search of evidence to answer big questions about Earth's climateâpast, present, and future. They search for plant and animal fossils that can reveal what this Arctic and Antarctic environment was like 50 million years ago. Students examine two kinds of clues that act as time capsules for exploring the past: mud cores and ice cores. Finally, students examine the rapid retreat of the massive glaciers and sea ice to better understand how changing ice conditions affect animals.

This activity features video segments from a 2007 PBS program on solar energy. Students follow a seven-step invention process to design, build, and test a solar cooker that will pasteurize water. In addition, they are asked to describe how transmission, absorption, and reflection are used in a solar cooker to heat water and to evaluate what variables contribute to a successful cooker.

This video segment, adapted from NOVA scienceNOW, addresses how new technology can help monitor and modernize the infrastructure of the U.S. power grid, which is ill-equipped to handle our increasing demand for electricity. Video provides a great overview of how electricity is generated and how the grid works.

In this video segment from NOVA's Saved By the Sun hour-long video, students learn about photovoltaics and see how two families are using solar technologies in their homes. The video introduces the ideas of state incentives and net metering benefits.

This video profiles glaciologist Lonnie Thompson and his research into tropical mountain glaciers as a way to understand climate history. Beginning in the 1970s, Thompson recognized that tropical ice cores contain information relating to tropical climate phenomena, including El NiÃo events and monsoons. These phenomena are not archived in ice from polar regions. Thompson explains that his archive of ice cores is full of clues that, taken together with records collected from around the world, can help scientists create a timeline that tells Earth's climate story.
