This video segment adapted from First Light explains why the highest peak in the Pacific, Mauna Kea, is an ideal site for astronomical observations. Featured are new telescope technologies that allow astronomers to explore the universe in more detail. [5:39]

NASA scientist Sten Odenwald calls this his "web site for the astronomically disadvantaged." Do you have lots of questions about space that you can't seem to get answers to? Would you like to learn about a career in astronomy, Big Bang cosmology, and many other in astronomy? If so, this is the place to get the answers.

This 10-minute video lesson looks at the formation of the Earth which is a the byproduct of a local supernova. [Cosmology and Astronomy playlist: Lesson 38 of 85]

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

This visualization adapted from NASA maps progressive global changes onto a rotating globe. Earth's atmosphere, hydrosphere, geosphere, and biosphere are shown to be dynamic and interconnected.

This video segment adapted from NOVA shows how Galileo used his telescope to carefully observe and study sunspots.

Learn how New York City's drinking water travels from watersheds in upstate New York in this segment from the WPSU documentary Liquid Assets. [2:45]

Part of the NASA website, this is a reprint of an article in the Journal of the Royal Astronomical Society of Canada about Edwin Hubble's life and accomplishments, stressing his role in the development of modern astronomy.

NASA sponsored site dealing with several topics in Astronomy and Astrophysics. The site provides links to various topics.

NASA has discovered water in space. This interactive resource allows you to examine the different planets and moons in our solar system to find out where their water is located.

This lesson teaches students about the characteristics of planets, comets, asteroids, and trans-Neptunian objects. After learning about these different things, students then are to debate about a new object that is found in space.

SciGirls videos feature real girls putting science and engineering to work to answer real-life questions and make discoveries in the world around them. This collection explores oceans, sky, and earth environments.

Computer science is a subject that is becoming more important to teach our students to prepare them for their future. Coding and having a basic understanding of different coding languages will be key for our students to feel truly ready for college or their career. Introducing students to these concepts can be a daunting task. This content package is created to try and alleviate some of those concerns. Within this content package for students in grades 5-8, educators will find lesson plans and activities that will help teach introductory computer science concepts. Educators will also find eBooks and digital texts to share with students, as well as videos to help guide students’ understanding of computer science.

Scientists discuss a newly discovered moon orbiting Neptune, which is just 12 miles across.

Many generations have felt they've reached the pinnacle of technological advancement. Yet, if you look back 100 years, the technologies we take for granted today would seem like impossible magic. So- will there be a point where we reach an actual limit of technological progress? And if so, are we anywhere near that limit now? Clement Vidal consults Kardashev's scale to find out. [4:46]

Most 12-year-olds love playing video games- but Thomas Suarez taught himself how to create them. After developing iPhone apps like "Bustin Jeiber," a whack-a-mole game, he is now using his skills to help other kids become developers. [4:33]

Brute computing force alone can't solve the world's problems. Data mining innovator Shyam Sankar explains why solving big problems is not a question of finding the right algorithm, but rather the right symbiotic relationship between computation and human creativity. [12:13]

This site contains information about Brahe's contributions to astronomy, and also discusses his planetary model.

This site provides extensive information on the controversial theory that there are millions of small comets which continually burn up yearly in the earth's atmosphere.

The videos in this collection will give an understanding that a watershed includes a healthy forest, undergrowth, creeks, streams and rivers that all drain toward a large body of water, in this case, the Salt and Verde Rivers. These components work together to store and filter water as it moves through the watershed, flows into the reservoirs downstream, and eventually comes out of your tap. It includes 6 videos for grades 3-12.

Windows to the Universe has developed an interactive resource about the earth, space, biological and physical sciences. Content includes information on our planet, the solar system, the universe, myths associated with space, space missions, ecology, genetics, and much more. Content can be changed from beginner to intermediate to advanced.
