In this video segment adapted from NOVA, a geologist digs a trench along the San Andreas Fault to reveal three thousand years of earthquake history. Information from the layers of sediment may help geologists to predict earthquakes.

This video segment adapted from NOVA uses historical illustrations, photographs, and animations to explain how seismographs work, the difference between P and S waves, and the Richter scale.

This issue of the free online magazine, Beyond Penguins and Polar Bears, explores glaciers, wind, water, and volcanoes and their role in shaping the landscape of the polar regions.

This article assembles free resources from the Earth's Changing Surface issue of the Beyond Penguins and Polar Bears cyberzine into a unit outline based on the 5E learning cycle framework. Outlines are provided for Grades K-2 and 3-5.

Learn about the different features of snow and ice in Antarctica using satellite imagery in this video segment adapted from NASA.

In this activity, students will compare their lives on Earth with a virtual experience on Mars. They will begin by using their five senses (sight, smell, hearing, touch, and taste) to illustrate and describe various aspects of their lives on Earth. After similarly describing their virtual time on Mars, they will consider the biggest similarities and differences between their “time” on the two planets. They will then create a newspaper article or news report script that strives to help their audience understand what life is like in this deep-space colony.

Estimated time required: 1-2 class periods.

Technology required for this lesson: Laptop/Desktop, Tablet.

Kevin and his grandfather, Omag are going to the zoo. Join them and learn all about animal classification and life cycles.

In this video produced for Teachers' Domain, Chi-An Wang, a mechanical engineering graduate from the Massachusetts Institute of Technology, describes her process when working with New Balance to design a new triathlon shoe.

In this video from Science City, meet Eduardo Torres-Jara, a postdoctoral associate in electrical engineering and computer science at the MIT Artificial Intelligence Lab. He describes his work on innovative robots that use tactile feedback to locate and grasp objects.

In this video produced by ThinkTV, explore the effects of land masses on local climate conditions, and learn about regional impacts of land-atmosphere interactions.

In this video segment adapted from NOVA scienceNOW, scientists examine the link between rising sea surface temperature and more intense hurricanes.

In this media-rich lesson, students learn how global warming is changing the Alaskan environment and examine the consequences of climate change on the region's human and wildlife inhabitants.

Ali really loves to make music. Help make Ali's dream come true. Together, answer questions about musical instruments.

This video, adapted from NASA, presents rare experimental evidence from the Fermi Gamma-ray Space Telescope supporting Einstein's prediction that space-time is smooth.

During the lesson, students will learn the basics of electricity and circuits and build their first circuit using Snap Circuits. If students do not have access to Snap Circuits, this lesson can be completed using anything that provides students the ability to connect the following components: Power source ( 9V battery); Conductive material (wires, aluminum foil, paper clips, etc.); An “output” device for the electricity (flashlight lightbulb or holiday light); A switch (two metal thumbtacks and a paper clip, aluminum foil and a paper clip, etc.).

Estimated time required: 1-2 class periods.

Technology required for this lesson: Electronics Kit, Laptop/Desktop, Tablet.

During the lesson, students will learn about series and parallel circuits and how they are used for different purposes. If students do not have access to Snap Circuits, this lesson can be completed using safe household materials that provide students the ability to connect the following components: Power source ( 9V battery); Conductive material (wires, aluminum foil, paper clips, etc.); An “output” device for the electricity (flashlight lightbulb or holiday light); A switch (two metal thumbtacks and a paper clip, aluminum foil and a paper clip, etc.).
