This video segment adapted from NASA's Goddard Space Flight Center explains how hurricanes develop and why there are fewer hurricanes in the Atlantic Ocean in strong El Niño years.

This video segment adapted from NASA's Goddard Space Flight Center shows how integral satellites are to everyday life and describes the different types, including orbital and geostationary.

This interactive activity from the Adler Planetarium explains the reasons for the seasons. Featured is a game in which Earth must be properly placed in its orbit in order to send Max, the host, to different parts of the world during particular seasons.

This video segment adapted from NOVA tells the tragic story of two Japanese seismologists who disagreed about the threat of earthquakes in the early twentieth century. Today, seismologists in California offer residents a probability of risk that an earthquake might occur.

In this video segment adapted from NOVA, animations are used to show how the hills around Los Angeles were formed by earthquakes at small thrust faults that extend outward from the larger San Andreas fault.

The history of earthquakes in the San Francisco Bay area is plotted on a digital map and analyzed in this video segment adapted from NOVA.

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.

In this problem students practice basic addition and subtraction skills along with logical reasoning to satisfy three interdependent conditions. Solvers use the clues provided to determine the number of eggs in each of three baskets. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, ideas for extension and support, a PowerPoint presentation, and vocabulary cards (pdf).

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.

Students model, build, and draw diagrams of electric circuits and test the conductivity of a variety of materials.

Play ball! Add charges to the Field of Dreams and see how they react to the electric field. Turn on a background electric field and adjust the direction and magnitude. (Kevin Costner not included).

The aim of this lesson is to introduce the concepts of Electrochemistry and Electroplating and to present their applications in our daily lives. Students are encouraged to construct their knowledge of Electroplating through brainstorming sessions, experiments and discussions. This video lesson presents a series of stories related to Electroplating and begins with a story about house gates as an example of the common items related to the Electroplating topic. Prerequisites for this lesson are knowledge of the basic concepts of electrolysis and chemical equations. The lesson will take about 60 minutes to complete, but you may want to divide the lesson into two classes if the activities require more time.

In this animation produced by WGBH and Digizyme, Inc., see how molecules of DNA are separated using gel electrophoresis, and how this process enables scientists to compare the molecular variations of two or more DNA samples.

In this lesson designed to enhance literacy skills, students examine energy forms in moving objects and discover how changes from one form to another move cars through a roller coaster ride.

On NOVA, a team of carpenters, timber framers, engineers, and historians recreate a medieval throwing machine called a trebuchet. This adapted video segment explores how understanding energy transfer informs their design.

In this video segment from NASA, robotics researcher Ayanna Howard uses engineering to improve the intelligence of robots in space exploration.

This article aligns the concepts of Essential Principle 2 of the Climate Sciences to the K-5 content standards of the National Science Education Standards. The author also identifies common misconceptions about heat and the greenhouse gases effect and offers resources for assessing students' understanding of interactions among components of the Earth system. This article continues the examination of the climate sciences and climate literacy on which the online magazine Beyond Weather and the Water Cycle is structured.

In this NASA video, scientists describe how the Extreme Ultraviolet Variability Experiment will sample and track the Sun's ultraviolet irradiance, providing a detailed time sequence of extreme ultraviolet output -- data that can provide advance warning for potentially disruptive energy bursts.

In this adapted video segment, ZOOM guest Tommy takes us on a tour of the Florida Everglades. He describes what makes a wetland biome unique, including the soil, precipitation, and biodiversity.
