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.
This lesson on earthquakes is based on naturalist John Muir's experiences with …
This lesson on earthquakes is based on naturalist John Muir's experiences with two significant earthquakes, the 1872 earthquake on the east side of the Sierra Nevada Mountains, and the Great San Francisco Earthquake of 1906. Students will learn to explain that earthquakes are sudden motions along breaks in the crust called faults, and list the major geologic events including earthquakes, volcanic eruptions and mountain building, which are the result of crustal plate motions. A downloadable, printable version (PDF) of the lesson plan is available.

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.
In this video segment adapted from NOVA, a geologist digs a trench …
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 …
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 activity uses the free software 'Seismic Eruption' to visualize seismicity and …
This activity uses the free software 'Seismic Eruption' to visualize seismicity and volcanic activity in space and time and to explore the relationship of earthquakes and volcanic activiy to plate tectonics. Students run simulations on the Pacific coasts of South America and California and the mid-oceanic ridge in the Atlantic Ocean, answer questions, and construct a cross-section. A link to download the software is provided.

This module explores the composition of the earth's atmosphere, how temperature and pressure vary in the atmosphere, and the scientific developments that led to an understanding of these basic concepts.

Students will begin this inquiry-based lesson by accessing their prior knowledge of the positive and negative effects of the sun's energy. Students will be introduced to the concept of space weather, including cosmic radiation and coronal mass ejections, by watching a video clip from the National Science Foundation. Students will use a dipole bar magnet and iron filings to develop a model of Earth's magnetic field. Students will apply their experience from this inquiry to explain how Earth's magnetic field can protect us from space weather. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.

In this interdisciplinary lesson about solar and lunar eclipses, students will model …
In this interdisciplinary lesson about solar and lunar eclipses, students will model and determine the difference between the two eclipses. It involves components of the Sun- Earth- Moon system with NASA resources, hands-on inquiry, and observational data. This lesson results from a collaboration between the Alabama State Departments of Education and ASTA.

In this activity, students conduct experiments using an egg and a graduated cylinder filled with liquids of different densities. By observing how different densities affect the egg's position in the cylinder, they can draw important connections to the Earth's lithosphere, hydrosphere, and atmosphere.
The purpose of this activity is to recreate the classic egg-drop experiment …
The purpose of this activity is to recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and students will perform several velocity calculations. Also, students will have to design and build their lander within a pre-determined budget to help reinforce a real-world design scenario.

This book offers an introduction to the electromagnetic spectrum using examples of data from a variety of NASA missions and satellite technologies. The 84 problem sets included allow students to explore the concepts of waves, wavelength, frequency, and speed; the Doppler Shift; light; and the energy carried by photons in various bands of the spectrum. Extensive background information is provided which describes the nature of electromagnetic radiation.
