Students work together to discuss seismic waves. Using seismograph records, they practice determining where the epicenter of the earthquake was located. They identify and illustrate the three types of waves and how the records can be...

Students discover the differences between P- and S-waves using a slinky. They see that when displacement occurs along a fault, the built up strain of energy is released in the form of seismic waves.

Here is a scientific presentation of earthquakes. The elastic rebound theory is explained, as well as the different types of waves and how they are measured. Just a note: Slide number 15 has a diagram that is upside down. Enable editing...

Students engage in an interactive Internet lesson covering the reasons and results of earthquakes. After reading eyewitness accounts and viewing animations, they use seismograms to measure and locate the epicenters. In an ongoing study,...

In this earth and space science worksheet, students complete a crossword puzzle given 7 clues and a word bank about the solar system, earthquakes, currents and the Earth's crust.

In this earth and space science worksheet, students complete a crossword puzzle given 7 clues and a word bank on topics such as earthquakes, erosion, galaxies and weathering.

Student, use seismic readings of the same earthquake from three recording stations and locate the epicenter of an earthquake on a map.

Ninth graders differentiate between energy waves transmitted from a quarry or mine as opposed to energy waves transmitted by an earthquake. They analyze seismograms of blast events from at least two quarries or mines. The energy waves...

Young scholars grasp how underwater animals can "see" using sound waves. They practice making inferences, and build a conceptual understanding of sonar radar.

Readers use context to determine the meaning of words found in a short article about earthquakes and the movement of the earth's crust.

Lead your class to construct a solar still on campus to demonstrate how water can be extracted from the soil. The power of solar energy is emphasized, as is the concept of how capillary water can be recovered and purified by using a...

Young scholars make observations through 3-D visualizations. They explore scientific and geologic processes through the use of 3-D pictures.

Transform your class into young geologists as they learn about six different branches of geology. Using the included geology career descriptions and picture cards, learners work in small groups deciding which tools and locations fit...

In this earthquakes worksheet, students learn about the measurements of earthquakes on the Richter scale. They answer six questions about the magnitudes and sizes of earthquakes using two tables of data about earthquakes and the Richter...

Students work together to use a sample seismograph. They role play the position of an engineering firm that is to analyze the machine. They discover how engineers develop new machines to take measurements.

Sixth graders write research reports about trains. They focus on mechanical features of trains.

In this interactive tutorial you will learn about earthquakes and seismic waves. Learn about why and how these form and also discuss the hazards - direct and indirect - posed by earthquakes. You will then learn how our knowledge of...

The paths of some seismic waves and the ground motion that resulted are shown in this poster.

See how seismic waves propagate outwards, as wave fronts, in all directions following an earthquake.

A quick, introductory lesson about how earthquakes happen, and what impact these natural events have on life.
