Students learn what causes earthquakes, how we measure and locate them, and their effects and consequences. Through the online Earthquakes Living Lab, student pairs explore various types of seismic waves and the differences between shear waves and compressional waves. They conduct research using the portion of the living lab that focuses primarily on the instruments, methods and data used to measure and locate earthquakes. Using real-time U.S. Geological Survey (USGS) data accessed through the living lab interface, students locate where earthquakes are occurring and how frequently. Students propose questions and analyze the real-world seismic data to find answers and form conclusions. They are asked to think critically about why earthquakes occur and how knowledge about earthquakes can be helpful to engineers. A worksheet serves as a student guide for the activity.

Students learn how engineers characterize earthquakes through seismic data. Then, acting as engineers, they use real-world seismograph data and a tutorial/simulation accessed through the Earthquakes Living Lab to locate earthquake epicenters via triangulation and determine earthquake magnitudes. Student pairs examine seismic waves, S waves and P waves recorded on seismograms, measuring the key S-P interval. Students then determine the maximum S wave amplitudes in order to determine earthquake magnitude, a measure of the amount of energy released. Students consider how engineers might use and implement seismic data in their design work. A worksheet serves as a student guide for the activity.

Students study how geology relates to the frequency of large-magnitude earthquakes in Japan. Using the online resources provided through the Earthquakes Living Lab, students investigate reasons why large earthquakes occur in this region, drawing conclusions from tectonic plate structures and the locations of fault lines. Working in pairs, students explore the 1995 Kobe earthquake, why it happened and the destruction it caused. Students also think like engineers to predict where other earthquakes are likely to occur and what precautions might be taken. A worksheet serves as a student guide for the activity.

Students examine the effects of geology on earthquake magnitudes and how engineers anticipate and prepare for these effects. Using information provided through the Earthquakes Living Lab interface, students investigate how geology, specifically soil type, can amplify the magnitude of earthquakes and their consequences. Students look in-depth at the historical 1906 San Francisco earthquake and its destruction thorough photographs and data. They compare the 1906 California earthquake to another historical earthquake in Kobe, Japan, looking at the geological differences and impacts in the two regions, and learning how engineers, geologists and seismologists work to predict earthquakes and minimize calamity. A worksheet serves as a student guide for the activity.

Students use U.S. Geological Survey (USGS) real-time, real-world seismic data from around the planet to identify where earthquakes occur and look for trends in earthquake activity. They explore where and why earthquakes occur, learning about faults and how they influence earthquakes. Looking at the interactive maps and the data, students use Microsoft® Excel® to conduct detailed analysis of the most-recent 25 earthquakes; they calculate mean, median, mode of the data set, as well as identify the minimum and maximum magnitudes. Students compare their predictions with the physical data, and look for trends to and patterns in the data. A worksheet serves as a student guide for the activity.

Students gather evidence to explain the theory of plate tectonics. Using the online resources at the Earthquakes Living Lab, students examine information and gather evidence supporting the theory. They also look at how volcanoes and earthquakes are explained by tectonic plate movement, and how engineers use this information. Working in pairs, students think like engineers and connect what they understand about the theory of plate tectonics to the design of structures for earthquake-resistance. A worksheet serves as a student guide for the activity.

Students learn the two main methods to measure earthquakes, the Richter Scale and the Mercalli Scale. They make a model of a seismograph a measuring device that records an earthquake on a seismogram. Students also investigate which structural designs are most likely to survive an earthquake. And, they illustrate an informational guide to the Mercalli Scale.

In this activity, learners draw a circle with a single focus, an ellipse with two foci close together, and an ellipse with two foci far apart, and compare the shapes. Learners then measure the Sun in four images each taken in a different season, comparing the apparent size of the Sun in each image to determine when Earth is closest to the Sun. This is the second activity in the SDO Secondary Learning Unit. The activity is reprinted with permission from the Great Explorations in Math and Science (GEMS).

Each year, Earth makes a complete trip around the Sun! Learn about our planet’s journey and important points along its orbit. Visit the two websites listed to find clues to solve this crossword puzzle!

To gain an understanding of mixtures and the concept of separation of mixtures, students use strong magnets to find the element of iron in iron-fortified breakfast cereal flakes. Through this activity, they see how the iron component of this heterogeneous mixture (cereal) retains its properties and can thus be separated by physical means.

In this activity, students will experience echolocation themselves. They actually try echolocation by wearing blindfolds while another student makes snapping noises in front of, behind, or to the side of them.

In the world of ecology, the only constant is change - but change can be good. Today Hank explains ecological succession and how ecological communities change over time to become beautiful, biodiverse mosaics.

Hank introduces us to ecology - the study of the rules of engagement for all of us earthlings - which seeks to explain why the world looks and acts the way it does. The world is crammed with things, both animate and not, that have been interacting with each other all the time, every day, since life on this planet began, and these interactions depend mostly on just two things... Learn what they are as Crash Course Biology takes its final voyage outside the body and into the entire world.

This week we’ll see how economies can be broken down into the primary, secondary, and tertiary sectors. We’ll look at the three stages of economic revolution that brought us to the modern post-industrial era. We’ll also explore two types of economic models: capitalism and socialism.

Hank brings us to the next level of ecological study with ecosystem ecology, which looks at how energy, nutrients, and materials are getting shuffled around within an ecosystem (a collection of living and nonliving things interacting in a specific place), and which basically comes down to who is eating who.
