The ocean is the key element in Earth's hydrologic cycle (water cycle). Students will construct a simple model of the hydrologic cycle to help them visualize and understand the movement of liquid water and heat.
If you have ever used Google Earth, what was the first place you tried to find? For many people the answer is “my home.” Where humans choose to live is one of the fundamental influences on the surface of our planet.
EarthCaching is an exciting educational activity through which you can learn about Earth and the natural processes that shape our planet over time. By combining GPS technology with outdoor field experiences, EarthCaching allows students and others to experience the wonders of Earth in an entirely new and entertaining way.
An earthquake simulation activity from IRIS.
Push away from those paper seismograms and get outside to make your own earthquake waves! You're going to learn about earthquake location kinesthetically. In the activity below, you will model how earthquake waves travel through the Earth at different speeds. You also will construct and utilize a graph to characterize the relationship between distance and time of travel of seismic waves (a travel-time curve). Finally, you'll use the constructed travel-time curves to locate the epicenter of a simulated earthquake by triangulation.
If you found yourself in the middle of the ocean, do you think you could find your way home? Sea turtles can, thanks in part to Earth’s magnetic field!
For teachers and educators: Earth Science Week 2020 will be celebrated from October 11-17, with the theme "Earth Materials in Our Lives." During Earth Science Week, we hope that you will bring some aspect of Earth Science into your classroom, and take your classroom outside! Your students will not only learn something new about the world around them, but will have fun discovering why Earth Science is important to society.
Just as your GPS helps you make sure you’re getting from point “a” to point “b” correctly, maps help scientists draw important conclusions and visualize important concepts they study. The right map can help a petroleum engineer find the best drilling site, or help a meteorologist make the best prediction. This interactive mapping activity will help you understand the relationship between the population of a given state and the amount of energy consumed there.
Even in an area with an extreme climate, the ground maintains a relatively constant temperature. Because of this, a house that is built partly or entirely underground can be more energy-efficient than a home above ground. During the winter, the ground is warmer than the air. During the summer, it is cooler. Any large mass of earth tends to maintain a constant temperature. You can see for yourself how this works by testing how long it takes for a thermometer buried in sand or soil to reach the temperature of surrounding air.
In this activity, you will select the scientific instruments for your satellite, calculate the power requirements for all the subsystems, and construct a scale model of your very own Earth observing satellite.
