Learn about the Earth's magnetic poles and paleomagnetism in this activity from Consortium for Ocean Leadership.
When warm and cold air masses meet, a thunderstorm can grow. Thunderstorms also cause heavy rain, flash flooding, hail, strong winds and tornadoes. In this activity, you will learn about convection and how air moves.
Learn how to make a compass using household objects!
Make your own Powers of Ten film like the classic science education movie by Charles and Ray Eames!
We usually think of caves forming as rocks are dissolved and the particles are washed away, leaving hollow spaces behind. This activity simulates the way that dissolution, a chemical weathering process, leads to the formation of caves.
The sun rises in the east and sets in the west. This we know from personal observation. But have you ever thought about where the sun is in the sky at the same time each day?
You might think the sun would appear at the same place at the same time each day. This would be true if Earth had no tilt and its orbit were a perfect circle. But this is not the case.
In this investigation, you'll have the opportunity to learn about the many geological features in our country's national parks. You might not realize this, but a large number of the national parks were created because of their amazing geology. Just think of the geological features of Yellowstone National Park, the Grand Canyon, Hawaii Volcanoes National Park, and many more!
Maps are two-dimensional ways of representing information about the natural and built world from a "top-down" perspective. You are probably familiar with road maps that show where roads go and which roads intersect with others and where. You also may have seen weather maps, which show weather patterns across a specific geographic area, or political maps, which show where borders are for countries and areas within those countries.
A refuge is a place where you can record observations of seasonal changes to plants, trees, and wildlife. You can use GPS (global positioning system) data to mark an observation spot and record your observations. Then, if you can, visit the same national wildlife refuge during other seasons in the year to document changes in the natural world.
Today, people are “mapping our world” with the aid of Geographic Information Systems (GIS) technology. Mapping can be done in the field or the lab—even from smartphones. You can make maps with real-time data about wildfires, tsunamis, and tornadoes. You can make maps with imagery collected with visible light, infrared, and radar data.
