Map-Making Basics

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.

Mud Fossils

Places on the Planet: Latitude and Longitude

Citizen scientists involved in the Geological Society of America's EarthCaching project (http://www.earthcache.org) use GPS technology and latitude and longitude coordinates to find special places on the Earth. This activity will help you learn how to find locations using latitude and longitude.

Tracking Dinosaurs

Paleontologists are the geoscientists who discover and study fossil evidence of past life. Sometimes they even find the footprints of dinosaurs that roamed the surface of the Earth long ago. Ever wonder how paleontologists are able to determine, based on fossil evidence, whether a particular dinosaur was walking or running when it left footprints behind? These two activities will help you to learn how these scientists can do that.

Traveling Nitrogen

Nitrogen is an element that is found both in living things and the nonliving parts of the Earth system. In this classroom activity, students play the role of nitrogen atoms traveling through the nitrogen cycle to gain understanding of the varied pathways through the cycle and how nitrogen is relevant to living things.
