This activity will have students collect data, graph it, and compare the information to what they already know about radioactive elements and dating the planet's age.
Geologic Time Scale Analogy
Unraveling time and the Earth's biologic history are arguably geology's most important contributions to humanity. Yet it is very difficult for humans to appreciate time beyond that of one or two generations, much less hundreds, thousands, millions and billions of years. Perhaps we can only hope that students catch glimpses of our rich geologic heritage, particularly when most of our teaching is done in a classroom and not in a field setting. This exercise begins to make time more "three dimensional" and most importantly, students gain a better appreciation for geologic time and our Earth's history.
Glaciers can create lakes, valleys and areas known as kettle marshes. Their weight and movement are the tools a glacier uses to shape the landscape. Use this experiment to look at small "glaciers" and how they shape the landscape around them.
It's About Time
Geologic time can be difficult for people to understand. Our own lives are so short when we compare them to the age of the Earth, that the hundreds of millions of years of geologic time are almost too much to grasp. To understand how a timeline works, you will make a personal timeline and compare it to the geologic timeline shown here.
It’s the “Rain,” Man
People find inspiration in many different places and things. Among them is taking joy in sensing the Earth around you. Feel the breeze on your face. Take in the fresh smell of the air after a spring rain. Use your hands to build something. Wherever you live you can get outside, savor your surroundings and observe what makes up the rhythms of the place you live.
Looking for Wild Elements
In this activity, students will explore local places with wild elements, such as wildlife refuges. Students also will create maps showing spatial relationships between wild places and school, and they will find creative ways to record experiences.
Magnets at the Core
Learn about the Earth's magnetic poles and paleomagnetism in this activity from Consortium for Ocean Leadership.
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.
Mapping a Refuge
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.
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.
