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.
Fossil fuels play an important role in allowing us to have lifestyles we’re accustomed to, but they do emit carbon dioxide, and we all want to be good stewards of our resources. The goal of this activity is to become aware of how much energy you use at school — and the financial and environmental costs.
You may have seen or used Global Positioning System (GPS) devices in cars or on camping trips. These devices use data from satellites orbiting the Earth to locate places on our planet. GPS devices describe the locations to us in the form of latitude and longitude coordinates.
Static electricity can be used to demonstrate the electricity of lightning. This activity will demonstrate the attraction of positive and negative charges and what happens when those opposite charges meet each other.
Dendrochronologists use tree rings to go back in time to learn more about past climate. Using straws to recreate tree rings, you can learn how dendrochronologists work.
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.
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.
Learn the characteristics of difference kinds of minerals in this hands on investigative activity.
A normal fault occurs when rocks break and move because they are being pulled apart. As the area is stretched, the rocks move along the fault. Each movement causes an earthquake. This model demonstrates how a block of rock is extended by a normal fault.
