The goal of this activity is to identify the watershed you live in, the source of water you use at home and the pathway of surface water runoff in your watershed.
Water is often called a renewable resource, but what does that really mean? Is water an unlimited resource? What happens to water after we use it? This investigation will help you understand exactly how much water you use in your home and how you can keep from wasting water. If many people are participating in this investigation, work in small groups of 3-5. Before you begin, think about all the ways water is used in your home. How much water do you and your family use at home everyday? Record your thoughts and share them with others. Make a list that combines everyone’s uses of water in their homes.
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.
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.
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.
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.
