Investigating Soil

Investigate different types of soil by using a core sample.

Investigating Water Use in Your Home

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.

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.

Know Your Energy Costs

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.

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.

Making Your Own National Park Geologic Tour

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!

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.

Measure for Measure

Geoscientists use special boats to conduct research at sea. One of these boats is named the JOIDES Resolution (JR). Unlike most oceangoing vessels, the JR has a flat bottom, a 6.4-meter hole in the middle, 12 laboratories, and a derrick towering 67 meters above the waterline! Why? So scientists can sail nearly anywhere in the world to drill for samples of rocks and sediment from below the seafloor. What for? In hopes of discovering clues about Earth's history and structure, life in the deep biosphere, past climate change, earthquakes and natural resources.

Model of a Well

Groundwater is contained in the zone of saturation below the land surface. The top of this zone is known as the water table. People can tap into this source of water by drilling wells. The depth of the well and level of the water table greatly influences the wells productivity. In this activity you will demonstrate the relationship of groundwater to wells.
