Climate and Temperature Activity Source: Soil Science Society of America. Adapted with permission. There are many factors that combine to form soil, an important, slowly renewable resource. Some of these factors include climate, organisms, relief, parent material, and time. Soil provides the food, fiber, and building materials to nourish, clothe, and house Earth’s inhabitants. How does climate help soil to form? In warm, moist climates such as those in tropical rainforests, organic (formerly living) material breaks down most quickly. [Read More]

Collecting Real World Data Activity Source: National Aeronautics and Space Administration. Adapted with permission. Scientists collect data to understand Earth and how it changes. Quantitative data involves taking measurements, while qualitative data are observations and descriptions of phenomena. When it comes to climate, scientists try to collect as much and as many types of data as possible to be able to analyze how climate is changing and what effects it is having. [Read More]

Connecting With Nature Activity Source: Adapted with permission by U.S. Fish & Wildlife Service The “Blue Goose” has been the symbol of the National Wildlife Refuge System since it was first drawn by Pulitzer Prize-winning cartoonist J.N. “Ding” Darling, one of the greatest supporters of wildlife conservation in the 20th century. President Theodore Roosevelt designated Florida’s Pelican Island as the first wildlife refuge in 1903. Now the National Wildlife Refuge System includes more than 550 refuges. [Read More]

Dangerous Atmosphere Activity Source: Adapted with permission by The Weather Channel. Background How much of a danger does severe weather pose for the area where you live? You can compute the answer yourself in the exercise below. You may want to divide up tasks 6-13, one per student, and then compare results. Materials A computer with Internet access Paper and pen to record findings Procedure 1. Identify your state and county. [Read More]

Engineer a Satellite Activity Source: NASA. Adapted with permission. Is the ozone hole getting smaller? How much rain is in the cloud of a hurricane? How much sea ice is melting in the Arctic? For over 50 years, NASA scientists have been asking questions and collecting data from space-based satellites to study Earth’s changing environment. Engineers and scientists are essential partners in this process. From the scientists’ questions, engineers help design instruments to get the measurements needed to help answer these questions.

Exploring Change with GIS Activity Source: ESRI. Adapted with permission. On our ever-changing Earth, conditions may change quickly or slowly. Some changes come from natural processes; some from human activity. Satellites allow us to see conditions and track changes over time — in land use, forest health, land/water interface, and so on. Since 1972, Landsat satellites have been collecting data using various portions of the visible and invisible electromagnetic spectrum, at a scale close enough to see highways, but not individual buildings on a city block.

Exploring Climate Change with GIS Activity Source: ESRI. Adapted with permission. Earth’s climate is a product of and is affected by many things—and it’s changing. Long-term and short-term processes, such as plate tectonics and volcanism, contribute to climate. Likewise, human influences, such as rising CO2 levels from fossil fuel burning and deforestation, play active roles. The expression of climate change is seen in a variety of forms: Erratic weather patterns and rising sea levels are among the most discussed. [Read More]

Exploring Color Maps Activity Source: NASA. Adapted with permission. Blue landmasses? Green clouds? Red ice shelves? Maybe you’ve seen a colorful map and said to yourself, that’s not how it looks in real life! A color-mapped image may have puzzling colors like these because scientists used different colors to represent data. Color is one of the tools that scientists use to visualize data about complex phenomena, from storm intensity to land surface temperature or the heights of underwater geologic formations.

Geologic Age Activity Source: Adapted from the USGS Learning Web Lesson Plans Background At the close of the 18th century, the haze of fantasy and mysticism that tended to obscure the true nature of the Earth was being swept away. Careful studies by scientists showed that rocks had diverse origins. Some rock layers, containing clearly identifiable fossil remains of fish and other forms of aquatic animal and plant life, originally formed in the ocean. [Read More]

Geologic Time Scale Analogy Activity Source: Ritger, S.D. and R.H. Cummins. 1991. Using student-created metaphors to comprehend geologic time. Journal of Geological Education. 9:9-11. Purpose To introduce students to the vastness of [geologic time](/content/geological- time-scale) and the concept of scale. Background 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. [Read More]
