Properties of Fresh Water and Sea Water

The students will set up three demonstrations to observe the properties of water. They will explore the boiling point of water, the freezing point of water, and the ability of water to store heat. These activities can be done individually or as a set.

Rock Abrasion

Rocks break down into smaller pieces through weathering. Rocks and sediment grinding against each other wear away surfaces. This type of weathering is called abrasion, and it happens as wind and water rush over rocks. The rocks become smoother as rough and jagged edges break off. In this activity, you will model how abrasion works.

Seismic Calendar

This activity allows you to investigate how often earthquakes of various magnitudes happen within a geographic region of your choice. You will use the online resources of the Incorporated Research Institutions for Seismology (IRIS) to do the investigation. These resources are available at http://www.iris.edu

ShakeAlert Earthquake Early Warning

Have you ever felt an earthquake? What was it like? Where were you? What did you do? More than 143 million people are exposed to potentially damaging shaking in the United States.

Soil Color and Redox Chemistry

Are soils like M&Ms™? Yes! Find out more in this awesome activity provided by the Soil Science Society of America.

Soil Moisture

Where is the water in soil? Solids, liquids, and gasses, the three phases of matter, are always present in soil. Small mineral and organic particles comprise the solid fraction, and there are spaces (pores) between the solid particles. Some pores are large, and others are very small. Air and water, the gas and liquid phases, exist in the pores. The size of the soil particles and pores affects how much water a soil can hold, and how that water moves through the soil.

Soil, Plants, and the Energy Cycle

Soils are critical for many aspects of our daily life. They provide food such as grains, vegetables, and animal feed. They provide fiber for clothing, as in cotton, flax-linen, and hemp. And they provide shelter materials like wood and brick. But did you realize that soils also are an important part of the energy cycle?

Solar Cell Energy Nationwide

MY NASA DATA microsets are created using data from NASA Earth science satellite missions. A microset is a small amount of data extracted from a much larger data file. Data is available on the atmosphere, biosphere, cryosphere, ocean, and land surface. Data and related lessons can be used with existing curriculum to help students practice science inquiry and math or technology skills using real measurements of Earth system variables and processes. In this activity, students use NASA data to determine areas of the country that are most likely to produce solar energy by analyzing differences in incoming solar radiation graphs.

Space Archaeology

Want to be an archaeologist without leaving your school? No problem! Use a computer to become a space archaeologist (no spacesuit required)!

Surficial Features

Various types of sediments, or “surficial features,” lie above the bedrock in many places. The following activity shows how a visualization map of surficial features can be used to consider the interactions of the geosphere, hydrosphere, biosphere, and atmosphere.
