Mud Fossils

Learn about fossil preservation, paleontology, and stratigraphy in this detailed activity from the USGS.

Mystery Mollusc

Pretend to be a biologist as you 'discover' a new mollusc species and work to determine it's characteristics and habitat.

Natural Gas Formation

Natural gas, which is mostly methane, is an energy resource used for generating electricity and heating, powering transportation, and manufacturing products. Right now, one-quarter of the world’s energy comes from natural gas. In this investigation, you will make a simple model of how gases can form from decaying material. You will also explore the effects of temperature on gas formation.

Nitrogen Connection

All biological organisms require certain nutrients to live. Plants require carbon, hydrogen, and oxygen from air and water, as well as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, copper, zinc, nickel, chloride, boron, and molybdenum from soil. Animals require a few others. Conversions and transformations of nutrients in the environment result from chemical reactions, biological activity, or both.

Ocean Acidification

The ocean is a “carbon sink,” which means that it removes CO2 (carbon dioxide) from the atmosphere. The ocean currently absorbs about one-third of the CO2 released by the burning of fossil fuels.

However, beyond a certain level of atmospheric CO2, the ocean can no longer act as a carbon sink without it having a negative impact on marine life. When CO2 dissolves in seawater, it leads to decreased pH levels. The ocean becomes less alkaline. This is referred to as ocean acidification.

Ocean Currents

In this activity, students will learn the pattern of major ocean currents and how they are changed by wind, land and water.

Ocean Currents Change Our Earth

Ocean currents — the continuous, directed movement of ocean water — affect regional climates and alter the biological and chemical characteristics of seawater.

Oil Trap Model

Discuss how a 3-D model illustrates the geology of oil deposits. What challenges do you think petroleum geologists must overcome to recover oil?

Painting With Soil

Soils are one of our most important natural resources — just think of where all the food you eat comes from. They also are important for the beauty the many soil colors add to our landscapes.

Most of us overlook this natural beauty because we see it every day. Often these colors blend with vegetation, sky, water, etc. Soil colors serve as pigments in bricks, pottery and artwork.  The color and texture of soil painting is fascinating and a creative opportunity for all ages of students.
