Plant an Ozone Monitoring Garden

Students can monitor local ozone by looking in their neighborhoods for ozone-injured plants or establishing similar gardens outside their schools or in their backyards.

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?

Test Basic Page

Since October 1998, the American Geosciences Institute has organized this national and international event to help the public gain a better understanding and appreciation for the Earth Sciences and to encourage stewardship of the Earth. This year's Earth Science Week will be held from October 9-16, 2016 and will celebrate the theme "Our Shared Geoheritage." Geoheritage is the collection of natural wonders, landforms, and resources that have formed over eons and come to this generation to manage, use, and conserve effectively.

Traveling Nitrogen

Nitrogen is an element that is found both in living things and the nonliving parts of the Earth system. In this classroom activity, students play the role of nitrogen atoms traveling through the nitrogen cycle to gain understanding of the varied pathways through the cycle and how nitrogen is relevant to living things.

Tree Rings and Ancient Climatic Conditions

How do archaeologists learn about climatic conditions and their effects on people in the past? In 1815, Mount Tambora in Indonesia erupted so violently that the sound of the eruption could be heard 1,600 miles away. Gases from the volcano shot into the stratosphere almost six miles above the Earth’s surface and lingered for years. Sulfur dioxide combined with water molecules to form sulfate particles that reflected sunlight away from Earth, gradually causing the planet’s surface to cool. The colder temperatures caused severe weather events worldwide.

Understanding Paleoclimate

Climate scientists study evidence in the geologic record, such as fossils, to figure out what climate was like over hundreds of thousands of years (“paleoclimate”). One fossil they use is pollen, a part of a flowering plant that helps make a seed. Pollen can be blown into lakes, where it is preserved in sediment. Pollen from spruces, which do well in cold climates, can suggest what climate was like when spruce pollen was deposited.

Your Own Greenhouse

Climate scientists around the world study greenhouse gases and the ways they affect global climate. By making your own small greenhouse in this activity, you can recreate the greenhouse effect and measure its effect on temperature.
