In this lesson, students observe a teacher-directed demonstration that provides a conceptual understanding of latent heat, the "hidden heat" present in all changes from one phase to another, by using a hand warmer. Full description.

This demonstration is designed to show the effect of acid on statues and buildings. Students will learn how acid rain is an air pollution problem as the teacher discusses the slow deterioration of statues and buildings due to the weak acid rain that falls on them. Students will learn that the sulfur and nitrogen compounds that contribute to acid rain primarily come from man-made sources, such as industries ... Full description.

This program provides scientific research and assessment to evaluate the effects of atmospheric deposition on aquatic and terrestrial ecosystems. A clickable map depicts locations of acid rain monitoring stations by state. This site also contains reports presenting data on acid rain trends and monitoring efforts as well as research performed on acid rain accumulation values. Information is also available ...

Resources available from this site include: a Word Search; Masterbug Theater, which is a slideshow about the metamorphosis of Macroinvertebrate indicators in a freshwater aquatic environment; and Darby Duck and the Aquatic Crusaders, which contains experiments about the properties of water. What's Wrong With This Picture allows students to identify several sources of pollution in a suburban environment ... Full description.

The Wildland Fire Management RD&A gathered statistics from the Wildland Fire Management Decision Support System (WFDSS) and other sources to build a comparative summary of the 2011 and 2012 fire seasons. (The comparison only included federal fires occurring on federal lands throughout each fiscal year.) The purpose of this information is to illustrate potential contributing environmental factors ...

The goal of this presentation is to introduce effective questions and provide evidence-based information to build an understanding of science related to the Marcellus Shale, a black shale formation extending deep underground from Ohio and West Virginia northeast into Pennsylvania and southern New York. Recent technological advances and elevated natural gas pricing has made extraction very attractive ... Full description.

This demonstration introduces the concept of water phases and cycling to younger students through observation, drawing, and writing. They will be able to explain how the Earth's water supply is recycled, form a hypothesis as to how/why the water cycle works, and use writing and drawing to explain how the cycle works. Full description.

This PowerPoint presentation on the fundamentals of wind tunnel testing provides ideas for sample experiments; explanations of lift, drag, governing equations, how to make measurements, flow visualization techniques, and types of wind tunnels; and reasons for testing in wind tunnels. Full description.

These demonstrations are designed to help students develop a conceptual understanding of geophysical principles. The concepts covered in these demonstrations include rheology, seismic waves, reflection, standing waves, velocity, earthquakes, Earth density, magnetic field, resonance, precession, the shadow zone, and Curie temperature. Each demonstration provides background information and a complete ... Full description.
