Sun's Impact on Earth's Temperature
In this activity, middle school students view NASA images and movies of Venus, Earth, and Mars to deduce weather patterns and manipulate computer models to test competing hypotheses. By completing this activity, the learner will compare weather patterns observed on Venus, Earth, and Mars; manipulate computer models to investigate the influence of solar distance and atmosphere; evaluate various solar system hypotheses using a computer model.
Atmosphere Applet: This program lets you study how the properties of the atmosphere change with altitude. You can study the atmosphere of either the Earth or Mars. The equations used in this program are taken from the ICAO standard day model for the Earth and from some curve fits of the Martian atmosphere gathered by the Global Surveyor spacecraft. Using the airplane graphic you can select an altitude, or you can type an altitude into the input box. The program instantly outputs a selected pro
Undergraduate Computer Programs
Here is a group of Java programs which were designed to help undergraduate engineering students. These programs cover the basics of aerodynamics and propulsion. The icon at the top of each section will take you to a web page which contains a simulator or calculator for an aerodynamics problem. The web page assumes that you understand the problem and contains only the applet and a couple of hyperlinks to additional pages which describe the science and math behind each problem and some additional
EngineSim and RangeGames Downloads
EngineSim was developed at the NASA Glenn Research Center in an effort to foster hands-on, inquiry-based learning in science and math. EngineSim is a simulator that models the design and testing of jet engines. The program works in two modes: Design Mode or Tunnel Test Mode. In the Design Mode, you can change design variables including the flight conditions, the engine size, the inlet performance, the turbo machinery compressor and turbine performance, the combustors or burner performance, or th
This is is a primer on scientific efforts to understand the origin, evolution, and fate of the universe. Among the questions it explores: What types of matter and energy fill the universe? What is the age and shape of the universe? How rapidly is it expanding? The website examines the Big Bang theory, as well as tests and limitations of the theory.

Stereographic Projection of Crystal Faces
This site features a lecture by Dr. Stephen Nelson from Tulane University that explores a systematic way to define crystallographic angles. The lecture discusses crystallographic angles and gives an introduction to the use of stereographic projections for depicting the angular relationships between crystal faces. Scientific illustrations clarify the text.
This site provides animations, images, interactive maps and videos that can be used to teach about the concept of geologic time. Visual resources cover some specific topics of earth history including plate tectonics, continental drift, relative age dating and paleontology. These resources are appropriate for an introductory level geology course.
This site features a collection of visual resources that can be used to help illustrate the process of physical weathering. Visualizations demonstrate different styles of mechanical weathering and the resulting impact on the landscape. Resources include animations, interactive graphics and photographs showing the effects of physical weathering. These visualizations are suitable for use in an introductory level geology lecture, lab, or other activity.

At a Crossroads: The King of Prussia Inn
recounts the history of this inn, built originally as a farmhouse in 1719 at an intersection of two roads northwest of Philadelphia, not far from Valley Forge. The inn provided hospitality to travelers when the colony was just a scattering of farms. In part because of its location, it became a prosperous tavern, inn, and social center for the evolving community of the same name.
