This activity is designed to help building student understanding of how scientific theories can change over time. Science theories change in the face of new evidence. However, when new explanatory frameworks, or theories, are proposed to explain scientific phenomena, there is often a lengthy period during which groups of scientists use different competing theories to explain the same phenomena. During the activity, students are introduced to the geocentric and heliocentric models, students compare the two models, and then observe the time it took to change the theory underpinning the heliocentric model. This activity is part of the "Swift: Eyes through Time" collection that is available on the Teacher's Domain website.

In this experiment, students create a "lava lamp" - a beaker on a hotplate, and investigate buoyancy, convection and other fluid and thermodynamic properties using ink, water, vegetable oil and Alka-Seltzer tablets.

NASA scientist, Neil Gehrels, serves as your guide to this online lesson on gamma ray tools, which focuses on advances in detector technologies since the 1980s that have enabled us to capture and image high-energy phenomena. Dr. Gehrels explains different methods for detecting and imaging high-energy particles, how they work, and the advantages and disadvantages of each, using examples and imagery from NASA missions.

Vortices of water, called "eddies," form off the northwestern coast of North America in the winter, and are particularly large during El Nino winters. Users can read and view satellite imagery which explains how these eddies carry nutrient-rich water offshore, providing nourishment for phytoplankton, microscopic plants which form the foundation of the marine food chain. This is part of NASA's Earth Observatory, a collection of publications featuring satellite imagery and information about Earth.

This lesson applies the science and math of the rotation of a sphere to water and wind movements on Earth. Students are introduced to convection, the Trade Winds and the Coriolis Force. Using an online visualizer, students generate trajectories and then analyze course patterns and latitudinal changes in strength. Note that this is lesson two of five on the Ocean Motion website. Each lesson investigates ocean surface circulation using satellite and model data and can be done independently. See Related URL's for links to the Ocean Motion Website that provide science background information, data resources, teacher material, student guides and a lesson matrix.

In this problem-based learning activity, students will examine opposing views on the Amazon Rainforest and will take a position on land-use and species conservation in one of the last areas of biodiversity on Earth. This activity is part of Exploring the Environment.

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 instructions on the program operation. The linked pages will take a little longer to load into your browser. If you follow the instructions given below, you can download a copy of each program to your computer and you can then run the programs off-line.

This is a set of three, one-page problems about the sizes of moons in the solar system. Learners will use decimals to compare the sizes and distances of Saturn's moons to the center of Saturn. Options are presented so that students may learn about the Cassini mission through a NASA press release or by viewing a NASA eClips video [4 min.] about these and other moons in our solar system. This activity is part of the Space Math multi-media modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school.
