A wonderfully written non-technical introduction to antimatter, as well as a brief discussion of the investigation into the asymmetry between the quantities of matter and antimatter observed in our universe.
A portal to resources on the sun, the Earth's neighboring planets, and the weather in space. Find out why Saturn is the "jewel of the Solar System" and explore what happens when Venus and Mercury make their rare transits across the sun.
Researchers share their observances from the McMurdo facility in Antarctica through webcasts and field notes. Two interactives are included in the collection.
Make a scale model of the Solar System and learn the REAL definition of "space." You tell it how large to make the sun (in inches or millimeters) and the page will do all of the calculations for your scale model solar system and provide other scaled data. Requires JavaScript capable browser. Links to a more detailed page that calculates sizes and distances for moons also.

A resource rich is scientific research investigating the origins of matter. Find strategic locations of observatories, the scientists conducting the research, tools used to study the world, and how the ideas of one scientist might impact the studies of another. Experience virtually live opportunities to see the studies conducted first hand.
Over 30 simple, interactive, experiments can be found on the Exploratorium site. This museum, based out of San Francisco, presents each experiment with a list of materials, a short procedure, and the scientific reasoning behind the experiment.
Here is a monumental list of ideas for science fair projects and experiments, organized alphabetically. Every one of them is a link to a full page, with pictures, of information about the idea. This site is a goldmine.
This site from The Exploratorium Museum is a full description of a short activity. An electrophorus plate and a Leyden jar are made. The electrophorus is charged by induction. Its charge is transferred to the Leyden jar by conduction several times until a large charge is stored in the jar. The charge is then discharged, creating a (very bearable) shock.
