FEATURES

A radio astronomy system for observing the sun
Jeffrey M. Lichtman

This project was conceived while I was studying astronomy in the 1970s at Suffolk Community College and the Vanderbilt Planetarium.

For a semester project, I thought of correlating visual solar events with the associated radio components. This would be an easy project, since there was a lot of data on solar events. Thus, the sun would be an easy object to study. More.

Dig into the GLOBE Soil Moisture Campaign
Martha P. L. Whitaker,
GLOBE Soil Moisture Research Scientist
The University of Arizona

Soil moisture content is an incredibly important aspect of natural science. It is critical to plants, it determines how soils absorb water that can cause flooding, and it can even affect local weather patterns by helping keep the soil cool. More.


PRODUCTS

The Sun and Sky Monitoring Station by Forrest M. Mims III.

An excellent product for beginning scientists, seasoned amateurs (or even professionals) looking for a new challenge, or someone trying to come up with a reasonably self-contained science fair project. Briefly stated, this kit gives one the instrumentation needed to track accurately the total sunlight in a given time period, measure haze and water vapor in the atmosphere.
