Learning science involves learning important concepts, conducting experiments to see first-hand how researchers discovered and confirmed some elements of science concepts, and learning how to think scientifically. With this complete approach to learning science, students are well-prepared to deal with the natural world around them and to make wise decisions when confronted with various choices....

Observations of daily precipitation have been a part of GLOBE from the beginning. At the start, GLOBE’s participation model was that schools would take measurement following all of the original 17 protocols. Atmosphere temperature, precipitation, cloud, and soil moisture measurements were to be collected daily at a site easily accessible to the school. A permanent installation of an instrument...

From the start, the measurement of daily maximum and minimum air temperature within one hour of local solar noon has been a key GLOBE protocol. The low cost approach was to use a U-tube thermometer housed in a wooden instrument shelter facing away from the equator. The U-shaped tube contained mercury with pins on either side of the mercury. As the air temperature warmed the pin on one side...

As Earth science has a single uncontrolled object of study, the first rule is to take today’s data today. While ice and sediment cores and fossils can reveal past conditions, the observations that can be made right now cannot be replaced by ones taken later. This goes well with the Native American adage, “You can’t step in the same river twice.” The environment is constantly changing and doing...

Consider the rain gauge used in GLOBE, CoCoRaHS, and other citizen science programs. Just four pieces plus 2 mounting screws – an inner graduated cylinder, an outer cylinder, a cap/funnel, and a mounting bracket. The area of the outer tube is exactly 10 times the areas of the inner tube and the cap/funnel, so the graduations on the inner cylinder can be spaced ten times further apart. Thus, 0.2...
