The Teacher’s Guide and the new sphere pages build on the approach that examines Earth as the atmosphere, hydrosphere, biosphere, and pedosphere. The study of Earth System Science focuses on the cycles that connect the spheres – the Energy, Water, and Biogeochemical. The Honor Roll provides...

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...

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...
