Comment on this resource
Wilson Alwyn Bentley (1865-1931), famous for his photomicrographs of snow crystals, prepared sets of glass lantern slides of dew, frost and ice crystals. Many of these sets found their way to colleges and universities around the United States. The University of Wisconsin's Department of Atmospheric and Oceanic Sciences donated their collection to the Schwerdtfeger Library in 2000. Shortly after, the ... Full description.

This information about the Lunar Prospector mission to the Moon discusses the possibility that ice exists on the lunar surface. The article indicates that no native water ice has been found on the moon. If ice has been found, it most likely originated from meteors and meteorites which periodically bombard the lunar surface.

The purpose of this activity is to measure relative humidity using both a sling psychrometer and a digital hygrometer. Intended outcomes are that students learn to quantify humidity and that there is a limit to the amount of water vapor that the air can hold. Students gain insight into why rain drops and snow flakes form and why there is precipitation. Supporting background materials for both student ... Full description.

The purpose of this resource is to measure the salinity of the water at your hydrology site. Students use a hydrometer to measure the specific gravity of the water sample, and use a thermometer to measure the temperature. With these two values, students will use tables to determine the salinity. Full description.

The purpose of this resource is to log soil data using a Davis soil moisture and temperature station. Soil moisture and temperature sensors are installed at multiple depths and a station is set up to measure and record measurements at 15 minute intervals. These measurements are transferred to your school.s computer and then submitted to GLOBE via email data entry. Gravimetric soil moisture measurements ... Full description.

The purpose of this resource is to sure the distribution of different sizes of soil particles in each horizon of a soil profile. Using dry, sieved soil from a horizon, students mix the soil with water and a dispersing solution to completely separate the particles from each other. Students shake the mixture to fully suspend the soil in the water. The soil particles are then allowed to settle out of ... Full description.

The purpose of this activity is to measure surface temperature with a handheld Infrared Thermometer (IRT). The instrument is pointed at the ground to take surface temperature readings. Intended outcomes are that students will learn to use an infrared thermometer, and understand how different surfaces radiate energy. Supporting background materials for both student and teacher are included. Full description.

The purpose of this activity is to measure the aerosol optical thickness of the atmosphere (how much of the sun's light is scattered or absorbed by particles suspended in the air). Students point a GLOBE sun photometer at the sun and record the largest voltage reading they obtain on a digital voltmeter connected to the photometer. Students observe sky conditions near the sun, perform the Cloud, Optional ... Full description.

The purpose of this activity is to introduce students to the concept of relative air mass and demonstrate how solar elevation angle affects the intensity of sunlight that reaches an observer on the ground. Students work in teams to calculate air mass using simple geometry. Teacher background materials are included. Full description.
