Students install soil moisture sensors and temperature probes and connect them to a Davis Soil Moisture and Temperature Station. Data are logged every 15 minutes and periodically students transfer these data to a computer and report them to GLOBE.

Students log atmosphere data using a Davis automated weather station. A weather station is setup to measure and record atmospheric measurements at 15 minute intervals. These measurements are transferred to your school's computer and then submitted to GLOBE via email data entry.
Students use a digital multi-day maximum/minimum thermometer mounted in their instrument shelter to measure the maximum and minimum air and soil temperatures for up to six previous 24-hour periods.
Students will use a digital multi-day maximum/minimum thermometer mounted in their instrument shelter to measure the maximum and minimum air and soil temperatures for up to six previous 24-hour periods.
Students will use a second digital multi-day maximum/minimum thermometer mounted in their instrument shelter to measure the maximum and minimum soil temperatures at 5 cm and 50 cm depths for up to six previous 24-hour periods.
GLOBE schools participating in the Earth Networks Schools Program arrange for their data to be transferred automatically to GLOBE. A special GLOBE Atmosphere Study Site is defined for the school's Earth Networks weather station, and this activates an automatic transfer of their Earth Networks data to the GLOBE database.
Students will use four temperature probes and a data logger to measure air temperature and soil temperatures at depths of 5 cm, 10 cm, and 50 cm every 15 minutes.
Measure the current air temperature when an instrument shelter is not available. Current air temperature is measured using a thermometer held in the open air but in the shade for at least 3 minutes.
Students log atmosphere data using a RainWise automated weather station. A weather station is setup to measure and record atmospheric measurements at 15 minute intervals. These measurements are transferred to your school's computer and then submitted to GLOBE via email data entry.
Students will use a technique chosen by their teacher to expose a soil profile for characterization.
Students log atmosphere data using a WeatherHawk automated weather station. A weather station is setup to measure and record atmospheric measurements at 15 minute intervals. These measurements are transferred to your school's computer and then submitted to GLOBE via email data entry.

Activities to help students learn more about the instruments and protocols

Students discover that soil properties such as moisture and temperature can vary considerably across a single landscape.
Students make mud pies by adding water to the various soil components, letting them dry and observing the pie's characteristics.
Students are introduced to the basic concepts of how water passes through soil in an activity which illustrates the scientific method. More advanced students investigate the effects of soil characteristics on water infiltration and the chemistry of water that has passed through soil
Beginning students are introduced to the basic concepts of how water passes through soil in an activity which illustrates the scientific method. More advanced students investigate the effects of soil characteristics on water infiltration and the chemistry of water that has passed through soil
Students collect, describe and compare soils from their own backyards.
Students will understand the geologic phenomena of weathering and erosion. These processes, along with deposition, shape our landforms and contribute to the development of parent material in the soil formation process.
Students simulate environmental conditions in order to determine the key factors that affect the decomposition of organic material in soil.
Students explore soil moisture by weighing and drying sponges and then they explore their soil samples in the same way.
Teams of students play a game in which they gather data and distort the values of certain measurements. They then estimate the values of the measurements taken by other teams and try to detect their errors.
An activity which highlights the importance of learning about the soils on Earth. In this activity students explore some of the many uses of soils, learn the five soil-forming factors, and gain a better understanding of how little of Earth's surface is covered in soil.
