In this field activity, students learn about the five soil-forming factors and their influence on soil properties such as moisture, temperature, color and texture. They identify factors such as slope, shade, plants and compaction, and investigate... (View More)

Students determine the moisture content of a sponge after squeezing the water out of the sponge, and allowing water to evaporate from the sponge. Students also measure the amount of water that has evaporated from the soil samples. This learning... (View More)

In this hands-on activity, students conduct bottle experiments to learn about the conditions that best facilitate the decomposition of organic material in soil. In the lab, they observe changes in the decomposition of vegetable scraps by varying the... (View More)

In this virtual lab experience, learners simulate measuring soil moisture and soil bulk density following the GLOBE protocol for NASA's SMAP (Soil Moisture Active Passive) Earth satellite mission. This resource is part of GLOBE Pedosphere (soil)... (View More)

Students will time the flow of water through soils with different properties and measure the amount of water held in these soils. They will also experiment with the filtering ability of soils by testing the pH of the water before and after it passes... (View More)

To determine if data values are reasonable, students need to understand the units of measurement and be able to estimate the expected range of values in data. This activity has groups of students collecting and recording data, changing some of the... (View More)

In this activity, participants learn about the geosphere by making observations and taking measurements. They will go outside and use scientific equipment to investigate water in the soil by measuring soil moisture, temperature, color and... (View More)

The pedosphere (soil) is the focus of this GLOBE eTraining program module. Protocols for investigating soil temperature, moisture, characterization, density and infiltration are explained. In addition, each module includes interactive digital field... (View More)

These two posters represent visual data collected from satellites, ground based observations, and model predictions representing solar energy, average temperature, cloud cover, precipitation, soil moisture and vegetation over 12 month periods in... (View More)
