Digital Library for Earth System Education (DLESE)
(26.580 recursos)
The Digital Library for Earth System Education (DLESE) is a grassroots, community-based effort involving teachers, students, and scientists working together to create a library of educational resources and services to support Earth system science education. DLESE supports Earth system science education by providing access to high-quality collections of educational resources; access to Earth data sets and imagery; support services to help educators and learners effectively create, use, and share educational resources; and communication networks to facilitate interactions and collaborations across all dimensions of Earth system education.

Optional Soil Infiltration Protocol - The GLOBE Program, University Corporation for Atmospheric Research (UCAR)
The purpose of this resource is to determine the rate at which water soaks into the ground. Students place two cans into the soil and add water to them to a depth of at least 5 cm. Students measure and record the time it takes the water level to drop a fixed 2 - 4 cm distance. Students repeat the measurement to determine how easily water moves vertically through the soil. Educational levels: Primary elementary, Intermediate elementary, Middle school, High school

Soil: The Great Decomposer - The GLOBE Program, University Corporation for Atmospheric Research (UCAR)
The purpose of this resource is to understand that soil, under different environmental conditions, plays a role in the decomposition of organic materials. Students use bottle experiments to observe changes in the decomposition of vegetable scraps. Students vary temperature, moisture, and light conditions to determine the conditions that best facilitate the decomposition of organic material in soil. Educational levels: Primary elementary, Intermediate elementary, Middle school, High school

Digital Multi-Day Soil Temperature Protocols - Introduction - The GLOBE Program, University Corporation for Atmospheric Research (UCAR)
The purpose of this resource is to introduct details on how to use digital soil thermometers. A digital thermometer is used to measure current temperatures as well as daily minimum and maximum temperatures. One temperature probe is placed at a depth of 5 cm in the soil while another is installed at a 50 cm depth. The daily minimum and maximum temperatures are stored by the instrument for a period of up to six days and need to be read and recorded at least this often to avoid loss of data. Educational levels: Primary elementary, Intermediate elementary, Middle school, High...

Automated Soil and Air Temperature Monitoring Protocol - The GLOBE Program, University Corporation for Atmospheric Research (UCAR)
The purpose of this resource is to continuously measure soil and air temperature at one site. Students install four temperature probes; three are placed in the soil at three different depths and one is placed in an instrument shelter. Students use a data logger to record readings from the probes every 15 minutes. Students transfer the data to their school computers for analysis and submission to the GLOBE database. Educational levels: Primary elementary, Intermediate elementary, Middle school, High school

Digital Multi-Day Max/Min/Current Air and Soil Temperatures Protocol - The GLOBE Program, University Corporation for Atmospheric Research (UCAR)
The purpose of this resource is to record daily measurements of maximum, minimum, and current air and soil temperatures at a common site. One temperature probe is placed inside the instrument shelter while another is installed at a 10 cm depth in the soil. A digital thermometer is used to measure current temperatures as well as daily minimum and maximum temperatures. The daily minimum and maximum temperatures are stored by the instrument for a period of six days and need to be read and recorded within this span of time. Educational levels: Primary elementary, Intermediate elementary, Middle school, High school

The Data Game - The GLOBE Program, University Corporation for Atmospheric Research (UCAR)
The purpose of this resource is to learn how to estimate data results in order to minimize errors in reading or recording data. Students participate in a game in which they collect data using various instruments and calculations and then try to fool other data collection teams by exaggerating some of the data numbers. They do this activity first with data describing objects in the classroom, then with soil moisture measurements, and then with other GLOBE data. Educational levels: Primary elementary, Intermediate elementary, Middle school, High school

Bulk Density Protocol - The GLOBE Program, University Corporation for Atmospheric Research (UCAR)
The purpose of this resource is to measure the bulk density of each horizon in a soil profile. In the field, students collect three soil samples from each horizon in a soil profile using a container with a measured volume. In the classroom, students weigh the samples, dry them, and weigh them again to determine their dry mass and water content. Students then sieve the dry soil samples and measure the mass and volume of any rocks and material with dimensions greater than 2 mm. Students use the Bulk Density Data Sheet to calculate the soil bulk density for each...

Soil and My Backyard - The GLOBE Program, University Corporation for Atmospheric Research (UCAR)
The purpose of this resource is to explore soil and soil properties. Students discover the variability of soils, derive relationships among soils and the soil forming factors, and link the GLOBE Soil Investigation to the students. local environment. Students use soil samples from their homes to identify properties that characterize their soils. They compare and contrast their soils to those of their classmates. As a class, students describe relationships between the properties of their soils and how and where they were sampled. Older students construct a soil classification schema. Educational levels: Primary elementary, Intermediate elementary, Middle school, High school

Soil Characterization Protocol - The GLOBE Program, University Corporation for Atmospheric Research (UCAR)
The purpose of this resource is to characterize the physical and chemical properties for each horizon in a soil profile. Students identify the horizons of a soil profile at a soil characterization site, then measure and record the top and bottom depth for each horizon. For each horizon, students describe the structure, color, consistence, texture, and abundance of roots, rocks, and carbonates. Samples are collected and prepared for additional laboratory analysis.
