Learn about the GLOBE Program student investigations that explore the Earth’s hydrosphere - the water component of our planet, including liquid water, ice and vapor. Changing any part of the Earth system, such as the amount or type of vegetation... (View More) in a region or from natural land cover to an impervious one, can affect the rest of the system, and water plays a role in many of these changes. Rain and snow capture aerosols from the air. Acidic water slowly dissolves rocks, placing dissolved solids in water. Dissolved or suspended impurities determine water's chemical composition. Water is a good solvent and participates in many of the chemical reactions that take place in the Earth system. Water provides a habitat for mosquito larvae. GLOBE eTraining provides the opportunity for new and existing GLOBE users to complete science protocol training online and consists of downloadable training modules, interactive digital field and lab experiences, and online assessments for each module. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)
Learn about the GLOBE Program student investigations that explore soil. Soil is the great integrator storing and affecting the chemistry of water, storing and releasing heat at Earth’s surface, retaining the effects of past climate and other... (View More) forces of soil formation, while providing the medium for virtually all plant growth on land. Soil moisture and temperature can change rapidly while soil characteristics typically persist for a century or longer. The soil measurements collected by GLOBE cover the full range of properties. Students and scientists investigate the pedosphere – the global layers of soil – through collection of data that are generally unavailable from any other sources and address the significant local variations in soils. GLOBE eTraining provides the opportunity for new and existing GLOBE users to complete science protocol training online and consists of downloadable training modules, interactive digital field and lab experiences, and online assessments for each module. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)
Students are tasked with virtually designing a spacecraft to withstand the harsh environment of the Van Allen Radiation belts- the location of many communication, GPS and weather satellites. The details of the challenge, along with videos on... (View More) radiation, a materials list (including descriptions, densities, costs, and testing), and subsystems information are included.

This short video (~2 minutes) explains how a raindrop falls through the atmosphere and why a more accurate look at raindrops can improve estimates of global precipitation. This information is important to scientists working on the Global... (View More) Precipitation Measurement (GPM) mission - understanding the micro world of raindrops provides insight to scientists about the macro world of storms. (View Less)
This collection of activities is based on a weekly series of space science mathematics problems distributed during the 2012-2013 school year. They were intended for students looking for additional challenges in the math and physical science... (View More) curriculum in grades 5 through 12. The problems were created to be authentic glimpses of modern science and engineering issues, often involving actual research data. The problems were designed to be one-pagers with a Teacher’s Guide and Answer Key as a second page. (View Less)
In this activity, participants learn about the hydrosphere by making observations and taking measurements. They will go outside and use scientific equipment to investigate temperature, pH and transparency of a body of water. They will use this... (View More) qualitative and quantitative data to understand why it is important to know about the condition of freshwater sources in many places in the natural environment and how these places are connected in the water cycle. Data collection is based on protocols from The GLOBE Program. This activity uses the 5E instructional model and is part of the "Survivor Earth" series of one-hour lessons. (View Less)
In this interactive, manipulate the future sources and sinks of carbon to estimate the atmospheric CO2 levels and global temperatures in the future. This is part of Unit 3 of Interactives and Models: Carbon in the Future & You.
Using global data sets with monthly resolution, you will adjust variables in this empirical climate model to test the degree to which natural and human influences can account for observed global temperatures from 1979-2010. This is part of Unit 3 of... (View More) Interactives and Models: Carbon in the Future & You. (View Less)
This interactive model lets you manipulate and work to balance the biologic (e.g., photosynthesis, respiration) and human processes that replicate the observed CO2 record from Mauna Loa. This is part of Unit 2 of Interactives and Models: Carbon Now.
