Oceans play a significant role in determining and moderating the effects of energy imbalances. Students will begin this lesson by working with temperature data to reinforce the importance of protocols, practice computing statistical measures of data... (View More)

This is a hands-on lab activity about seawater density. After developing a hypothesis, learners will conduct a simple investigation of density. They will discuss changes in density observed and describe how salt affects the density of water.... (View More)

This is a hands-on lab activity about the composition of salt. Learners will explain the general relationship between an element's Periodic Table Group Number and its tendency to gain or lose electron(s), and explain the difference between molecular... (View More)

This is a hands-on lab activity about seawater density, specifically the relationship between density of fluid, weight of an object, and buoyancy. Learners will develop hypotheses and observe a demonstration of density to understand its role in... (View More)

These two hands-on labs are about the role of temperature and salinity in governing the density of seawater, a major factor controlling the ocean's vertical movements and layered circulation. In the first activity students work in groups to... (View More)

Student teams explore atmospheric aerosols, dust, and fires and their impact on the Earth's albedo using NASA Earth Observations (NEO) website. This is an extension activity in the student learning activity guide accompanying the GLOBE Earth System... (View More)

In this activity, student teams explore connections between parts of the Earth system, by examining a time series of environmental data maps. Each team examines a single variable displayed on a global data map, and identify the unit of measure, the... (View More)

In this activity, student teams conduct a quantitative exploration of the connections between parts of the Earth system, through examination of a time series of environmental data maps. By investigating the connections between environmental data,... (View More)

In this learning activity, students compare changes in insolation with changes in surface temperature in the polar regions using scientific visualizations of global data sets. Links to readings related to the shrinking ice cap and albedo are... (View More)

In this learning activity, students compare polar data from the Arctic and Antarctic, explore Earth’s albedo and its effect on arctic sea ice, and examine graphed data and scientific visualizations of remotely-sensed satellite data. Readings... (View More)
