In this activity, students learn about the biological and physical conditions that lead to eutrophication of a water system by using real-time data to predict the the growth of harmful algae. They also conduct research on the Internet to learn more... (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)

In this activity, students view a satellite image of Earth at night, and consider the environmental considerations and consequences associated with the pattern of light they see. The resource includes a map for student use. Summary background... (View More)

Students are presented with a graph of atmospheric becomes CO² values from Mauna Loa Observatory, and are asked to explore the data by creating a trend line using the linear equation, and then use the equation to predict future becomes CO² levels.... (View More)

Each student will explore three activities that promote understanding of and respect for soil. They will generate responses to the following questions: "What makes up soil?" and "What lives in the soil?" Next the students will watch a demonstration... (View More)

The purpose of this investigation is to understand the change that takes place when water condenses from a gas to a liquid, and how a change in pressure affects this transformation. Materials needed for the experiment include a large (2L) soda... (View More)

In this activity, students monitor the change that takes place when water vapor condenses from a gas to a liquid and see how a change in temperature affects this transformation. Materials needed to conduct the investigation include two thermometers,... (View More)

This experimental activity is designed to develop a basic understanding of the interrelationship between temperature and pressure and the structure of a device made to examine this relationship. Resources needed to conduct this activity include two... (View More)

In this activity, students examine a pair of satellite images of the ocean and determine whether there is a relationship between the height of ocean waves and the sea level. Data from the two images are plotted side by side and students discuss the... (View More)
