Students discuss the benefits of volcanic activity on marine life. They explain the process of tectonic plates.

Students examine the process of tectonic plates and why the Mariana Arc is active with volcanoes. They create a model of the Mariana Arc out of clay.

Students discover how volcanic processes differ at convergent and divergent tectonic plate boundaries. They identify three geologic features that are associated with most volcanoes on Earth.

Plumb the depths of the Submarine Ring of Fire and explore seismic waves with this lesson. Junior geologists simulate s-waves and p-waves, calculate their speeds, and then apply the data to discover the material that makes up inner...

Read through the extensive background information and then lead your geology or physical oceanography class through an investigation of actual temperature anomaly data from the Juan de Fuca ridge. They translate the data onto a plot,...

Take young scientists into the depths of the world's ocean with the second instructional activity of this three-part earth science series. After first drawing pictures representing how they imagine the bottom of the ocean to appear,...

Learners discover the major characteristics of volcanoes on the Pacific Ring of Fire. They describe the processes that produce the "Submarine Ring of Fire." students explain the factors that contribute to explosive volcanic eruptions.

Young oceanographers study the Submarine Ring of Fire, which is a series of deep-water volcanic vents that come up from the ocean floor. Learners take a close look at the unique ecosystems that are associated with these areas, how these...

Students discover common features of hydrothermal vent fluids. They use this knowledge to locate possible undiscovered hydrothermal vents on the ocean floor.

Students use fundamental relationships between melting points, boiling points, solubility, temperature and pressure to develop explanations.  In this chemistry lesson students complete an activity. 

Students describe the effects of temperature and pressure on solubility of gases and other materials.  In this investigative lesson students read an article and answer questions about it. 

Students interpret phase diagrams and explain the meaning of vocabulary words.  In this ocean explorer lesson plan students describe two uses of super-critical carbon dioxide. 

Students discover the principles of solubility and phase state and their influence on chemical phenomena observed around deep-sea volcanoes. They describe the effect of temperature and pressure on solubility of gasses and solid materials.

Students determine some practical implications of the discovery of liquid carbon dioxide in deep-ocean ecosystems. They interpret phase diagrams and explain the meaning of "critical point" and "triple point."

Young scholars describe chemical changes occurring in hydrothermal circulation systems. They make inferences about the significance of these systems to ocean chemical balance compared to terrestrial runoff.
