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."

Students explore volcanoes.  In this deep sea volcano lesson students complete a worksheet and various activities.

Young scholars 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.

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 compare and contrast Archaea with bacteria and other organisms.  In this ocean instructional activity students complete diagrams.

This multi-media site is packed with interesting information about the exploration of the undersea volcanos situated along the Marianna Arc.
