Where There's Smoke, There's ...
A remotely operated vehicle approaching a volcano was engulfed by molten sulfur where the plumes of fluids contained the highest concentrations of aluminum ever recorded. This isn't science fiction or an April fools joke, though it did...

Thermochemical Calculations
Viewers learn where the heat goes when phase changes take place with a presentation that explains the latent heat of phase changes, or, more specifically, the molar heat of fusion, solidification, vaporization, and condensation. The show...

Changes in Matter
Do solids, liquids, and gases even matter? The presentation focuses on changes in matter, including phases, Boyle's Law, Charles' Law, and physical changes.

Energy Works: Yes, Indeed it Does!
Moving from its definition to how it moves and its different types, scholars see different examples and then move into its application and use in everyday lives, in an energy-based presentation.

Density
Change the density of water by adding minerals. The presentation discusses density—from the definition to calculations—and applies it to the real world. It briefly mentions specific gravity, and finishes by showing Archimedes'...

Ocean Layers I
How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

Ocean Layers II
Now that you know the ocean has layers, let's name them. The seventh installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program covers terminology associated with ocean layers, such as thermocline and...

Phase Changes
Examine the energy transfer of phase changes through diagrams. The second slide show in a series of seven presents the information related to energy and phase changes. It includes the effect of pressure on phase changes.
