Conductivity: Pure Water + NaCl
In these short videos, Dr. David Hobbs demonstrates the conductive properties of water. Conductivity refers to the amount of dissolved solids present in an aqueous solution, allowing it to conduct electricity. In this first video, Dr. Hobbs observes changes in conductivity when salt (sodium chloride, NaCl) is added to pure, or deionized, water. Right-click or […]

Measuring the Landscape
We are going to use Google Earth to look at Montana landscapes from above. Before going further, you may want to review some examples of different landforms (landform examples are available in several different formats – they all include the same examples): Landform Examples Web Format (can also be accessed using the dropdown menu at […]
