For this lesson students will explore and compare the physical properties of water and oil. Student sheets are provided in English and in Spanish.

If you look carefully, you could find dozens of similar interesting phenomena that are all linked to the surface tension of water. Here is a project that will help you understand and measure the properties of water surface tension.

Information relating to the properties of water and its behavior.

This investigation will help students understand the physical relationships between natural gas, oil, and water in a reservoir and how these relationships can affect recovery.
