This learning activity engages students in measurement of pH in water and soil samples, plants and other natural materials. By mixing different substances, they observe how pH changes, and become familiar with the pH of common household products.... (View More)

In this demonstration, the process of cooling by evaporation is related to the serious health risk of hypothermia. Materials required include a desk fan, thermometer with exposed bulb, cotton or gauze, bowl, and material including cotton and wool.... (View More)

In this inquiry investigation, students explore how light hits things of different shape and form. One real world application to this activity is understanding what we actually observe when we see a solar eclipse. Supplies needed for this lesson... (View More)

In this inquiry investigation, students will learn about how light travels by using mirrors, prisms, and shadow makers. Supplies for this investigation include mirrors, prisms, objects of differing transparency, garden hose or spray bottle,... (View More)

This hands-on activity demonstrates how the combining two fluids (confluence of two rivers, Mediterranean water spilling over the straits of Gibraltar into the Atlantic) involves two processes: (1) stirring - stretching of the bulk fluid, and (2)... (View More)
