How to Get Students Thinking and Acting Like Scientists

(even in large classes):

Bead Salinity Demonstration

A Professional Development Workshop Presented By :

Dr. Andrew C. Muller

Concepts in salinity are often difficult for students to conceptualize, especially the abstract nature of concentration in parts per thousand or even parts per million.  These two activities focus on multiple properties of ocean salinity, allowing the student to both visualize the salt content and act as a scientist in discovering some interesting ocean salt properties.



The first activity is called Bead Salinity using a visual way to understand concentration.  The second activity is a mock cruise to sample the ions in seawater to discover the concept of constant proportions in the ocean.
 
The workshop will be held
November 24, 2003 from 4:00-5:30
Room 102 of Brossman Hall
