After being inspired by visual artist  Olafur Eliasson  Lower School science teacher Sheri Cocquio had a vision for a project with the first-grade class.  She approached Lower School music teacher Peter Musselman and Lower School art teacher Peggy Schauffler to see if they would join her in a world of light and shadow.  For this 7th episode in the "Collaboration Series," Rob sits down with these three teachers to hear about the project,  how they worked together and what they uncovered along the way.
