One project during my co-op with the Philadelphia Water Department was to create a PowerPoint for Ellen Freedman Schultz, the Associate Director for Education at the Fairmount Water Works Interpretive Center.  I worked with Ellen to create a presentation for a curriculum project at the Fairmount Water Works. We met and traded feedback multiple times throughout the process in order to get the presentation looking right and convey information well enough.
