Seventh Graders Analyze Rock Creek

Partnered with EarthForce, an environmental education program, and Cedarbrook Middle School for the sixth year to implement a WWMD event. Eight classes of seventh grade students from Cedarbrook Middle School collected and monitored four samples per class from Rock Creek, a suburban stream running through moderate urban and commercial development in Cheltenham, Pennsylvania. Additional samples were collected for the analyses of phosphate and nitrate, and a more quantitative method was implemented for turbidity. Kick nets were used to collect macroinvertebrates in the stream substrate.
