Out of the Lab and into the Stream
On the morning of October 2, seventh graders headed out of the science lab and into the waters of the Gwynn Falls stream on McDonogh's campus to collect all sorts of information. The annual outing is the culmination of a science unit on the physical and chemical properties of water. Working in small groups, students measured water velocity, depth, width, and temperature at various locations along the stream.
The young scientists also collected bugs and identified them. “This is particularly useful data because some of the organisms are very sensitive to water quality,” explained science teacher Eileen Heady. "The seventh grade is happy to report that the sensitive bugs are thriving."
Unfortunately, the students shared one disturbing observation. "We noticed increased levels of ersosion due to high levels of rainfall in the spring and ever increasing development in the area," explained Heady.
Over all, it was a very successful adventure. In addition to returning with lots of useful data, the students brought back many bags of trash. "Thanks to their efforts the stream is cleaner than ever," said Heady.
