A Milton (MA) middle school teacher and
GK-12 WISP Fellow turned to Dr. Bob Chen for
help in designing an environmental sensor system with their 7th grade class. Bob and the
Center for Environmental Sensing Networks (CESN) took on the project, donating their time to help the
7th graders design the sensor system themselves using technology and engineering standards. (See CESN Managing Director
Francesco Peri's story in the video above.) "They figured out what they could measure and wanted to measure," said Bob, "and they
figured out that it should look like a duck so that it wouldn't bother the neighbors".
The CESN staff modified the design a bit, turning the duck into a swan so that all of the
devices would fit.
The swan was
launched using a remote
controlled launching vehicle and it immediately began collecting data, sending it every fifteen minutes to a webpage. "The
students noticed that the water temperature was stratified, so then they could talk about density," said Bob. "Fundamental chemical
processes were observed by watching this continuous record of the swan. It is a very successful use of technology
education that also integrated the students into that process." The swan was also used in the COSEE New England
OSEI.
