December 11, 2008 - Cambridge Polymer Employee Teaches Kids About Polymers on PBS
Ayyana Chakravartula, a former Cambridge Polymer scientist, was featured on an episode of the PBS children's show, Fetch with Ruff Ruffman. In this episode, two of the children on the show are tasked with creating a new plastic toy. Dr. Chakravartula explains the properties of polymers using chains of paper clips, and describes different types of polymers we come in contact with everyday. She also describes the properties of viscoelasticity by stretching and snapping putty, and by making a mixture of cornstarch and water.

This eisode (Season 3, Number 18: Just Toying with Ruff Ruffman) was filmed in 2007 and was recently aired. Click on the info link below to view a short clip.

February 1, 2008 - CPG Hosts Job Shadow Day for Brighton High School Students
CPG participated in Boston Private Industry Council’s Job Shadow Day on February 1, 2008. Three Brighton High School students were invited to spend the day with CPG researchers.

Job Shadow Day allows students to visit a worksite and “shadow” our employees for several hours, observing and assisting them with their work. This structured worksite experience provides students with a preview of the world of work and the range of career opportunities available to them. Job shadowing is integral to making the connection between school and work.
