Two University of Washington, Bothell professors will participate in the upcoming Paws on Science event April 9-11 at the Pacific Science Center in Seattle.

Professor, Science and Technology Program Director and Chancellor Emeritus Warren Buck will host an exhibit about the connection between the smallest objects with the largest ones — the sub atomic particles and the stars.

Professor Dan Jaffe will present posters of his world-renowned air-pollution research. He will also display a unique experimental device, built and tested by UW-Bothell freshman Kevin Call, which demonstrates the greenhouse effect.

Paws on Science is open to the public.
