Mr. Glenn Lid, a longtime Proviso East High School chemistry teacher who retired in 2014, and Mr. Alexander Aschoff, a current Proviso East chemistry teacher, performed a series of chemistry demonstrations at the National Science Teachers Association (NSTA) National Conference in March at McCormick Place in Chicago.
They were part of the workshop, "Morning of Chemistry: The Best of ChemWest," that featured science teachers from across the Midwest who are part of a networking group, Mr. Aschoff said. Mr. Lid and Mr. Aschoff had been invited by Flinn Scientific, a chemical supplies company, and Mr. Mike Heinz, the science department chair at Downers Grove North High School, to demonstrate scientific principles for students from grades six to 12. The demonstrations included creating a variety of squeezable/sinkable cartesian divers, forming a human "salt" bridge, and a variation on the classic "water to wine" demonstration in which they perform a rap.
Dr. Nettie Collins-Hart, superintendent of Proviso Township High Schools District 209, said that the excellence of the teachers at Proviso East and the rest of District 209 was on display at the conference.
"Our teachers are one reason for our community to take pride in our schools," Dr. Collins-Hart said. "Teaching excellence is a key component to producing successful learners and ensuring that our teachers have the greatest impact in their classrooms, and we appreciate Mr. Lid and Mr. Aschoff having an opportunity to demonstrate a sample of that excellence on a national stage."
