Piner High School on Thursday night is holding its monthly science lecture series open to the community.

This time, Sonoma State Chemistry Professor Steve Farmer will present about fluorescence.

The series, named after the science, technology, engineering and math disciplines, is called STEM Cafe and takes place in Piner’s new, state-of-the art planetarium and science center called SPARQ. The school tested out the lecture series last fall and found it so popular they decided to continue on a regular basis this year, said science teacher Judy Barcelon.

Students, teachers, parents and community members are all invited to attend, Barcelon said.

The evening starts with a 7 p.m. lecture, is followed by a coffee and snack break, and ends with an interactive lab or activity, which in this case will revolve around fluorescence.

The SPARQ Center is located on Piner High School’s campus, 1700 Fulton Road. More information on the program is available at http://pinerhighstemcafe.weebly.com.
