Explore The Visible Light Spectrum at Crossroads

Whatever the weather, Crossroads at Big Creek will be colorful this week.

The next Science Saturday program will focus on the visible light spectrum. School-aged students and their families may drop by the Collins Learning Center’s lab Feb. 11, 1-4 pm, to try out a variety of hands-on activities, including a make-and-take craft project.

Also set for Feb. 11, 1-4 pm, at the Stonecipher Astronomy Center, 2200 Utah St. in Sturgeon Bay, is the next installment of the Quantum Revolution lecture series. Tom Minahan leads these free lectures, which follow the theoretical and experimental development of quantum physics and the quantum nature of matter and energy. Register at to attend in person, or request a Zoom link to participate virtually by emailing [email protected].

The next meeting of the Door Peninsula Astronomical Society – free and open to the public – will be held Feb. 14, 7 pm, at the Stonecipher Astronomy Center. During “Intro to Spectroscopy: What Kind of Star Do You Think You Are Anyway?,” Jim Gallt will describe an inexpensive method for measuring the wavelengths and colors of starlight to determine star classification and temperature. 

When the Junior Nature Club meets next on Feb. 15, 10 am, preschool-aged children and their companions will go outside to explore the colors in nature. In case of inclement weather, participants will engage in color-related activities in the Collins Learning Center.
