Kids’ Night at the Observatory: Extending the Centennial Celebration to people of all ages

Wow, did we have fun.

Our history-themed kids’ night at the Van Vleck was a great success! Luckily for the historians in the bunch, no one really asked for explanations of cosmic rays or black holes, but Roy probably could’ve answered anyway. In any case, we had two activities planned, each demonstrating a different facet of the history of the Van Vleck Observatory. The first activity sought to teach about the teaching of astronomy over time and the second activity involved some mystical musical creations.

The first activity, which took place upstairs in the classroom, involved a history lesson on how astronomy lessons used to go. Roy brought out the lantern slide projector and explained that before the advent of photography, astronomers would take detailed sketches of their observations and use delicately-painted glass slides as teaching tools. Of course this meant hauling the Van Vleck’s very own lantern projector and slides out of their current resting place in the preliminary mock-up of the Under CT Skies exhibit in the library. And of course Roy gave a demonstration of the lantern slide, showing off cool plates, painted, photographed, and otherwise.

While showing some lantern slides with images of Mars, Roy touched on one rather silly chapter in history. Back in the late 19th century, after viewing some fuzzy images of the Red Planet and being victim to a miscommunication or two, one American astronomer theorized that Mars hosted an intelligent-life civilization that had built a complex network of water-carrying canals. The theory has since been decidedly debunked.

After Roy showed off some cool slides with the projector himself, we invited everyone to make their own old-timey astronomy teaching materials! We substituted glass plates for plastic transparencies and oil paints for sharpies. With the aid of a cranky overhead projector, and then the actual lantern projector itself (with transparencies cut-to-size), we displayed everyone’s work on the big screen.

Next activity: Down in the basement, Melissa and I (Abby) were stationed with another pack of sharpies, another bunch of transparencies–primed with blank musical staffs, a stack of star charts, and a portable mini-keyboard dating back to the 80’s that Amrys generously provided. After telling the story of John Cage at the Van Vleck, we invited everyone to channel their own experimental music composer.

The story goes that Cage, while a fellow at Wesleyan, wandered up one day to the Van Vleck Observatory and took out Atlas Eclipticalis from the library to use in one of his compositions. Essentially, his method was to draw musical staffs on tracing paper on top of the different star charts and wherever the stars fell on the staffs, a musical note was inferred. So, in the basement during Kids’ Night, we asked people to make their own musical compositions with the stars as a guide, and I would play the compositions when they were complete.

Each composition, all designed with great care by our tiny John Cages, were completely unique and completely compelling. The room would hush the second I started to play; everyone wanted to hear the kids’ handiwork and the universe’s musings! Some people included time and key signatures, others just drew lines “connecting the dots.” I tried to be as faithful to what was written as possible. I also really enjoyed the titles of many of the compositions, such as “Symphony of the Stars” and “Not my fault.”

All in all, history-themed Kids’ Night was a lot of fun! Hope you can make it to the next one!
