A new periodic table exhibit was installed on the upper level of Nichols Hall after the 2022-2023 school year’s final exams. The table offers students an opportunity to see physical samples of several elements. Students often gather around the table to observe the elements and visually engage with abstract chemistry concepts.
Over the past summer, upper school chemistry teacher Andrew Irvine collaborated with upper school science department head Anita Chetty and administrators, including upper school division head Paul Barsky and head of school Brian Yager, to install the new periodic table exhibit.
“I love materials, and most chemistry and science teachers [do] too,” Irvine said. “You see a piece of paper as a periodic table, that’s one thing. But if you can see it in real life, it’s [a] different thing.”

The periodic table currently contains physical samples of about 100 elements. For elements which are physically unprocurable, upper school science teacher and department head Anita Chetty notes that scientists that are named after the elements are showcased instead.
“You’ll see there are some elements which we don’t have a sample of because they only exist in nuclear reactors or in laboratory conditions for very brief periods of time,” Chetty said. “We’re highlighting or showcasing the scientist it was named after, but we can’t actually get the element. It’s not available in its pure form on the planet.”
According to Chetty, the exhibit took approximately four months to construct. Chetty also noted that chemistry was the only major scientific field without an exhibit in Nichols Hall, which motivated the department to create one. For instance, the Foucault pendulum in the Nichols Rotunda acts as a physics display, and both the saltwater reef aquarium and the freshwater tanks serve as biology exhibits.

“We’ve been trying to make the building a place that invites students to come and learn more than what we’re teaching them in the classroom,” Chetty said. “We want to extend the learning, [and] we want to find things that are more interactive.”
To install the periodic table, the department had to find a reasonably priced vendor for installation, run electricity through the concrete wall and install LED lights in the exhibit with a circuit that would light up each box in the periodic table display.
“I looked and found a local plastic fabricator, and I didn’t know there was anything like that, but I found one,” Irvine said. “There was one from the East Bay called Mr. Plastic, and we got a quote that was pretty reasonable. And then [we] went through different designs and [for] several months [we] went back and forth the design process, and they put together this wonderful display.”

To further the educational benefits of the exhibition, the department plans to create a QR code for the periodic table so students can learn more about the elements while looking at them.
Chemistry student Koby Yu (10) believes that seeing the elements of the periodic table in person can motivate students to explore chemistry further.
“[I] thought [the installation of the periodic table] was awesome,” Koby said. “Taking chemistry, it was interesting to see all the elements that we’ve only ever heard about. I’ve never actually seen them, so it’s interesting to put a face to the name.”
