On Saturday, October 8, more than 1,500 visitors of all ages came out to Open House at Columbia Climate School’s Lamont-Doherty Earth Observatory. There, they played with glacial goo, watched trash cans erupt with water and ping pong balls, and performed hands-on science experiments — all while learning about how Lamont researchers help us to better understand our planet, from the bottom of the ocean to the top of the atmosphere. Below are a few highlights from the 2022 Open House.

A balloon popping underwater shows how hydrophones record sounds under water. (Watch the computer screen to see the sound levels spike.) By emitting sound waves toward the ocean floor, and measuring how they get reflected, scientists at Lamont are able to explore what the seafloor looks like, and peer at the rock layers beneath.

Each line in this piece, created by the Tempestry Project, represents one year of temperature data starting in the year 1 AD. Notice how rapidly things heat up as we get closer to modern times. Beads near the bottom mark every 50 years. Video: Sarah Fecht
Selecting strings of different colors, visitors made their own temperature reconstructions (see below). Photo: Sarah Fecht

I wouldn’t be surprised if I were told that 20 thousand attended @LamontEarth and @columbiaclimate LDEO Open House where they witnessed swimming plankton, exploding volcanoes, hear seismic sounds, learn how trees tell stories and and so much more. pic.twitter.com/4GaFGLRbI5
