The word paludarium comes from the Latin word ‘palus’ meaning marsh or swamp and ‘–arium’ meaning enclosed container. How many species did you find in the Paludarium in the museum lobby? Did you see the big angelfish? Were you lucky enough to catch a glimpse of a crab hiding in the moss on the rocks? The Paludarium is a living ecosystem where all of the living elements (mosses, plants, crabs, and fish) and non-living elements (the water, air, and rocks) interact with one another and are linked through nutrient cycles and energy flows. The balance of the ecosystem is supported each day with just a little food for the fish.
Use your cell phone to transform an entire silo into a dazzling light show! Several thousand lights illuminate when you use a mobile phone in the vicinity of the exhibit.
Every single mobile phone transmits radio waves to connect to a cellular network, and every day millions of people around the world broadcast their conversations across these invisible waves. Tiny sensors in this exhibit detect and convert the invisible electromagnetic waves from a cell phone into another frequency, the range of visible light. Thousands of sensors incorporated in the display are tuned to detect the phone’s electromagnetic radiation.
Movement of underground water through big caves and tiny cracks and crevices in rocks is the often invisible part of the water cycle.
