Recently, Carley Smith, the Rio Blanco County 4-H program coordinator, visited Kay Bivens’ elementary library class in Meeker to demonstrate STEM activities to first- through fifth-grade students as well as discuss 4-H.
Bivens and Smith presented each class with a series of seven different experiments using dry ice, including dry ice safety and the interesting science behind dry ice. The most popular experiment included floating bubbles, where dry ice is dropped into an aquarium with an inch of warm water. As the carbon dioxide builds up, bubbles blown into the aquarium floated in mid-air! The kids learned that the mixture of carbon dioxide and water was heavier in the surrounding air, allowing the bubble to float in the tank.
