Neriah Stephens and Braelyn Benjamin watched in amazement when a piece of dry ice was placed in a cup of water, causing the dry ice (frozen carbon dioxide) to turn into gas and bubble out.

The experiment took place in the ETHOS Science Center’s Science 2 Go Bus, which visited Eastside Connections School in Niles Thursday.

Stephens and Benjamin are in Mrs. Sheeley’s first-grade class, which learned how molecules behave differently at various temperatures.

Science 2 Go is a mobile science laboratory designed for grades kindergarten through eight. It contains six lab stations and some state of the art technology including a computer for each station. The Science 2 Go bus is operated through a joint effort by Elkhart community Schools and the not for profit, ETHOS (Encouraging Technology and Hands On Science).
