Sublimation Bubbles

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form. Participants use water to observe dry ice sublimating into gaseous carbon dioxide, and then capture the gas in soapy bubbles, which are safe to observe and play with. Activity includes a facilitation guide with potential misconceptions, Earth & space science infosheets with real-world connections, table sign, and activity & content training videos. All public-facing materials also available in Spanish.
