In this activity, learners explore sublimation by capturing carbon dioxide gas in soapy bubbles sublimated from dry ice.
“Sublimation Bubbles” shows how some solid materials can sublimate directly into their gaseous form. Participants use water to observe dry ice sublimating into gaseous carbon dioxide, and then capture the gas in soapy bubbles.
BIG IDEA
Chemistry can help us understand our world and learn about how materials behave and change.
Chemists use tools to discover and make new things.
LEARNING GOALS
- Learners will develop positive attitudes toward learning about chemistry:
- Learners will increase their feelings of interest in chemistry through hands-on exploration and observation of chemistry concepts and phenomena.
- Learners will increase their sense of self-efficacy related to chemistry through hands-on interaction with exciting materials, and by successfully understanding how to do the activity.
