Dry ice is a fun way to engage students of all ages and to teach them the principles of chemistry through real life demonstration.  

As dry ice is made from carbon dioxide (CO²), it can be used to learn about this gas which has an important role on our planet.  Here are some fun facts about CO²

  • It is a colourless, odourless gas found in our atmosphere
  • We naturally produce it as we breathe out and on average humans dispel around one kilogram of CO² daily
  • CO² creates fizz in soft drinks
  • Often you will find CO² in fire extinguishers
  • It makes dry ice!

Dry ice can be used in many fun ways to demonstrate different chemical reactions to keep students engaged and hanging out to learn more!

Some examples of what can you do with dry ice in the classroom include:

  • Teach students about sublimation (the process of turning from solid to gas without going through a liquid state) by putting dry ice in liquid. This will give a special fogging effect to a glass of water, but won't make the glass of water overflow as the dry ice 'melts'
  • Show how dry ice can quickly freeze a variety of things, and can even be used to make ice cream!
  • Create foggy gurgling bubbles by mixing dry ice with liquid soap in a container
  • Mixing dry ice with certain foods to create sweet smelling clouds of smoke.
