Instructional Ideas

  • Using dry ice is a great way to approach science 
  • Conduct and share investigations with groups, and make a list of vocabulary learned
  • Bring in Jello to make with the class in order to discuss and demonstrate how the state of matter changes from liquid to solid
Classroom Considerations

  • Science equipment will be needed
  • Dry ice needed for this activity. Obtain as close to the time being used as possible
  • Safety precautions need to be in place and goggles worn at all times
Pros

  • Challenging and creative way to teach states of matter
  • Resource includes step-by-step guide with three-page PowerPoint and worksheet
  • Definitely an experience that grasps students' attention 
Cons

  • Preparation time needed and storage of dry ice if experiment not completed in single day
  • Use of alcohol, dry ice, and candles might not be allowed in certain learning communities
