Making Oxygen and Carbon Dioxide

This Making Oxygen and Carbon Dioxide lesson plan also includes:

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for confirmation. Then, pupils observe and test a chemical reaction to create carbon dioxide by putting out the fire.

Instructional Ideas
  • Due to the safety issues with fire, present as a demonstration rather than as a hands-on activity
  • Create your own questions or homework assignment to support the lesson
Classroom Considerations
  • Carefully follow the clean-up instructions at the end of the demonstrations to prevent unexpected fires
  • Some smoke detectors are more sensitive than others; you might need to notify administrators before completing the experiment
  • Two activities are included and can be completed in one class period.
Pros
  • Discussion points are included with answers
  • Reactions are easily observable
Cons
  • Working with fire makes presents a safety risk
