Hydrogen-Oxygen Reaction Lab

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates then determine which ratio produces the most energy and draw conclusions to their hypotheses.

Instructional Ideas

  • Teach a lesson prior to this activity on balancing chemical equations
  • Remove the hypotheses from the worksheet and have the teams come up with their own
Classroom Considerations

  • Hydrogen and oxygen need to be created and held in gas bags, or hydrogen and oxygen generators need to be built prior to instruction
  • Everybody needs to have goggles and gloves
Pros

  • Lab activity shows the concept learned in balancing equations
  • Background information provides a reason to look at the reaction between hydrogen and oxygen
Cons

  • None
