Investigate how different catalysts affect decomposition of hydrogen peroxide, linking to the Kursk submarine disaster, in this lesson plan for 16–18 year olds

In this session, students explore the story behind the sinking of the Kursk submarine. They respond to text and background information before carrying out an experiment to compare the effects of a range of catalysts on the rate of decomposition of hydrogen peroxide.

The investigation can be planned with different degrees of open-endedness, providing a setting for students develop coherent thinking about experimental design and set up.
