Use the case of the Kursk submarine to devise an experimental investigation into catalysts’ effects on rate of reaction in this lesson plan for 14–16 year olds.

In this lesson, students plan an investigation into the effect of catalysts on the rate of a reaction, particularly in the decomposition of hydrogen peroxide. The activity is placed in the context of finding out what sank the Russian nuclear submarine Kursk, and begins with stimulus material in the form of a text document and a teacher demonstration.

After checking and evaluating their experimental plan students carry out practical work, share results and agree on conclusions. Finally, they work in groups to extract information from unfamiliar but contemporary texts.
