This is a PowerPoint lesson (guidelines included on the slide notes) which can be used to set up a fun revision lesson/final lesson for exam classes. In this lesson, students have to answer a series of clues/questions linked to A-level biology to get the code to a padlock to win the contents of a locked box!

P.S. This lesson also has a version for GCSE level teachers! Please refer to my Biology Resources web page to view that version.
