While competing in a game show called 'The greatest science investigator of all time', famous scientists from history describe their life's work and explain why they deserve the title. On this show it's the turn of Edward Jenner, who tells the story of how he discovered the smallpox vaccine.
After viewing the clip, the class could work together to devise a short play about the life of Edward Jenner. As well as scripting and performing, members of the class could use a range of information sources to flesh out the account of Jenner's life given in the clip. Other children might write a commentary, explaining the significance of Jenner's discoveries and how they still affect they way we live now. The class could perform their play in a school assembly.
