Haber problems

This lesson has been designed to extend the more able following initial work on the Haber-Bosch process. It begins by viewing the video, which outlines why we need the process, problems associated with it and ways in which researchers at the University of Oxford are working on alternatives.

Students are then placed in role as scientists researching into alternative ways of increasing crop production. They research into how the Haber-Bosch process and the use of the artificial fertilisers have an impact on our environment and why their use is not considered sustainable. They use this information to write a persuasive presentation which they could use to raise funds via a crowd-funding website.

Learning Outcomes

  • Students are able to research into problems associated with the Haber-Bosch process and write a presentation using persuasive language.
