Useful Link

Activity One - Read and Watch

Before we look at how interrelated the different elements of the nexus are we need to understand why being resource secure is such an important issue.

  • Click on the website - www.videonot.es - or search for videonot.es
  • Sign in using your school account using the 'sign-in' button found in the top right hand corner of the screen.
  • Copy and paste the url for the youtube clip below into the URL bar on the left hand side of the page and then press load video.
  • Give your notes a sensible title e.g. 2017 - Year 12 - Nexus - Food
