Gain high marks in this very diverse area which though not the most difficult of topics (and with some overlap with geography), is often rushed at the end of year 11, poorly understood or missed out altogether.


By the end of the webinar your students will be able to:

  • Learn how to write balanced compare and contrast answers (so often used to examine this topic) that will score high marks.
  • Understand how to apply understanding of a topic when faced with an ecological problem to produce solutions that consider potential consequences for all of the environment.
  • Know how, why and when to use some of the many methods of quantifying numbers of organisms in nature
