Big idea: Dynamic Earth

The Earth’s crust is constantly changing as new rocks are formed and older rock is worn away.

"Dynamic Earth" is one of 15 big ideas of science in the Best Evidence Science Teaching collection. Understanding of the big idea is built up by a series of key concepts at age 11-16, which have been organised into teaching topics.

The research-informed resources for each key concept make up a progression toolkit that provides:

  • appropriately-sequenced steps for learning progression
  • diagnostic questions to reveal preconceptions and common misunderstandings
  • response activities to challenge misunderstandings and encourage conceptual development

Resources for age 14-16

We are currently looking for sponsors who would be interested in supporting the development of BEST resources for Earth science at age 14-16.
If you would like to find out more, please contact us using the contact details on our BEST Usage Guidelines and FAQs document.

Is there a recommended teaching order?

The Best Evidence Science Teaching resources can be incorporated into your existing scheme of work, if desired. 

However, we have used research evidence on learning pathways and on effective sequencing of ideas to develop maps that suggest how key concepts can be sequenced to build understanding of big ideas of science. These maps can help with curriculum planning.
