Science Infographic – The chemistry of seasonal leaf colours: Why do leaves change colour in autumn and turn green again in spring and summer?

14 September 2017

To help you understand the science behind the forest’s seasonal colour changes, Forestry Commission England has put together a simple colour guide and the chemistry behind it.

Classroom applications: Applicable to a number of year levels and subject areas including:

Foundation – Earth and space sciences: Daily and seasonal changes in our environment affect everyday life (ACSSU004)

Year 1: Earth and space sciences: Observable changes occur in the sky and landscape (ACSSU019) and Biological Science: Living things have a variety of external features (ACSSU017)

Year 2 - Biological Sciences: Living things grow, change and have offspring similar to themselves (ACSSU030)

Year 3 - Biological Sciences: Living things can be grouped on the basis of observable features and can be distinguished from non-living things (ACSSU044)

Year 4 – Biological Science: Living things depend on each other and the environment to survive (ACSSU073)

Year 5 – Biological Science: Living things have structural features and adaptations that help them to survive in their environment (ACSSU043)

Year 6 – Biological Science: The growth and survival of living things are affected by physical conditions of their environment (ACSSU094)

Year 8 – Chemical Sciences: Chemical change involves substances reacting to form new substances (ACSSU225)

Year 9 – Chemical Sciences: Chemical reactions involve rearranging atoms to form new substances; during a chemical reaction mass is not created or destroyed (ACSSU178)
