Autumn around the world is a time that lends itself to investigate leaves, through making leaf art, going on a leaf scavenger hunt and learning about trees and their leaves.
Yet in New Zealand where almost every native tree is evergreen, the emphasis on trees changing colour and losing they leaves could seem to favour introduced trees over native trees. Here are some activities and ideas for studying native tree leaves in New Zealand. Autumn is still a good time to study leaves as it is interesting to compare deciduous and evergreen trees.
ACTIVITY: Go on a leaf hunt to find different colour leaves and identify whether trees are evergreen or deciduous.
Deciduous trees - those that lose their leaves in autumn - do so to survive a cold winter, saving energy and getting rid of leaves that might pick up diseases. The trees draw back into their branches and trunk all the goodness that was in the leaves, such as water, nutrients and the green substance chlorophyll. So the leaves change colour, dry out and fall.
