Is nature symmetrical?
The Basic Idea
Sort them in to different categories according to apparent symmetry Check symmetrical accuracy by laying them on to a grid, comparing one side to another
NB: Be very careful of children picking random leaves. Some plants are poisonous. Children should wear gloves if you are unsure and wash hands after the activity.
How to take it even further or make it more challenging
Pose the statement: Nature is not symmetrical. Challenge children to find examples of natural environments that prove and disprove this statement. Encourage the children to look very closely, such as the tip of a leaf.
