Ask each student to select a tree for himself and observe it carefully. The students should draw an outline of the shape of the tree to mark what they see on it.
They should note down whatever life they are able to see on or around that tree. They should note down the details like: what types of birds, insects and other animals did they see on the tree and where? How many were there? Did they notice any nest? What were the birds, animals, insects doing?
The students may go for observation more than once to notice the patterns of life on and around the trees. They should then return and present their drawings to the class. Which kinds of trees have a greater variety of life on them and why?
VARIATION / EXTENSION
Discuss the possible relationships these life forms have with one another and with the tree. Draw lines connecting the things which are inter-related.
