In your village, do the following:
a) Collect different kinds of seeds or hard fruits like nuts.
b) Try to recognise various types of trees, shrubs, herbs, etc. Make lists of plants from different places in the village and of different layers. You may not be able to name all the plants, but it is worth recording and seeing where they grow. Make a record of approximate heights of plants, crown
shape, bark texture, leaf size, and flower colour.
c) Learn to recognise the animal’s droppings.
