This activity challenges you to collect leaves, nuts, seeds and other objects from the natural world in your discovery bag, and try to identify them by comparing colour, shape and feel.
What objects will you put in your discovery bag?
Try to use objects that have a very distinctive shape or feel, but avoid anything sharp. You could use:
A, B, C, D and E – seeds and nuts
There are many shapes, sizes and textures of seeds and nuts. Avoid those that are sharp or prickly.
F – fruits
Try fruits such as figs, apples and cherries. Make sure they aren't too ripe and soft!
G – leaves
Try to find leaves with varying shapes and colours.
H – lichen
Look for lichens on fallen twigs or pieces of bark that have dropped from the tree.
I – bark
Try finding barks with very different textures.
