The story

A breeze moves the leaves. Sami holds the notebook steady with both hands. Neri shows an enlarged drawing of a flower. ‘Here is the pollen:

very tiny grains. In olive trees, it is mainly the wind that carries them towards other flowers.’ Ada draws a light line between two branches. ‘Like a path in the air?’ ‘We can show it like that in the drawing.’ Leo sees a bee on the low flowers beside the path. ‘Does it have a job too?’ ‘Bees visit many flowers. But for olive trees, we should mainly remember the wind.’ Rumo cannot see those tiny grains flying. He looks at the picture and then at the leafy top.

Some steps need tools and explanations to help us understand them.
