On the way to the park, Paul wants to help Lisa but he is far too small to carry her heavy bag. In the park, they play a game, Lisa lets him touch and guess what she has in her bag. Paul dicovers that everything we use and see, not only has a name, but is different in size, shape and texture too. Lisa''s bag is big and heavy, the skipping rope is long and flexible, the branches on the trees are long and rough, they all have their own special characteristics.
