8. One day, while watching the chimpanzees, Jane Goodall saw something peculiar. She watched as a chimpanzee looked into a hollow in a tree. The chimp picked off a handful of leaves from the tree and chewed on them. Then the chimp took the leaves out of its mouth and pushed the leaves into the tree hollow. When the chimp pulled the leaves back out, Jane saw the leaves sparkled with a gleam of water. The chimp then put the leaves back in its mouth. What was the chimp doing? How did Jane think through this experience?
