Now in paperback! Clarice Bean needs a science project or she's in BIG trouble. Her brother Kurt just wants to save the planet. And now they're both up a tree. "Sometimes I think gravity is a pity," says Clarice Bean, who is learning about planet Earth in school. For a project on the environment, her brain leaps to the holes in the sky from her sister’s hairspray and the nature safari in her brother’s bedroom. But when a big neighborhood tree is about to be chopped to pieces, she has no choice but to join her quirky family in its branches and save the day.
