An interactive guessing game featuring nature’s most unusual adaptations and characteristics

Can you tell the difference between a rock, a plant, and an animal? While it might sound simple, the vast diversity of life on earth can throw us some serious curveballs! Sometimes, what looks like a plant is actually an animal. Other times, what looks like an animal is actually a plant! Even things that look like living creatures can turn out to be unique rocks.

Young readers are encouraged to challenge their pre-existing ideas about the natural world in this engaging nonfiction book set up as a scientific guessing game, filled with lively illustrations and fun facts.

Each spread features a realistic illustration of either a puzzling critter, a perplexing plant, or a special stone. Every picture is accompanied by a simple prompt: rock, plant, or animal? The answer is revealed by turning the page to discover a beautifully detailed scene and a brief description of the “species.” Even for the most esteemed naturalists, the answers are hard to believe! Rock? Plant? Animal? lets its readers be detectives, encouraging curiosity and embracing surprise.
