Riko & Tara: Sink or Float?
Will a leaf float? Will a stone sink? Riko and Tara make careful guesses, test a leaf, stone, wooden block, spoon, cork, and other safe objects in a shallow water tray, then sort what they notice. This hands-on preschool science adventure builds prediction, observation, comparison, and early vocabulary while keeping the message simple: a careful guess can lead to a wonderful discovery. Perfect for ages 2–5, pond themes, and screen-free learning with adult supervision.
