"Up and at 'em!" Wake up and get ready to learn about science in an exciting story about three superheroes with the powers of solids, liquids, and gases! Meet Blockhead, the strong, silent type, with the power to change his body into rocks, metal, or other solids. Catch a wave with Flo, the team's sassy super soaker, who cleans up the streets with the power to become any liquid. Professor Vapor, team leader and science expert, clears the air with his power over gases. The three heroes live with a cute, little girl named Molly Cule, who needs their help on a science report for school. Using models and real-world examples, Molly teaches her class about how the atoms are arranged in solids, liquids, and gases. In a fun and informative way, the students learn how evaporation changes a liquid to a gas, as well as other scientific concepts.
