    Challenge Students To Dive Into This Game Of Skill And Science

    Hook™ is based on a game dating back to the 15th century. An updated version of the classic Cartesian Diver science experiment, named after Rene Descartes, it challenges your students to explore air pressure and density as they try to get the A hook" diver to latch onto the A sinker" diver inside a plastic bottle of water. They do this by squeezing the bottle and manipulating the floating diver's buoyancy. Plastic soda bottle required (not included).

    Standards Match
    We Know Standards

    In the U.S alone, nearly 30% of educational standards are overhauled, revised or edited each year. Tracking these changes demands the full-time expertise and we have the tool to manage those standards, so you can trust us as the leader in standards alignment. Correlations are made for all State, National, and Common Core Standards. In addition, we have Head Start standards for early childhood. And most recently, we’ve added both National STEM Standards and Next Generation Science Standards (NGSS).
