A toy inventor's new boat designs keep sinking, so students step in as engineers and scientists to solve this buoyancy challenge.
Students explore key concepts like buoyancy, gravity, force, and balance through floating and sinking experiments, investigating how weight and shape affect whether boats stay afloat.
They apply the engineering design process to brainstorm, build, and improve their own floating boat models using everyday materials while tracking data and comparing designs.
The unit culminates with students showcasing their final boats and reflecting on their learning about floating principles and engineering problem-solving.
