Sink or Float Engineering Challenge | Boat Building STEM Activity for K–2

Created by

Can you take something that sinks and make it float? Part of a 20-challenge series, this exciting engineering challenge, students explore buoyancy and design by reshaping materials (like aluminum foil or clay) to build a boat that stays on top of the water. Children connect their work to real-world engineering by learning how boat designers create vessels that float. Includes an introductory page with a real-world connection to ship engineering, step-by-step instructions with a materials list, a
