Building Flood-Proof Structures

Third-graders explored the science behind natural disasters through an exciting STEM challenge—designing flood-proof structures. The project began with students analyzing the problem of flooding and discussing how engineers protect buildings in flood-prone areas. Working in small teams, students brainstormed possible solutions and formulated their ideas.

Using simple materials like tinfoil, straws, and waterproof tape, they built creative prototypes. Next, they tested their structures by simulating flood conditions, observing how well their designs held up against rising water. When some models sank or leaked, students adjusted their designs—adding stronger supports or sealing gaps to improve water resistance.

Through this hands-on experience, students learned to think like engineers—evaluating, testing, and improving their ideas. The activity encouraged collaboration, problem-solving, and perseverance while connecting classroom learning to real-world environmental challenges.
