This activity is a short engineering design challenge to be completed by individual students or small teams. A real-world problem is presented, designing buildings for hurricane-prone areas, but in a simulated way that works in a classroom, after... (View More) school club, or informal education setting. Students are given simple materials and design requirements, and must plan and build a tower as tall as possible that will hold up a tennis ball while resisting the force of wind from a fan. After the towers are built, the group comes together to test them. If there is time after testing, which can be observational or framed as a contest between teams, students can redesign their towers to improve their performance, or simply discuss what worked well and what didn’t in their designs.
