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.

In this activity, students identify habitats in Arizona, define and illustrate a food web in a kinesthetic exercise, and explain the importance of biodiversity in a writing assignment. Required materials include a ball of yarn or string. The... (View More) resource includes two student worksheets, a data sheet, answer keys, and Web links. This is Lesson 1 in the unit on Biodiversity, part of IMAGERS, Interactive Media Adventures for Grade School Education using Remote Sensing. The website provides hands-on activities in the classroom supporting the science content in two interactive media books, The Adventures of Echo the Bat and Amelia the Pigeon. (View Less)
