Structures and Forces

Unit Overview:
Structures can be found in both natural and human-constructed environments, serving a variety of purposes and taking a wide range of forms. In learning about structures, students investigate the properties of materials used, and test them under different loads and forces. They examine different ways that structural components are configured, analyze forces involved, and investigate resulting effects on structural strength and stability. As part of their study, students also examine construction methods used in the past and the present, and learn how science and technology link together in developing safe and efficient designs that meet human needs.



  1. How do structures stand up under loads?
  2. What forces act on structures?
  3. What materials and design characteristics contribute to structural strength and stability?
