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 past and present, and learn how science and technology
link together in developing
safe and efficient designs that meet human needs.
Focusing Questions: How do structures stand up under a load?
What forces act on structures,
and what materials and design characteristics contribute to their strength and stability?
Key Concepts
STS and Knowledge Outcomes
Students will:Describe and interpret different types of structures encountered
in everyday objects, buildings, plants and animals; and identify materials from which they are made
Students will:Demonstrate and describe processes
used in developing, evaluating and improving structures that will meet human needs with a margin of safety
