7 E/F Math and Science Gators: Unit D: Structures and Forces

Structures and forces are all around us. In this unit we will focus on the following questions:

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

We will look at some of the most impressive structures around the world (both past and present), and then build our own unique structures...

- Modes of failure

- Performance requirements

I can classify structural forms and give examples.

I can describe structures that share a common design.

I can compare structures developed by different cultures at different times.

I can use units of force and mass

I can identify tension, compression, shearing and bending forces

I can describe how forces can cause failure
