Structures and Mechanisms: Grade 7 - Structural Strength and Stability

1. demonstrate an understanding of the relationship between the effectiveness of structural forms and the forces that act on and within them;
2. design and make a variety of structures, and investigate the relationship between the design and function of these structures and the forces that act on them;
3. demonstrate an understanding of the factors (e.g., availability of resources) that must be considered in the designing and making of products that meet a specific need.
