This short video and interactive assessment activity is designed to teach fifth graders about distance between items.

This short video and interactive assessment activity is designed to teach fourth graders about distance between items.

This short video and interactive assessment activity is designed to teach fifth graders about solving multi-step distance problems.

Multi-scale systems differ from traditional macro-scale systems in that the multi-scale systems use components from two or more scales (i.e. nano, micro, meso, and macro-scales). Subject provides the skills required to design and manufacture multi-scale systems. Emphasis is placed on understanding the fundamental differences between traditional macro-scale system design and the design of multi-scale systems. Topics include design methodologies, modeling approaches, analytic tools, and manufacturing processes. Examples drawn from a diverse range of applications, including automobiles, fiber optic equipment, electronic test equipment, and micro/meso-scale machinery. Students master the materials through problem sets and a substantial term project.
