SF-M1 | Cross-Cutting Concepts
Complex and microscopic structures and systems can be visualized, modeled, and used to describe how their function depends on the shapes, composition, and relationships among its parts, therefore complex natural structures/systems can be analyzed to determine how they function.

Electric Crystals: Exploring how crystal symmetry can power everyday life
Crystals aren't magic, but they are amazing! In this student-driven, lecture-free lesson, students will do card sorts, build hands-on models, solve engineering design puzzles, and more! The whole experience is connected through a beautifully crafted comic and supporting videos.

Lessons: 2, 3, 4
Molecular and geometric models of the unit cells are used to demonstrate the function and structure of the macroscopic crystal. Specifically, molecular models of quartz and table salt demonstrate the effects of (a)symmetry on the electrical properties of the bulk crystal, namely piezoelectricity.
