Unit

Electric Crystals: Exploring how crystal symmetry can power everyday life

Grades

7-12

Electric Crystals unit banner

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.

Alignment summary( Target)

Lessons: 2, 3

Students create molecular models of crystal unit cells, as well as geometric models of unit cells. They interpret how the two types of representations have different benefits and uses, and when each representation might be useful.
