Ferroelectric materials generate electric fields that move charges around, just as a bar magnet produces a magnetic field that moves magnets around. Ferroelectric materials can be used for data storage to make electronics more energy efficient, but they don’t always play well with the silicon technology used in devices like phones and computers.

Students learn how some crystals produce electricity when squeezed! This lesson is part 4 of a 4-part student-driven, lecture-free series, in which students will do card sorts, build hands-on models, solve engineering design puzzles, and more!
Students make paper models of crystal unit cells and build a large crystal structure together while reflecting on the role of symmetry in crystal formation. This lesson is part 3 of a 4-part student-driven, lecture-free series, in which students will do card sorts, build hands-on models, solve engineering design puzzles, and more!
Crystals aren't magic, but they are amazing! In this engaging, comic-driven lesson, students do individual and group-based activities to understand the characteristics of crystals (like quartz) versus amorphous solids (like glass). This lesson is part 1 of a 4-part student-driven, lecture-free series in which students will do card sorts, build hands-on models, solve engineering design puzzles, and more!
Through hands-on activities using gumdrops and toothpicks, students will learn about unit cells that make up the repeating structures of crystals like table salt. This lesson is part 2 of a 4-part student-driven, lecture-free series, in which students will do card sorts, build hands-on models, solve engineering design puzzles, and more!
