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!
Essentially all of our technology is built by manipulating materials on length scales between a tenth of a billionth of a meter (atom-sized) and a thousand meters (skyscraper-sized). We call this range of sizes "funsize."
A bit of stray moisture during an experiment tipped off scientists about the strange behavior of a complex oxide material they were studying—shedding light on its potential for improving chemical sensors, computing and information storage. In the presence of a water molecule on its surface, the layered material emits ultraviolet light from its interior.
Scientists have finally discovered massless particles, and they could revolutionize electronics.
Developing materials that more efficiently convert solar energy to electrical energy is a major research goal of condensed matter physicists. But how do solar panels work?
