Welcome to the fascinating world of two-dimensional (2D) materials! Today, we're going to explore a novel 2D material created by boiling off atoms, which we guide to form large crystalline flakes that will become the filling in tiny magnetic sandwiches. Intrigued? Click to learn more!
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!
The term may be unfamiliar, but we all have a sense for viscosity. We often think of it colloquially as the “thickness” of a fluid. It’s the property that makes honey pour so differently from water. Fluid dynamicists – scientists and engineers who study how liquids and gases move – tend to think of viscosity in terms of a fluid’s resistance to flowing or changing its shape.
