Surface Area - Cart Demo

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio. Learners learn that smaller particles have a much higher proportion of atoms on the surface. Learners unfold paper cubes, drop alka-seltzer in water, turn potatoes black with iodine, and observe fireballs to understand how surface area changes as things get small. Safety note: this demonstration involves...
