Nano Lens: What Is It Made Of?

About this activity

A clean white nanotech lab in soft blue light. A hovering lens drone dives from everyday samples on their trays (a balloon of air, a spoon of table salt, a gold ring, tap water) down to their particles, then into one particle. Students predict from the outside look, dive in, and sort each sample by what the particles show: pure substance or mixture, then element or compound.
