"Exploring Fabrication - Electroplating" is a hands on activity in which visitors coat a nickel coin with copper using the electroplating process. They learn that electroplating can deposit nanometer-thin layers of materials.

In this activity, learners make a voltaic pile, the first kind of battery. The activity is designed to prompt conversation and reflection about responsible innovation, inspired by themes raised in Mary Shelley’s novel Frankenstein.

Students will create thin layers of copper and nickel in an electrochemical reaction to understand how an electric current passed through an ionic solution will result in a chemical reaction which will separate materials. In addition students will also explore...

The corral is an artificial structure created from 48 iron atoms (the sharp peaks) on a copper surface. The wave patterns in this scanning tunneling microscope image are formed by copper electrons confined by the iron atoms. Don Eigler and...
