The Orange Juice Clock Kit

What makes this clock run? Why chemistry, of course! Students assemble a galvanic cell and use it to power this 24-hour clock, complete with elements representing hours by their atomic numbers. In addition to learning the atomic numbers of the first 24 elements, students ask and investigate questions. How does the clock work? Can other electrolytes and electrodes be used? How long will the clock run?

The perfect inquiry or scientific method demonstration activity, this complete kit includes instructions and everything needed to power the clock. Size, 24 x 24 x 2".
