Curated OER
Rechargeable Ni-Cd Batteries
In this rechargeable batteries learning exercise, students read about how nickel-cadmium batteries work and answer four critical thinking questions about rechargeable batteries, how they work and their benefits.
Curated OER
Answer Key for More Advanced Electrochemistry Calculations
In this electrochemistry activity, students solve 9 problems such as identifying masses of metals produced at cathodes, determining the potential of a cell's electrode and writing cell reactions along with their potential.

Make a Battery From a Lemon
Fifth graders construct a voltaic battery. They change chemical energy into electrical energy by inserting copper wire into a lemon. They discover the tingle of the wire on their tongue is due to the movement of electrons.

Redox and Electrochemistry
In this redox and electrochemistry learning exercise, students identify the anode in electrode pairs of electrochemical cells. They also describe how a lemon battery works and how wet and dry voltaic cells work.
