Subjects: Chemistry and Physics |

In this set of three activities, students will learn about electrochemistry. In the first activity they will build a Volta Pile – a simple battery. This invention marked the beginning of electrochemistry. Students will then study electrolysis. Electrolysis uses electric current to split water into its components: hydrogen and oxygen. These products can be used as propellants for spacecraft and/or to provide oxygen to support a crew. In the last activity, students examine and use a fuel cell.
