This kit allows students to explore the electrical properties of different combinations of electrode materials using safe, everyday chemicals such as soda, vinegar, and fruit juice as electrolytes. The set contains everything needed for the experiments except the electrolytes. Voltage, current, and polarization effects can be investigated. Contents of the set include a simple cell with electrode holders, electrodes of copper, aluminum, iron, and zinc, a mounted resistor for use as a current load, a multimeter, and a manual.

Students will enjoy connecting batteries, wires and bulbs in various combinations to try to make bulbs light. Snap-on wire clips enable students to make connections between the batteries and bulbs quickly. A chart of various arrangements for connecting the batteries and bulbs is provided. The student studies the chart, predicts which arrangement will light the bulb and which will not, then connects the real batteries and bulbs (following the diagrams) to prove or disprove original predictions. Purchase size "D" batteries separately.
