Kit includes: 30 alligator clip leads 10 bulbs 6 bulb holders 6 knife switches 6 D-cell battery holders 6 copper electrodes 6 zinc electrodes 6 aluminum electrodes 6 iron electrodes 3 ammeters and 3 voltmeters.

This complete kit allows students to study the properties of electricity firsthand. Students build batteries from different combinations of metals, learn about current and voltage, and use ammeters and voltmeters to measure the properties of the circuits they build.

Students learn the relationship between electrical current, resistance, and voltage and explain their measurements in series and parallel circuits. Instructions included. Materials are sufficient for a class of 24 students.
