We had a science expo in our school. The topic of the project assigned this time was "Metals are good conductors of electricity". To present this, I used a small heavy battery, a small bulb and small wires...
I connected one end of each wire to the screws on the base of the light bulb holder. Free end of one wire to the negative ("-") end of the battery and the other wire to the positive ("+") end of the battery are also connected. As battery is an electrochemical cell, it act as energy source. The bulb lights up because the conductor completes the circuit and electricity flows from the battery to the bulb and back to the battery.
As wires are made up of metals, electrons flows across the metal from one wire to the other. Thus we can conclude that, metallic wire completed the circuit, the bulb lights up and hence are conductors, which conduct electricity....
Though this is the simple experiment, I enjoyed thoroughly...my friend Harshada explained her part i.e., "metals are conductors of heat". We did explain other metal properties like lustrous, ductility, malleability and sonorus with examples...

Looking forward to share few more, as and when I find interesting things...
