The Dropping Pins Experiment

Aim: To Observe conduction along a metal rod.

Equipment: A metal rod, Tripod, Bunsen burner, petroleum jelly, 5-10 drawing pins, a stopwatch.

Method:
1) Set up and light a Bunsen burner.
2) Smear a small amount of petroleum jelly on to the head of each drawing pin.
3) Attach the drawing pins at even intervals along the length of the metal rod.
4) Clamp one end of the metal rod to a tripod.
5) Position the retort stand so the unclamped end of the metal rod is in the Bunsen flame and start the stopwatch.
6)Record the time it takes for each pin drop in the table below.

Observation:
As the heat travelled through the tripods metal leg, the pins started falling off, So the particles that held the pins up melted so then it would fall down.

Pictures will be up soon

Explanation:
It's mostly about the heat travelling up the metal so then whatever's on it would fall down.
