Conduction+in+Action+Lab

**__CONDUCTION IN ACTION LAB __**
__Purpose__: To investigate the rate of cunductivity through different metals. __Procedure__: See page 432 __Materials__: -four 8cm conduction bars (aluminum, zinc, copper, tin, and lead) - felt pen - ruler - candles - matches - stopwatch - graph paper - coloured pens or pencil crayons

__Data__:

__ANALYZE__:

1) You could tell by the waz on the bars

2) a) Almost, some of them took longer than other. b) Tin, coppeer, zinc, lead, aluminum, and carbon

__CONCLUDE AND APPLY__:

1) The particles in the bars barely move, they are solid, but with heat the particles start to move all over the place.

2) Carbon because si the one that took the longest to conduct heat and make the wax melt.

__CONCLUSION__: In the lab I learnt that some metals such as Aluminum are better thermal conductors than metals such as carbon or zinc. Furthermore, I learnt that metals conduct heat and thermal energy at different rates and the difference between thermal conductors and insulators.
