Activity+10-1B+Conduction+in+Action

=Purpose= To investigate the rate of conductivity through different metals

=Materials=
 * Four 8 cm conduction bars
 * Felt pen
 * Ruler
 * Candles
 * Matches
 * Hot plate
 * Brick or block of wood
 * Stopwatch
 * Graph paper
 * Colored pens or pencil crayons

**Analyze** 1) When I touched a part of the metal bar that was away from the fire under it, it was still very hot. Also, the wax melted without us having to physically move the bar. 2) a) No, some metals like copper didn't conduct well. b)Lead, Tin, Aluminum, zinc,carbon, Copper =Conclude and Apply= 1) The molecules in the bars became heated. As they became heated they traveled at faster rates and created more heat. 2) Copper because it isn't a good conductor of heat so, it wouldn't burn my hand.

In this experiment I learnt that heat can be transferred from one end of a metal strip to the other. It was because of this reason that wax on the opposite end to the fire melted. I also learnt that some metals are good conductors of heat whereas others aren't. I learnt that to stay safe in the kitchen I should know which metals are good conductors of heat or use a wooden spoon to stir.
