Conduction
Metals Conduct Heat
Metals conduct heat which is why
- A spoon left in a hot drink gets hot taking heat out of the drink
- A poker left in a fire becomes too hot to handle
- We use metallic pans and pots
Metals allow heat energy to pass through them
Metals conduct Electricity
To determine the conducting / insulating property of a list of materials
- Gather up the apparatus you need for this experiment.
- At the end of each metal rod melt on some wax and attach a pin to the wax as it sets (or use vaseline)
- Fill the trough up with hot water
- Start a timer
- Wait and observe which pins fall off and when.
- Note down your observations
- You should be able to rank the various materials as to their heat conduction properties.
- Bring in some material that you want to check its conductivity
- Gather up the apparatus you need for this experiment.
- Connect your crocodile clips to the metal you are testing, observe to see if the light turns on.
- Try this with other materials besides metals too.
- Make up a table of materials and determine if they are conductors or insulators.
