Answer 1

Experiment

Aim - rate of conduction of heat is different for different materials.

MATERIALS AND APPARATUS:

Bunsen burner

Vaseline

copper, iron, brass and aluminium rod

stopwatch

drawing pins

tripod

cardboard or paper

matches

METHOD:

Stick the flat end of a drawing pin to the end of each of the metal rods using the Vaseline. Try to use the same amount of Vaseline for each drawing pin.

Place the cardboard on the tripod.

Balance the metal rods on the cardboard so that one end of each is over the Bunsen burner.

Light the Bunsen burner.

Using a stopwatch, measure how long it takes for each of the pins to drop off.

Record your results in the table.

Draw a bar graph to illustrate your results.
