Activity 1
Which can Conduct Electricity, Metals or Nonmetals?
Objective
In this activity, you should be able to distinguish between metals and
nonmetals based on its electrical conductivity.
Materials Needed
samples of copper, aluminum, sulfur, iron and iodine
white paper
improvised conductivity apparatus
Procedure
1. Place a sample in a sheet of white paper. This will help you observe the
samples better. In Table 1, note down the appearance of each of them.
Table 1. Electrical conductivity of different materials
Q1. Which of the samples look like metals? How about nonmetals?
2. Place the end tip of the improvised conductivity apparatus in contact
with each sample. If the tester gives off a sound, the sample is said
to be electrically conductive. Otherwise, it is electrically nonconductive.
Note: Do not let the end tips of the conductivity tester touch each other.
Q2. Which of the samples are electrical conductors? Which are not? Note them
down in Table 1.
