Construct a simple conductivity tester as per the diagram below. Determine the conductivity of various metal and non-metal objects by performing the following steps:

a. Put a flashlight bulb in a socket and mount them onto a piece of wood.

---

b. Connect one wire from the socket to one terminal of the battery.

---

c. Connect another wire lo the other side of the socket (NOT to the battery).

---

d. Connect a third wire to the other battery terminal (NOT to the socket).

---

e. Wrap (at least six times) each of the loose wire ends to clean head thumbtacks.

---

f. Place the tacks (after wire wrapping) firmly into the erasers of two pencils that are used as the conductivity probes.

---

g. Now that you have constructed a conductivity tester (a simple conductivity analyzer), test a variety of objects and record the results in chart form.
