Making a Quiz Board (continued)
- When you make sure that you have connected the paper clips correctly, tape the second poice of cardboard to the back of the quiz board to protect the wiring.
- To make your tester, first use a piece of wire to connect one side of the light-bulb holder to the negative end of the dry cell. Then connect a piece of wire to the positive end of the dry-cell holder, as shown below.
- To use the tester, have a friend touch the end of one wire to a paper clip next to a question. Your friend should then touch the other wire to the paper clip next to the answer he or she chooses. If your friend has answered the question correctly, the bulb will light.
