PROBLEM: Can electrical circuits be used to gain information?

PREDICTION:

PROCEDURE:

Holding the cardboard lengthwise, attach 5 paper clips about an inch apart along the left side. Then attach 5 paper clips to the right side in a direct line with the corresponding paper clips on the left. Number the clips 1-10, as in the diagram. Follow the "circuit" diagram below.

Using alligator clips, attach one clip to the paper clip on the question side and then one on the answer side. Devise 5 questions and their answers. Record them below. Put the questions and answers on the appropriate "circuit" so the bulb will light when the correct circuit is completed.

Circuit Diagram (example)

Have another set of partners take a "quiz" on your circuit board.

What happens when they get the correct answer?

Why does this happen?

CONCLUSIONS: How does a quiz board illustrate how electricity can help gain knowledge?
