2. Steps for the Teacher to do  Make 2 versions of the picture but put the faulty bulb in one of the circuits

3. Overview  In life, people face problems that need to be solved.  Sometimes the problem may be how to construct something new.  It may be finding out how to fix something that isn’t working.  Whatever the problem, there are certain strategies that can make the job of problem solving easier.  In this lesson, a step-by-step problem solving technique will be developed that you can use to test electric circuits.

4. Materials  Box with battery, 2 wires, bulb, battery holder, and bulb socket  Another 6 inch wire per student  Activity Sheet 3 per student  Troubleshooting with Circuits Sheet per student  6 pieces of wire for the teacher  2 battery holders with batteries for the teacher  1 faulty bulb in a socket for the teacher  1 bulb in a socket for the teacher

5. Troubleshooting Techniques  Problem Solving Strategies  Practice isolating the problem and figuring out how to fix it  Things to try before you have to ask someone for help

6. Activity Sheet 3

8.  Connect the wires of the 2 circuits created by the teacher earlier so see the bulb come on  How would you figure out how to make the bulb in the second circuit light?  Make a list of the responses. Label it “troubleshooting strategies.”

10. Troubleshooting Strategies  Wire connection-tightly secure, wiggle gently to check not loose – touch wires to check again  Battery-in holder tight, ends are touching the holder- touch wires to check again  Bulb-securely screwed but not too much-touch wires to check again  Take battery and a different bulb and connect to wire like lesson 2  Take bulb and a different battery and connect to wire like lesson 2

11. Create a testing circuit  Get another 6 inch wire  Draw circuit tester on the board and leave it put together as a model to follow.  Assemble own testing circuit

12. Closing  Disassemble all parts and place them back in your box.  With partner – review the troubleshooting processes learned today  Troubleshooting = technique for solving problems  Can use these techniques whenever equipment is not working properly.  If you find a faulty bulb or battery, bring it to me.

13. Extensions  Place 3 or 4 circuits that have different faults in them such as a loose connection, a burned-out bulb, or a drained battery and figure out what is wrong with the circuit.  Interview parents about problem solving. Ask how they solved a problem around the house or with the car. Write a brief account o the strategy that was used.
