Part of Lesson Plan: **Test Lights (updated) by Michael Fleming

Activity Overview / Details

Now go back to the light board.  Add a fuse on the power side. Model exactly how to check the power and ground using a test light. Model it with a good fuse and blown fuse. Discuss what to look for when theire is a bad fuse (power on one side and not the other). Also, if your battery pack has an on/off switch, turn the power off and show what to expect when there is no power (fuse is dead on both sides). Try to have the student lead the discussion, and use their prior knowledge.
