Today, we went over the structure of the light  bulb.  Describe how the filament supports are arranged in the "thread" part of the bulb.  Why is this arrangement important to where the bulb has to be touched?  Be careful to answer both parts of the question.

Today went really well.  I must say I was concerned with letting go of the "rules" and having you students use your mobile devices to post.  Terrific job! 

The best answer to the questions is something along the lines of "The arrangement pictured will not light because the bulb is not receiving current to its bottom."  You could also have added that this arrangement is much like numbers 7 and 9 that did not light when you tested them.  This would be your evidence.  So, new question, WHY DOES both the bottom and side of the bulb have to be touched in that arrangement?

Electricity: It is more than it seems

We started out today looking at this image and predicting which situations would light the bulb.  After testing in class, comment below your findings.  Be prepared to discuss your reasons if and when you are asked.

 In the drawing, we have a battery with a bare wire running from the negative pole of the battery to the positive pole of the battery.  The bare wire is then touching the threads of the bulb.  So, what do you think, will it light?  Why or why not?

Our first article we will read, summarize and answer a question about is located at this link:
