A "pencil lead" is a mixture of the graphite allotrope of carbon mixed with clay and baked hard.
While a pencil lead will conduct electricity, it can not be used to make a light bulb.

What element element is in the carbon family often mistaken for the end of your pencil?
Pencils use Graphite, not lead. Graphite is made of carbon, and no one mistakes a pencil of having carbon. They may mistake it of having lead, in which it is corrected that pencils no longer use lead-but instead use Graphite, which is made of carbon. It is not often mistaken that a pencil is made of carbon. Because it is made of carbon, so how you can make a mistake by thinking the pencil is made of graphite? Its true, not a mistake. This riddle is probably backwards? Or its just a trick question, I dont even know.
How much energy does a normal light-bulb make in comparison to a colored one?
They are the same light bulb, so they are the same. The colored bulb has coloring applies on its outside surface. They do not make energy, they use energy.

How do you make a homemade rheostat?
use a small battery, nine volt or six...make sure you have the proper bulb for the max. voltage. Split a common pencil to expose the grafite core. One wire taped to the exposed end of the pencil and to the battery. To the other post of the battery connect a second lead. By sliding the second lead back and forth on the surface of the pencil the bulb will grow brighter and dimmer based on proximity to the other lead (taped to the end of the pencil)...or replace the pencil with an old door spring. It will work in a similar fashion. Low voltage, no danger, good presentation of electrical resistance. Appropriate for middle school students to do.
