This element, assigned atomic mass unit of 12.000, is the standard from which all others are measured
Coal & diamonds both consist of it
This element has two crystalline allotropes: diamond & graphite
Like diamond & graphite, fullerene is a form of this element

Until the photocopier, we always had stained fingers from the paper named for this element...& we liked it!
As a diamond, this element melts at about 6500 degrees F.; as graphite, it changes directly to a gas
(Sarah of the Clue Crew shows a slice of bread toasted to golden brown.) Toasting bread is actually a chemical reaction where this element, from the Latin for "charcoal", is released from the starch & sugar during the heating process
By definition, steel is an alloy of iron & this element
Diamond, the hardest known substance, is made of crystallized atoms of this element
To make a diamond, apply a lot of pressure to this element--a lot of pressure!

Organic chemistry specializes in compounds that contain this element
C4 plants, which photosynthesize molecules having 1 more of these atoms than C3 plants, do better if it's hot & dry
(Sarah of the Clue Crew reports from the Argonne National Laboratory in Chicago, IL.) The Argonne National Laboratory dynamometer can measure both a car's particulate production & its fuel efficiency--the latter by simulating road stresses & measuring the products of this element in the engine's emissions
It's No. 6 on the periodic table
A granular activated version of this element is used in filters for gas masks & fish tanks
(Jon of the Clue Crew holds a bicycle frame at Trek Bicycle Corporation in Waterloo, WI.) Trek uses a proprietary method of optimum compaction & low void to maximize strength & minimize weight of frames & parts made of this element
(Alex reports from a swordsmith shop in Tokyo, Japan.) The sword maker must be careful to get the proper amount of this element in his steel to ensure proper hardness; too much of it, however, & the sword becomes brittle
