Important Message about LEARN NC

LEARN NC is evaluating its role in the current online education environment as it relates directly to the mission of UNC-Chapel Hill School of Education (UNC-CH SOE). We plan to look at our ability to facilitate the transmission of the best research coming out of UNC-CH SOE and other campus partners to support classroom teachers across North Carolina. We will begin by evaluating our existing faculty and student involvement with various NC public schools to determine what might be useful to share with you.

Don’t worry! The lesson plans, articles, and textbooks you use and love aren’t going away. They are simply being moved into the new LEARN NC Digital Archive. While we are moving away from a focus on publishing, we know it’s important that educators have access to these kinds of resources. These resources will be preserved on our website for the foreseeable future. That said, we’re directing our resources into our newest efforts, so we won’t be adding to the archive or updating its contents. This means that as the North Carolina Standard Course of Study changes in the future, we won’t be re-aligning resources. Our full-text and tag searches should make it possible for you to find exactly what you need, regardless of standards alignment.

chemical composition n.
The chemical elements that a substance is made or composed of; for example, salt has a chemical composition (or is composed) of sodium and chlorine.
clay n.
A sedimentary material with grains smaller than 0.004 millimeters in diameter.
commercial adj.
Of or relating to the buying and selling of goods, especially on a large scale, as between cities or nations.
deposition n.
The natural process of laying down a deposit of something.
earthenware n.
Pottery made from a porous clay that is fired at relatively low temperatures.
environment n.
The area in which something exists or lives.

Any clay formed in place by the chemical and physical weathering of rock.
pulverize v.
To pound, crush, or grind to a powder or dust.
pyrometric cone n.
A cone used to measure heat during the firing of ceramic materials in a kiln. The cones, often used in sets of three, are positioned in a kiln with the items to be fired and provide a visual indication of when the items have reached a required state of maturity, a combination of time and temperature.
reconstitute v.
To bring (a liquid in concentrated or powder form) to normal strength by adding water.
recrystallize v.
To crystallize, or cause to form crystals or assume a crystalline structure, again or repeatedly.
remnant n.

secondary clay n.
Any clay deposited in secondary locations, usually by erosion or the flow of streams, away from where it was formed.
sediment n.
Solid fragments of inorganic or organic material that come from the weathering of rock and are carried and deposited by wind, water, or ice. Sediments may also be formed from chemical, biochemical, or biological materials. [more]
sedimentary adj.
Of or relating to rocks formed by the deposition of sediment. [more]
stoneware n.
