Clay is a term used to describe a group of hydrous aluminum phyllosilicate (phyllosilicates being a subgroup of silicate minerals) minerals , that are typically less than 2 μm (micrometres) in diameter. Clay consists of a variety of phyllosilicate minerals rich in silicon and aluminum oxides and hydroxides which include variable amounts of structural water. Clays are generally formed by the chemical weathering of silicate-bearing rocks by carbonic acid but some are formed by hydrothermal activity. Clays are distinguished from other small particles present in soils such as silt by their small size, flake or layered shape, affinity for water and tendency toward high plasticity.
Pinching is when you get a piece of clay and circle it and put your thumb in the middle like it your were making a thumbot and go round the edges and pulling and pinching out and up. you can also make them flat.
you take a piece of clay and use it on a bucket of water, voila, soft clay.
If clay is a rock
A clay tablet is a flat piece of clay that was used in ancient times as a medium for writing. Scribes would inscribe symbols or text onto the soft clay using a stylus, often for record-keeping, literature, or administrative purposes. Once the writing was complete, the tablet could be dried or baked to preserve the information. Clay tablets are particularly associated with ancient Mesopotamian cultures, where they played a crucial role in the development of written language.
a physical change....? hope that helped a little.
A slab of clay is a flat piece of clay rolled out. With a slab of clay, it is much easier to cut/trace things.

A flat piece of wood is called a board.
you take a piece of clay and use it on a bucket of water, voila, soft clay.
Water deposits the clay particles in thin, flat layers.
You have made a physical change to the clay.
The key signature of a piece written in F flat major has six flats: B flat, E flat, A flat, D flat, G flat, and C flat.
If clay is a rock
The clay boat (like a steel ship) displaces its own weight in the water. So, as long as the sides of the clay boat (or steel ship) is above the water level, it will float. A solid piece of clay will (like a stone) sink immediately.
It depends on how long you strecth it because clay an be rolled up to i think i foot!
