The Mud Beneath Your Feet
Artists in the Schools

The Mud Beneath your Feet: What to do when you find it.

Pinch Pot

1.     Contents
a.     Introduction to clay
b.     Pinch pots
c.     Wrap up
2.     Optional Preliminary Activities
a.     Students explore various soils at school and home to see if there are clay soils in the area.
                                               i.     This can be done as a class activity, or students can be encouraged to bring soil samples from home.
                                             ii.     Using a moist soil sample, try to make the soil into a ball. If it holds together even when dropped from waist high, you have a clay soil.
                                            iii.     Soak soil sample in water to remove the organic material that floats. Allow sample to settle in a clear container to observe the various layers of soil that develop. Make observations on the properties of the various layers to determin their compositon. Allow samples to dry and observe changes at various moisture levels.
1.     Color, smoothness, stickyness, grittyness, hardness, plasticity, size and shape of sample.
b.     Students do research on web, in textbooks, or other sources for information on clay and its properties and products.
3.     Setup and Tools:
a.     Canvas or work board for each student.
b.     Wash Station: Tubs of water and sponges for washing.
c.     8 oz. chunks of clay, 2 to 3 per student.
d.     Set up projector for VTS
e.     Samples for discussion.
f.      Tools ready to distribute.
g.     Pots of slip
h.     Brushes for slip
i.      Scorers (comb pieces)
j.      Wooden modeling tools
k.     Damp sponges for moistening clay
l.      Bucket for clay scraps
4.     Introduction of Artist in Residence
5.     Students share results of the investigations they have done.
6.     VTS: Visual Thinking Strategies – Classroom Teacher
a.     Various ceramic objects and photos of ceramics.
b.     Use open-ended questions. Accept all observations.
                                               i.     What’s going on?
                                             ii.     What do you see that makes you say that?
                                            iii.     What more can we find?
7.     What is Clay? – Artist Description
a.     An introduction to origin and properties of clay
Clay: From Wikipedia, the free encyclopedia
Clay is a fine-grained natural rock or soil material that combines one or more clay minerals with traces of metal oxides and organic matter. Clays are plastic due to their water content and become hard, brittle and non–plastic upon drying or firing.[1] Geologic clay deposits are mostly composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure.[2][3] Depending on the content of the soil, clay can appear in various colours, from white to dull gray or brown to a deep orange-red.

Gay Head cliffs in Martha's Vineyard consist almost entirely of clay.

a.     Formation
                                               i.     Clay minerals typically form over long periods of time from the gradual chemical weathering of rocks, usually silicate-bearing, by low concentrations of carbonic acid and other diluted solvents. 
8.     Stages of pottery making.
a.     Lump of clay
b.     Green ware
                                               i.     Green ware is water-soluble.
                                             ii.     Leather hard, firm and slightly flexible.
                                            iii.     Dry brittle and fragile.
c.     Bisque firing
                                               i.     Vitrifies clay, no longer soluble in water.
                                             ii.     Called bisque ware.
                                            iii.     Glazing is done at this stage.
d.     Glaze firing
                                               i.     Glaze ware is finished pottery or ceramics.
9.     Starting with pinch pot, we recapitulate the history of ceramics over the ages.
a.      Origin story of ceramics, optional.
10.  Make pinch pots. - Artist will demonstrate
a.     Demonstrate slip & score for attachments
b.     Hand Yoga- connecting hands to brain, dexterity and strength
c.     Distribute clay
d.     Artist and classroom teacher circulate, encourage, assist and suggest
11.  Start cleanup 10 mins. before end of period, give 5 min
a.     Students bring pieces to teacher when done
b.     Clay scraps in bucket
c.     Return all tools
d.     Wipe canvas with Damp sponge
e.     Roll up canvas
f.      Check room for neatness
12.  Summary/review/reflection/conclusion of lesson (consider reviewing the hook or text that you introduced at the beginning of the lesson)
13.  What would you do next time, what would you not do next time?
14.  Standard for Physical Sciences
                                               i.     In grade five, students learn that elements and their combinations account for all of the types of matter in the world and that living organisms and most materials are composed of just a few elements. They learn that all matter is composed of atoms that may combine to form molecules and that during chemical reactions the atoms in the reactants rearrange to form products with different properties. The introduction to chemical reactions and the concept that atoms combine to form molecules requires students to clearly distinguish between molecules and atoms and chemical compounds and mixtures.
                                             ii.     Students are introduced to the idea that the organization of atoms on the periodic table of the elements is related to similarities and trends in the chemical properties of the elements. They learn that scientists have developed instruments that create images of atoms and molecules revealing well-ordered arrays of atoms and molecules. They learn that metals have properties in common; some metals are pure elements, while others are composed of a combination of elemental metals. Students also learn the common properties of salts.
15.  Visual and Performing Arts Content Standards Grade Five:
Historical and Cultural Context 3.0 to 3.4
