Students will examine the physical properties of soil by studying works of art, testing local samples, and using soil to create their own works of art.Pre-Columbian Costa Rican and Nicaraguan ceramic artists excelled in combining 1. After students have determined the texture of each sample, label and group the local soil samples as clay, sand, and silt. The analysis of soil composition and manufactured clay may be used to assess whether students are able to apply knowledge of clay’s properties. The properties exhibited by structural clay products are determined by particle size, firing temperature, and ultimate microstructure. Ask students to use their comparisons of the sand, silt, and clay to evaluate each type of soil to be used for art making. It is fertile. Soil Texture. After students have a list of observable characteristics, ask the students to work as a group to write a paragraph or create a 3.

Learn vocabulary, terms, and more with flashcards, games, and other study tools. Lead a discussion about natural resources. Students will measure each layer of their “soil shake” and create a ratio of each layer of the soil’s texture compared to the entire sample. As a class, discuss the reasons the store-bought clay has been manufactured to accentuate particular physical properties.15. During the presentations, create a class chart that lists clay’s physical properties, noting areas of variability such as color and texture.5. Most clays contain several different types of clay minerals with different amounts of metal oxides and organic matter; this is what sets the different types of pottery clay apart. Have the groups present their analysis to the class.4. The size of its particles is small. Allow students to make observations of each group (sand, silt, clay) and compare and contrast the soil samples by using the 12. Use left and right arrows to navigate between tabs.

Using a large (11×14) piece of poster board, have students sketch a dramatic nature scene. Clay may also exhibit the property of plasticity where shear strength and compressibility are closely related to water content. Share the background information about each piece of ceramic art.
