Dinosaur fossil tiles: early childhood.The Art Problem Create a simulated fossil using toy plastic dinosaurs and clay. Materials clay, cut into slabs about 4 x 5" (10 x 13 cm) and 1 " (2.5 cm) thick; small plastic dinosaurs, at least three per table; shells; water; wet paper towels for cleanup. Procedures Ask students: What are dinosaurs? What does it mean to say they are extinct? How do we know dinosaurs once existed? What are fossils? How were they made? Explain that our knowledge about dinosaurs comes from fossilized fos·sil·ize v. fos·sil·ized, fos·sil·iz·ing, fos·sil·iz·es v.tr. 1. To convert into a fossil. 2. To make outmoded or inflexible with time; antiquate. v.intr. dinosaur skeletons. Demonstrate how they will make fossil tiles from plastic toy dinosaurs (since no plastic dinosaur skeletons are available). Distribute clay and plastic dinosaurs. Tell students to let their dinosaurs "fall over" on their sides in the clay. Encourage them to push hard enough to make a good impression without flattening
The flattening, ellipticity, or oblateness of an oblate spheroid is the "squashing" of the spheroid's pole, down towards its equator. the clay too much. Suggest that they also use shells to make impressions. Students can rub a little water into their clay if it begins to crack. Let the fossil tiles dry, and then fire them if using real clay. They can be left unglazed and rough to look like real fossils or glazed glaze n. 1. A thin smooth shiny coating. 2. A thin glassy coating of ice. 3. a. A coating of colored, opaque, or transparent material applied to ceramics before firing. b. with a clear glaze glaze, in pottery glaze, translucent layer that coats pottery to give the surface a finish or afford a ground for decorative painting. Glazes—transparent, white, or colored—are fired on the clay. . Assessing Learning Can students correctly explain the meaning of the terms dinosaur, extinct, and fossil? Can they accurately explain how fossils were made? Nancy Walkup walk·up also walk-up n. 1. An apartment house or office building with no elevator. 2.
