Review the Science Concept: Physical vs.Examples: On a picnic and it begins to rain students are playing with a ball in the living room until someone hits a lamp and it breaks group of friends wait to yell “surprise” for a surprise birthday party.Groups will practice forming 2-part tableaux of a particular scenario. Dialogue will be added into the silent scenes through thought-tracking. Groups will then be asked to form various scenarios within their groups silently.Go over the Principles of Tableau (see Downloads: Anchor Charts-Chemical & Physical Changes).Groups will be asked to form various shapes within their groups silently. Introduce the art form of Tableau with a warm-up: Silent Tableau.Cotton fabric cut into squares for dyeing (a sheet works well).Suggested Prompts for Dramatization of Chemical & Physical Changes (see Downloads).Tableau Preparation Sheet (see Downloads).Anchor Charts: Chemical/Physical Changes (see Downloads).Shibori: A Japanese manual resist dyeing technique, which produces patterns on fabric.When the indoxyl compound is oxidised, it becomes blue: indigo blue. When the glycosidic bond is broken, the indoxyl is freed. Indican: The compound that yields indigo blue, is a glycoside: a sugar (in this case a form of glucose) bound to another molecule, indoxyl.It is the blue often associated with blue jeans. A large percentage of indigo dye produced today – several thousand tons each year – is synthetic. Historically, indigo was a natural dye extracted from plants, and this process was important economically because blue dyes were once rare. ![]()
