E1: Show that large things are made up of smaller pieces.

Curriculum Organizing Questions	What parts make up this object? What would happen to this object if we removed this part? What would happen to this object if we changed this part?
Elaboration	Students should practice identifying the parts of things and how one part connects to and affects another. Students should predict the effect of removing or changing parts. ESES p. 121
Specific Ideas	Objects can be described in terms of the materials they are made of (clay, cloth, paper, etc.) and their physical properties (color, size, shape, weight, texture, flexibility, etc.) Benchmarks 4D1 Most things are made of parts.Benchmarks 11A1 When parts are put together, they can do things that they couldn't do by themselves. Benchmarks 11A, essay p. 263 Something may not work if some of its parts are missing. Benchmarks 11A2
Developmental & Instructional Implications	Carefully designed instruction starting in the earliest grades can lead to better understanding of the particulate nature of matter when students reach middle school.
Examples	Classrooms can have available a variety of dissectable and rearrangeable objects, such as gear trains and toy behicles and animals, as well as conventional blocks, dolls, and doll houses.Driver p. 85
