PreK-2

C1: Demonstrate that living things are made up of parts.

Curriculum Organizing Questions	What are the parts of this item? What can this thing do that its parts alone can not? What does this part do? How is this part like this other part? What happens when a part is changed or removed? What are some of the parts to the human body? What do the parts of the human body do?
Elaboration	Students should practice identifying the parts of things and how one part connects to and affects another. Benchmarks p.264
Specific Ideas	Most things are made of parts. Benchmarks 11A1 Something may not work if some of its parts are missing. Benchmarks 11A2 When parts are put together, they can do things that they couldn't do by themselves. Benchmarks 11A3 Each plant or animal has different parts that serve different functions. NSES C1b Different kinds of living things sometimes have similar parts. Humans have distinct body structures for walking, holding, seeing, talking, hearing, etc. NSES C1b
Developmental & Instructional Implications	Classrooms can have available a variety of dissectable and rearrangeable objects, such as gear trains, toy vehicles, and animals, as well as, conventional blocks, dolls, and doll houses. Students should predict the effects of removing or changing parts. Frequent discussion of how one thing affects another lays the ground for recognizing interactions. Benchmarks p. 264
