Disassembling and Reassembling Objects with Small Pieces

2nd Grade

Objects that are made of small pieces can be taken apart and built into something new.

• Make observations (firsthand or from media) and/or measurements of a proposed object or tool or solution to determine if it solves a problem or meets a goal.

• Use quantitative data to compare two alternative solutions to a problem.

• Generate and/or compare multiple solutions to a problem.

• Describe how specific images (e.g., a diagram showing how a machine works) support a scientific or engineering idea.

• Communicate information or design ideas and/or solutions with others in oral and/or written forms using models, drawings, writing, or numbers that provide detail about scientific ideas, practices, and/or design ideas.

• Develop a simple model based on evidence to represent a proposed object or tool.

• Students observe objects may break into smaller pieces, be put together into larger pieces, or change shapes.

• Students observe the shape and stability of structures of natural and designed objects are related to their function(s).

• Matter exists as different substances that have observable different properties. Different properties are suited to different purposes. Objects can be built up from smaller parts.
