Material Properties

Grades 1-2

Objects can be classified using observable properties.

• Plan and conduct an investigation collaboratively to produce data to serve as the basis for evidence to answer a question.

• Make observations (firsthand or from media) and/or measurements to collect data that can be used to make comparisons.

• 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.

• Make predictions based on prior experiences.

• Make observations (firsthand or from media) to construct an evidence-based account for natural phenomena.

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

• Children recognize that patterns in the natural and human designed world can be observed, used to describe phenomena, and used as evidence.

• 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.

• A situation that people want to change or create can be approached as a problem to be solved through engineering. Such problems may have many acceptable solutions. Asking questions, making observations, and gathering information are helpful in thinking about problems. Before beginning to design a solution, it is important to clearly understand the problem.
