Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot. Examples of reversible changes could include materials such as water and butter at different temperatures. Examples of irreversible changes could include cooking an egg, freezing a plant leaf, and heating paper.

Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties. Observations could include color, texture, hardness, and flexibility. Patterns could include the similar properties that different materials share.

Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose. Examples of properties could include, strength, flexibility, hardness, texture, and absorbency. Assessment of quantitative measurements is limited to length.

Make observations to construct an evidence-based account of how an object made of a small set of pieces can be disassembled and made into a new object. Examples of pieces could include blocks, building bricks, or other assorted small objects.
