Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.

Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.

Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.

Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs.

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.

Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
