Use suitable tools, techniques, and materials to make a drawing or build a model or prototype of the proposed design.
In earlier grades, students learned to design a solution to a simple problem, using an elementary version of the technological design process. In grades 4-5 students learn to distinguish between science and technology and to work individually and collaboratively to produce a product of their own design. They learn that people in different cultures use different materials and technologies to meet their same daily needs and increase their understanding of tools and materials. Students also develop their abilities to define problems that can be solved by modifying or inventing technologies, to create and test their designs, and to communicate what they learned. These capabilities help students understand the value of science and technology to meet human needs and provide them with valuable skills for everyday life.
Possible solutions should be tested to see if they solve the problem. Building a model or prototype is one way to test a possible solution.
