Key Idea.
Section 1
Engineers Study Nature's Designs
Animals have body parts with special shapes that help them do certain jobs. The shape of a part is its structure, and the job it does is its function. A bird's wing structure is perfect for flying, while a fish's fin structure is perfect for swimming.
Engineers study these amazing designs in nature. They learn how a structure creates a function. Then, they copy these natural ideas to build new things that can help people.
Section 2
Engineers Follow a Design Cycle
Engineers follow special steps to solve problems. First, they learn about the problem and get ideas, like studying how a cockroach moves. Then, they create a plan or a drawing for their design.
With a plan ready, they build a first model called a prototype. They test this prototype to see how well it works and what needs to be better.
Expand to review the lesson summary and core properties.
