Different problems need different solutions, but engineers follow the same steps to solve them. Discover the path engineers take to find new solutions or improve old ones.
Engineers often look to nature to help them solve problems. Read about human technologies that have been inspired by animals and plants.
Engineers build models to help them test how well their solutions will work. Read about how testing small-sized models helps them spot mistakes, make improvements, and create the best solution possible!
Did you know that a problem can have many different solutions? Read about how an engineer finds the best solution to solve a problem or meet a need.
Read about the kinds of jobs that people do as engineers, and how they use math, science, and creative thinking to solve problems.
