While scientists study how nature works, engineers create new things, such as products, websites, environments, and experiences. Because engineers and scientists have different objectives, they follow different processes in their work. Scientists perform experiments using the scientific method<span>; whereas, engineers follow the creativity-based </span>engineering design process<span>.(I hope this helps)
